Historical analysis of audio culture The author of this article is a member of the professional audio enthusiasts team and a member of the audio enthusiasts. He has participated in the formulation of national audio standards, and has many practical activities such as product evaluation, appraisal and the training of audio professional teams. Encouraged by the sound industry and the expansion of the team, I also feel the need to popularize the education of sound technology and sound culture. This is to improve with the majority of audio enthusiasts. Audio products are more "into the room" people's home and play a good physical and psychological , Art, and cultural effects are directly related. Here, I will only briefly mention some questions and suggestions, and ask the readers and friends of "Sound World". The audio world is rich and varied and endless. Before the advent of the modern audio system, it was composed of four parts: natural sound, social practice sound, art performance sound and language sound. Modern sound records, transfers, appreciates and recreates them. The precious sound art and the appearance of the sound world reproduced in different places have become very important and irreplaceable communication tools. Moreover, the rapid development of recording technology and the rapid improvement of the level of recording creation have created many new art varieties, that is, traditional art has also been enriched and expanded. At present, the majority of urban and rural people have generally become or are becoming appreciators and beneficiaries of the audio art culture, and some have reached the "fever level", or have started recording-production-appreciation creative activities in the field. I think that in the 21st century, the rapid development of audio culture and the wider popularization and improvement will make us wonder and feel extremely relieved.

1. It is very necessary to pay attention to the scientific requirements of audio production and consumption, creation and appreciation.
Let's start with a few points of view by linking production, consumption and appreciation.
First of all, it is necessary to learn and understand before buying audio products. It is indispensable to consult books, experts and enthusiasts with application experience. No matter how simple the audio product is, it is a system, or there are several links connected into an organic whole. It should not only understand the relationship between these links, but also accurately operate the switches, buttons, knobs, faders, etc. Unlike food and clothes, you can eat and wear them when you buy them. For example, the burned-out speakers that often occur are mostly related to not understanding the operating procedures. Use a sound system consisting of a CD player (or DVD player), a power amplifier, and dual speakers. After plugging in the power supply, turn on the CD player first, then turn on the power amplifier, and finally turn on the speakers (if it is an active speaker) Words), and the knobs responsible for the output should be turned off first. After the above operation is completed, turn on the knob (place it in a suitable position). I don't listen anymore. If you want to shut down, the operation procedure is just the opposite. Turn off the output knob first, then turn off the speaker, power amplifier, and CD in turn, and finally pull out the power plug. If the plan is to save trouble, all links are open, but the two actions of plugging in and unplugging are extremely harmful. Because this will cause a relatively high pulse signal to come and go from the voltage, it is very fierce to impact the power amplifier, the speaker, you have listened to dozens or hundreds of programs, and there is no such fierce high pulse signal damage system Even if the speakers are not burned out at once, the speed of sound quality will be greatly accelerated. In other words, the service life is shortened and the sound quality is deteriorated. Yes, the system can be used for ten or twenty years without burning out and sound quality deterioration.
We only mentioned the concise operating procedures of the applied sound system. Other adjustments involving volume, timbre, left and right channel balance, sound field mode, etc., should be understood in order to be properly applied and achieve the artistic effect you want, otherwise, put The creations of artists and professional audio workers are distorted. I do n’t understand. What a pity!
"It's a pity" that things often happen in the relationship between the sound system and the appreciation environment. Many customers have no understanding of the acoustic relationship between the appreciation effect of the sound system and the appreciation environment before entering the audio store. It's natural to take the audio products home, which is actually only half right. The sound system is good, and it is completely necessary to ensure the technical quality, sound quality, art quality, and content quality of the program source (CD, LD, VCD, DVD, etc.)-appreciation is completely necessary. Therefore, I do n’t approve of selling low-quality, low-quality products to customers, and I also suggest that users should not put the price low on the top of the purchase of audio. The sales language of "low price, good quality" is not to be trusted. Our country The development status of audio technology in the world and even in the world determines that it is difficult for manufacturers to fulfill those fantastic promises. If we divide our national audio system into three major quality grades (especially speakers), it is very prudent to purchase low-grade products among them (the reason will be discussed later), and still choose high-end and mid-grade products as the object of purchase Just fine. I would like to remind friends with financial strength that they must look at high-end high-quality audio. The technical content, artistic texture and cultural character inside can not be measured by price, nor can most appreciators estimate; such brands are multi-faceted The quality products that the experts are striving for are full of their pursuit and love, and they are not understandable by national technical standards and corresponding electroacoustic measurement. This requires the method of subjective evaluation and art evaluation of sound quality to listen, judge and interpret. If users do not have this evaluation ability when purchasing products, it is recommended to seize three items: first, ask some audio enthusiasts to learn about the credibility and popular personality characteristics of some domestic and foreign famous brand audio; second, go to large Audio shops, especially those with better listening rooms, bring software suitable for listening to audio technology quality, sound quality, and art quality (like the 1989 national CD-like listed CD, some recordings and performances are of very good quality Symphony, folk orchestra, opera, dance, etc. CD, etc.), listening on the spot, comparing different brands, choosing the best from them; third, consulting with audio experts, asking them to help recommend and listen, is to pay a certain fee, It's worth it. The above-mentioned three items have scientific value, art evaluation and cultural positioning functions, which are more practical than the product test manuals and national test standards for speakers and power amplifiers. It can also be said that users carry out technical quality, sound quality and art for listed audio products The main basis for quality classification identification. It is better if you have the conditions to listen to them in the professional listening room of the broadcast, which is helpful to meticulously discover the various states and textures of the sound.
Carrying out technical measurements on the sound system, giving verification of the basic technical quality of the product and making concise signs and explanations to the user, this is a "thing-thing" scientific and technical investigation. The sound system is just different from many technical products. It serves people's physical hearing, psychological hearing, art appreciation, and auditory culture learning. It must integrate the overall system of physical, acoustic, physiological, and artistic culture. And ultimately it comes down to listening, appreciation, evaluation, interpretation.
Isn't it an exaggeration to say that the technique of "thing-thing" is simply bragging about being boastful, saying that it is "hot"? If manufacturers, merchants and consumers all pay attention to the subjective evaluation of sound quality, carefully evaluate the technical quality, sound quality, art quality and content quality of the product through hearing and related sound environment and evaluation format, this is really Reflects the cultural system attributes and artwork characteristics of the sound system. It should be said that this kind of human-centered service for hearing appreciation is a more comprehensive and essential scientific experiment, and is the most practical test of the overall effect of the system. We are happy to see that some manufacturers and professional audio workers and enthusiasts (including customers with high artistic requirements and high cultural expectations) have begun to value and participate in the subjective evaluation of sound quality. We also regret to point out that most of them still do not pay attention and do not understand , Does not have the actual wisdom ability of subjective evaluation of sound quality and artistic evaluation. The final quality of the audio system should be based on this actual evaluation. For users, this is the first quality requirement, which can be called the terminal texture. At least, it should be related to production costs, technical investment, and marketing circulation. Wait for the calculation to determine the price. My impressions of contact with many audio systems are not all good. Ignore the overall quality of the subjective evaluation, but the price is chaotic, not individual. Many similar audio systems of the same grade (terminal texture) can be poor. Two or three times, even more surprising is that the sound quality and artistic quality of 3,000 yuan can be better than 8,000 yuan, and those with more than 10,000 yuan are less than 4,000 or 5,000 yuan, or they are of similar texture.
This means that for manufacturers, the product price must have sufficient conditions to restrict, and it must be systematically and practically grasped. It must have instructions and restrictions on its direct sales, wholesale, and consignment. The price and value of certain brands The difference is related to the huge profits of the sales and the arbitrary price increase. The sales profit of a set of audio is more than one thousand yuan, or even two or three times the wholesale price. It is not appalling! This poses a sharp question to the user. Do n’t simply think that the high price is good. The best way to prevent cheating is already mentioned. Please ask the expert to help evaluate it.
We emphasize the combination of objective measurement and subjective evaluation. As a user, we must pay particular attention to the latter. As a manufacturer, if we want to improve product quality, in the fierce competition of this special cultural commodity, occupy a position, improve credibility, expand the results, pay attention and grasp Good subjective evaluation is a must. Objective measurement and product design and production are subject to subjective evaluation. The formulation of the "last hurdle" is only for ex-factory products. For the entire production-design-measurement system, subjective evaluation should serve as a reminder and promotion. Although it is difficult to use straightforward technical parameters to modify production, design, Measurement, but you can find the difference in hearing effect of different design structures in comparison and identification. The production of a brand prototype should integrate design, production (including material and component selection), inspection, and subjective evaluation into an overall operations system. Infiltrate the actual technical research work, so that it is more targeted and takes effect quickly. Some decision makers attach great importance to the process design and aesthetic design of product appearance. This is good. Ignoring the subjective evaluation and the terminal texture of the overall system should not be. In the test of market competition and subsequent purchasing power, I am afraid that I will have to suffer In the face of the reality of "supply exceeds demand", we should pay more attention to the technical quality, sound quality and art quality, and upgrade the grade to produce a product culture style that makes more and more people feel it Okay, love is born. This is the hope that others can't take away, and even slogans such as "good quality is the price is expensive!" Will be laughed at by enthusiasts and enthusiasts!
The audio that users usually say refers to the recording-playback system. As a civilian product, it is mainly to improve the playback and enjoyment effect. The large audio system we are talking about should also include a playback (or appreciation) environment, listening format and program software. The four parts are combined into a large system to ensure the scientific mechanism and artistic effect of auditory appreciation; many people ignore the truths, conditions, and mechanisms in this, regardless of the appreciation environment, which is common. Their desire to obtain good artistic effects is very strong, but it is often difficult to achieve their goals. In the end, they complain of 20,000 or 30,000 yuan spent in vain. In fact, money is not spent, if you listen to it with good headphones, it will be much better than the sound from the speakers. This is because the sound emitted by the speaker should be in your room, which is not too big, and is full of hard lime walls and glass windows, causing a lot of reflections and reverberations. These and the sound emitted by the speaker will mix together and "change the taste" , Or called "acoustic dyeing" and "acoustic interference" of the environment. In order to make the sound system replay the artistic effect of the program software, the corresponding environmental cooperation is necessary to ensure that it is not "seriously polluted". However, the room volume of most people is small (mostly between 10-20m2), and the ceiling is short (more than 2.4-3.0m), if the decoration needs to consider the acoustic needs of sound playback, it costs money More often than not, it will occupy a considerable amount of space in order to suppress the reflection intensity of the middle and low bass, and the sound reflection treatment of the treble also needs to be done at the same time. Of course, conditions and economic strength allow for reliable design-decoration is a matter of course. In relatively simple room conditions, there are still some ways and methods to help the artistic effects of relatively well-resourced program sources. Many newspapers and books have been introduced. I will briefly talk about a few important measures:
First set up the sound system and confirm the best appreciation area. In our country, most of the speakers are separated by left and right, and the radial axis intersects in the format of the best appreciation area. The distance between the two speakers is selected between 2 and 3m, especially the speakers should not be placed in the corner. The reflection will increase a lot; at the same time, it is better to listen to the music and try to find how far the speaker is from the back wall. It should be about 70cm, and you ca n’t hear the bass being exaggerated; in order to avoid high-pitched sound, the speaker should leave the glass window Far away, hanging a thick velvet curtain to it can better suppress the staining effect of the reflected sound of the glass; the reflected sound of the hard lime wall and roof also accentuates the sharp, hard and rough sound quality, and hang more texture around the room The fluffy thick fleece cloth, and then the dense wrinkles, which can obviously reduce the treble staining, make the playback sound softer and more natural, especially the left and right walls form a symmetrical reflection of the best appreciation area, especially hang it Wrinkled thick velvet cloth, because when people sit in the best appreciation area, both ears are very sensitive to this symmetrical reflected sound, they are almost the same as the radiated sound of the speaker, and they are received "Preferential treatment" has become the "first mover" and "heaviest one" in the treble dyeing, so it is more important for the velvet cloth to absorb these reflected sounds than the long-distance hard walls.
There are a few points about the best appreciation area: when professional workers record music, they are monitoring in this area, referring to the artistic effects of listening to require conductors, bands, and recording processing, polishing, and users follow the example in the most Listening in the Best Appreciation Area, which is the most critical measure for reflecting the overall artistic quality of the program source. It is inappropriate to think that "sit anywhere, you can hear the sound"; this best appreciation area is in dual speakers On the intersection point of the radial axis and within a small range before and after it, the positions of the left and right speakers must be symmetrical to ensure that the intersection point is equidistant from the midpoint (or outer midpoint) of the left and right speakers; the so-called "most "Best Appreciation Area" is a very narrow range. In the home appreciation environment, it is a narrow area of ​​more than 1m long and about 20cm wide. The front end is about 1.5m from the midpoint of the dual speaker connection (called the baseline), and the rear end is 2.5m. Left and right, the narrower the baseline, the more the best appreciation area moves forward, usually the front end is at least 1m away from the midpoint of the baseline (approximately the corresponding baseline is between 1.8 and 2.2m), in order to weaken the staining effect of the room You can sit in the front end area. If two or three people study the same program and want to find a consistent feeling, they should sit tightly in the best appreciation area. In fact, they sit on the vertical line at the midpoint of the baseline. Here If you tilt your head more than 30cm to the left and right, you will find that the sound image of the instrument has shifted. This is the first reason why you are strictly required to listen in the best appreciation area, and the second is to lead to changes in the balance and tone of the voice.
The bass radiated by the speaker is most likely to be affected by the room. In the case of limited volume, improper ratio of length, width and height, and difficulty in decorating the bass sound absorption structure, the hope for improvement is small. The speaker placement and The relationship between the corner and the back wall, please pay attention to this point. Friends who like to listen to symphony, orchestral music, opera, dance drama and other programs, it is best to practice headphones to appreciate, which can shield the room from the various adverse effects and make the program play, Singing and recording are more faithful. Of course, listening to headphones should not be too long, and the volume should not be too loud, which will cause hearing fatigue and can cause ear problems in severe cases. We should also be aware that at the same price, the quality of headphones is generally better than that of speakers, and even good headphones of 3,000 yuan are better than the sound quality of speakers of 10,000 or 20,000 yuan. Furthermore, the external sound interference of headphones is minimal and the original program source is maintained. The ability to structure information is the strongest. Therefore, it is very good in the sense of space, sound quality, real and vivid performance of singing skills, etc. Even the interference of distinguishing noise is effective, not to mention the use of AAD, ADD, DDD recorded CD Hear the difference in noise, that is, the CD discs that are also recorded in DDD are often compared, and the subtle difference in noise can often be detected. When we are engaged in recording and production, when we are worried that the speaker is not sure, we also use headphones to check. In addition to the superiority of headphones, this can also eliminate noise interference in the listening environment to a considerable extent, allowing you to concentrate and enhance the internal hearing ability, thereby improving the resolution accuracy. Maybe you use good headphones to listen to, even the editing of professional recordings, editing traces, and the shortcomings of the players' skills can be found. In the careful listening comparison between the speaker playback and the headphone playback of the same program source, it is likely that your hearing discrimination ability will be significantly improved. This is also the experience of some "audiophiles". As for using headphones, it does not disturb family members or affect neighbors.
The relationship between appreciating the environment and appreciating artistic effects is complex and dynamically changing. Different program sources are also different under the same environment and playback system. Families appreciate the diversity of the environment, which makes the solution to this problem face an embarrassing situation. If the room volume is larger, up to 30-40m2, I still recommend some acoustic decoration. For audio system users with small rooms, under the condition of the same speaker sound quality, do not pursue large size, but choose the smaller one (bass is also better), which is convenient for arrangement in the living room. Of course, comparing loudspeaker systems of different sizes requires that they respond well to the sounds of high, medium, and low instruments. It is recommended to use the excellent recording quality of "Maeller Ninth Symphony", "1812 Overture", " From the New World, etc. to listen to and say goodbye, and compare melodies and harmony to piano in the second group of piano music, you can also perceive how well the equipment reacts to the sound of bass instruments.
It can be seen from the above descriptions and suggestions that there are indeed complex relationships between many disciplines and large audio systems. From the practical point of view, we emphasize their operability and indicate the feasibility of some scientific experiments. For the majority of audio users, is this more practical and easier to grasp? !
2. What kind of audio culture concept should be established?
The concept of audio culture is related to the discussion in the previous section and is a broader category. I don't want to discuss the theoretical ideas on the concepts, but to give some real ideas for the actual production and consumption of audio culture, and come up with some ideas, mainly related to the issues of physiological hearing and basic effects of psychological hearing of audio culture consumption.
Audio culture consumption not only refers to purchasing an audio system, but also emphasizes how to use it, how to listen, what to listen to, what to learn, and how it is affected. The "physical hearing and psychological hearing problems" refers to the basic effects produced by the sound phenomenon's long-term effect on people's listening. Art experience, cultural experience, etc. are based on this basic effect and delayed. If the basic effect (or It is said that the basic reaction ability is not good, and the "growth" and "delay" will produce invisible hearing impairments.
I think that the understanding and attention paid by manufacturers and consumers to the basic effects of physiology and psychology is not enough, and they are not even in the sense. They are thinking, which is very detrimental to the cultivation and improvement of the overall national physiological and psychological quality. of. For many people in reality, it is still quite common to suffer from adverse effects and still consume blindly. With the rapid improvement of economic living standards, the sound system has been popularized in various life, production, culture, and social activities. It is particularly worthy of our reflection.
Listening to headphones and loudspeaker sound reinforcement at high sound pressure levels is harmful. Professional work and hearing tests have proved that between 80 and 90 decibels, continuous listening will cause fatigue in 15 to 20 minutes, reducing the ability to distinguish and grasp sound information. Heavier fatigue (not only auditory), even earache, nausea, and upset mood. The reason why traditional music works and singing use "fff" and "ffff" less, and not to continue with such intensity, is to empirically solve the reasonable need to adapt to auditory listening. Most of the music dynamics move between more than 30 decibels and more than 70 decibels. It is because the hearing burden is not heavy, but it can be adjusted and feel more comfortable. But popular music performances and business hall sound reinforcements are often much higher than 90 decibels, and even more than 100 decibels. They are called "deafening" by many people, but many young people think "The most enjoyable, such an exciting opportunity at home and at school." It's so much more enjoyable, and the hearing begins to be pure. They don't understand, or even understand, the reason why they must wear anti-noise earplugs or earmuffs when working in a noisy workshop. In foreign countries, the problems of ear diseases, neurological diseases, and accelerated aging of physiological and auditory systems due to uncontrolled audio consumption are not unique. China has also suffered injuries in this area. Especially for infants and students before junior high school, the hearing is in a particularly sensitive period. Parents and teachers should not pull them into the dance hall all the time, follow the trend to listen to popular music reinforcement performances, and even listen to headphones at home. Control the length of the listening time. If you ca n’t listen for half a day, do n’t even do your homework without leaving the headphones.
I also want to emphasize that hearing senescence comes much earlier and faster than other physiological functions. Moreover, people have no or indifferent awareness of its protection. For teenagers, poor physiological hearing protection will be a lifetime regret. Many people have been injured and are not self-explanatory. There are also a lot of people who think they can understand what is normal. We have conducted "listener training courses" for audio production enterprises. In addition to introducing the theory, experience and foreign norms of subjective evaluation of sound quality, we have conducted on-site listening training. There are dozens of participants, aged two Between fifteen and forty-eight years old. I am the main instructor of the field training. When I conducted the pilot survey, I found a huge difference in their hearing ability. The so-called "leading the bottom" means that at the beginning of the training, some music clips (for the purpose of subjective evaluation of sound quality, rich and vivid, and clear) are invited for everyone to listen to, and then each said what they heard, and found three major aspects. Differences: First, a few people are very sensitive and have a three-dimensional auditory response. Once they have heard it, they can hear many changes in the music signal, while some people are very slow, they can hear the rhythm, melody, etc. There is no change in performance information, sound and video movement status, hall reflection effect, etc. Even after the training class is over, these people have basically not improved significantly, and they wo n’t get the graduation certificate;
The second is to simplify the content of the investigation and test from the perspective of usual habits. Let everyone listen to a piece of music, point out what instruments are in it, where they are, and what the depth of field is. As a result, the students ’listening ability is still more obvious. , Can be divided into three or four grades;
The third is listening to language and singing. Please say the changes in the use of gas, breathing, length and sound quality of the prefix. Everyone still understands the semantics. However, it is not the individual who feels difficult to say the changes in the prefix sound induced by the state of language action; Let everyone ignore the semantics and only listen to the sound movement state of the preface. It is still more sensitive for the hearing-sensitive people, and the improvement for the dull people is less.
In this article, we introduce the differences in the auditory abilities of the trained people in order to arouse the thinking of the majority of audio consumers and more friends: First, the differences in hearing abilities have innate reasons, but more are acquired protection and consciousness or not Conscious listening training will directly affect the hearing ability, don't be indifferent to this; Second, those with sensitive hearing, mostly those who love music from an early age, hearing to 47-80 years old (early age) Well, this is the physiological and psychological auditory reaction ability accumulated by auditory training, which is the wisdom ability to keep his hearing young; third, hearing is not just listening to semantics, learning book knowledge, it can not only be found in music appreciation A world of sound with a lot of movement changes, and in addition to the meaning of language sound, it can also see the rhythm of sound movement. That is, many natural and social sound phenomena without clear semantic labels are also meteorological. If you can Listening much more than others, that is, the ability to feel and grasp the world is much stronger, and can be regarded as "the person who hears aura" Engaged in artistic creation, appreciation, and many cultural activities that use sound as a medium, "Aura" will show a strong ability. This is the basic ability to interpret sound phenomena, and is an indispensable tool performance ability to use sound to create sound art. , It is very beneficial to enrich the psychological performance of individuals, expand the psychological space, enhance the multi-level grasping ability of art and culture; Fourth, this important basic ability of physical hearing, psychological hearing and the basic effects of inducement and extension can be Regarded as the precious quality of natural persons, it is the basic condition of cultural construction that has not been fully valued by society and is generally understood by people. In the development of audio culture and the contact and use of various sound movement phenomena, if blindness is serious, especially in babies It is hard to make up for the consequences of hearing damage caused by youth.
Speaking of which, I want to reiterate why I advocate buying a good audio system instead of being able to use it at all levels like general commodity consumption.
Various sound arts for thousands of years are recognized as an infinitely changing, beautiful and touching culture, and an excellent crystallization of human wisdom. The recordings record, process, and create them, keeping the original flavor and enhancing the sublimation. If the quality of the sound system is not good, the actual value of the program source will be compromised. Originally, the civilian audio system was a bit worse than the professional recording system. If you did not choose from the best and still glide in the lower grades, the loss would be too great. "Too much loss" can not only see that the artistic effect is poor, but also realize that the rough sound itself is "deterioration training without paying tuition fees" for a long time. The habits, sensibility and psychological hearing of physiological hearing are reflected Ability and sensitivity will be adversely affected. Just as the bad results discussed in the previous example, there is a culture and a listening position, but because of the unprotected physiological training and psychological hearing, and good training, it is difficult to obtain a certificate of completion The result (this is an important employment certificate in the audio enterprise, which is collectively signed by experts and confirmed by the competent authority's seal). Of course, there are only a few people who have this kind of listener work, but one cannot think about it. If a person mainly obtains semantically clear knowledge from the many program sources replayed by the sound system, he is rich in sound changes. Sex and art movements are colorful and lack of sensitivity. Isn't that "wooden, dull"? One can imagine the lack of auditory experience. Even if this pitiful degree is not reached, there will still be "invisible regrets".
The following introduction may support this statement.
For decades, people used small radios to listen to AM broadcasts. When they went to the concert hall to listen to music, some people felt that they were not as natural and comfortable as the same music programs in the radio. Why is that? One of the reasons is that the bandwidth of AM broadcasting (the transmission frequency is limited to only 8,000 to 10,000 Hz) is much narrower than the overtone range of music (up to 15,000 to 20,000 Hz), so music programs The broadcast sound of the TV has a lot of high-frequency loss; there are many distortions added to the broadcast transmission and radio reception (or, to put it more generally, a lot of messy information that is not in the original sound information), which makes the program sound quality and so on. The deterioration is significant. Many broadcast professionals understand the "distortion and deterioration" in the media, but the general audience often regards the sound of the broadcast as real and natural. After listening for a long time, a physiological hearing habit is formed, "listening psychology setting", or , I thought it was good, and I love it. I have met such a person and asked him to listen to the newly recorded violin music under professional conditions and the folk music played by the Banhu collar. He said, "Why is it not like I have heard it on the radio?" Then ask him which one he likes ? He said: "I am still used to listening to the radio!"
If you use inferior sound systems to appreciate high-quality digital recordings from China and abroad, will it happen for a long time? Even if it is not sharp enough, it will also affect the ability to evaluate high-quality artistic effects and the ability to judge trials. This is worth serious consideration for teenagers who want to engage in art or like art and want to live a happy life. Some knowledgeable parents and teachers help and guide young people, and they deserve special praise and admiration.
I personally do not hate pop music, nor do I object to young people listening to it. However, I suggest that parents, teachers and teenagers diversify the selection of music programs. In this comparative appreciation, you will consciously and unconsciously discover that traditional music and professionally created serious music are more informative and change more Diverse, sound quality is more natural and harmonious, and as the accumulation of culture and the experience of life approaching, it will realize more aesthetic interest and cultural connotation, even the differences in psychological characteristics of different times and different regions, nations, and countries Being able to perceive it is closely related to listening to more kinds of music, improving the ability of mental representation, the ability to delay mental space, and the ability to train mental auditory thinking. Because of this, I advise young people not to be obsessed with popular music. In terms of writing, performance, and recording of popular music, most of them are shallower in consciousness, and the nature and comfort of information changes are lacking. Many programs especially emphasize direct emotional indoctrination and mobilize various aspects of the human body ’s emotional input , And the stimulation of hearing is mostly over-emphasized, and it is not suitable for physiological hearing and psychological hearing to quietly enter the quiet without interference. In this state, it is easier to travel to the sound world and reach the state of "opening up". , Let the mysterious sound be presented in the psychological space, and realize the so-called "whole-hearted devotion". I think that if this kind of experience summary, theoretical discussion and systematic research are connected with the enrichment and development of art, physiological psychology, anthropology, sociology, etc., it will broaden the understanding of audio culture. Audio consumption will provide effective guidance and promotion, saying that it is an important basic project for the quality education of social members and the construction of national culture, right? !
If manufacturers of special cultural commodities such as audio systems and numerous audio culture consumers can "understand, understand, and understand" these basic topics, they will bring many new Changes, product selection and listening to consumption, production design, inspection and marketing promotion will be enriched with many new concepts and new measures. Even social management will look at the audio culture and clean up audio pollution. !
