[Home Theater Network HDAV.com.cn] Many times we have this kind of question, why is the same set of sound, each person's sense of hearing and evaluation are different?
Human hearing does not exist independently. It has a great relationship with the external factors of the person and the surrounding, and has a great influence on the evaluation of the sound reproduction of the audio equipment. Generally, there are mainly the following factors.
1. Physiological factors: Because of the environment and age, people's auditory system is constantly changing. Young people are more sensitive to subtle sounds, while older people may be slower. Some people are more sensitive to high frequency sounds, while others are more sensitive to low frequency sounds.
2, regional and cultural factors: because people are in different regions, or cultural levels are different, the preferences for music are also different. Africans love music that is more rugged and percussive, while the British love symphony, light and light music. In southern China, people love Yue opera and Shanghai opera, while northerners love Beijing opera, Beijing opera and so on. People with higher education tend to prefer Western music, while the average person likes national music.
3. Psychological and emotional factors: In today's society, competition in all walks of life is fierce, various kinds of affairs are complicated, and people's psychology and mood change greatly. If people are unhappy, give them a cheerful music. Conversely, when people are in a good mood, they will appreciate the low and serious music, and people will be disgusted with this music.
In addition to the above main reasons, there are social, ideological, economic, climatic, and different degrees of familiarity with a certain audition track, etc., which enable people to form a personalized auditory system. Therefore, although some of the audio equipment has good technical indicators, some people feel that the replay sound is still unsatisfactory. Therefore, a set of high-quality audio equipment, if you let a lot of people to evaluate, it may be difficult to get a consistent view, which also puts a layer of mysterious color on the evaluation of the audio equipment replay sound, with the "difficult to adjust" Words to express the evaluation and purchase of audio equipment is more appropriate.
