How To Evaluate The Listening Ability Of The Human Ear To HiFi Equipment?

Auditory adaptation

Humans can adapt to the links around us in many ways, such as temperature, brightness, smell, color, sound, etc. For example, our vision system can adapt to color temperature, white balance, and brightness, etc. This adaptation is not achieved by the P file of many high-end cameras.

We can accept serious loss of sound quality, such as a large amount of linear and nonlinear distortion in mobile phone communication. Even discerning audiophiles will not reach the point where they can't stand the call quality without using a mobile phone.

Our auditory system can also "spectrum compensation" for not so good sounds. Watkins' research has proved that this type of spectrum compensation works within a certain range, but it will fail if it exceeds a certain range.

Auditory adaptation will further weaken the position of hearing in our daily evaluation of HiFi equipment. Because on the one hand, we can accept and compensate for not-so-good sounds through auditory adaptation, on the other hand, we will be affected by the prejudice of non-auditory factors that cannot be ignored, and the results can be imagined. Based on my personal work experience, professional training and experience can help people overcome auditory adaptation to a certain extent, so that they can accurately grasp the current sound in real time without comparison during the tuning process. This is my personal experience. I practiced tuning when I was just working and felt that I had already tuned it, but it took half an hour to listen to it and I found the problem. This overcoming of auditory adaptation can improve the ability to accurately evaluate the sound, but it can also lead to the inability to adapt to the sound in most situations, and thus make oneself more demanding when listening seriously.
