济南汽车音响改装http://www.sdcarmusic.com/介绍早在一百多年前，就有人发现单耳失聪者，仍有辨认声源方位的能力，并提出过耳壳效应的设想，但不为人们所重视。直到本世纪六十年代，当立体声技术得到长足发展之后，人们认识到双耳效应对某些声源方位感觉难以解释，于是耳壳效应才得以被人重新认识。
Jinan modified car stereo presentation than 100 years ago, it was found that one ear deaf, there is still the ability to recognize a sound source orientation, and raised the idea ears effect, but not for people to pay attention. Until this 1960s, when stereo technology has made rapid progress, it is recognized that binaural effect of certain sound source position is difficult to explain the feeling, so was able to effect ears being re-understanding.

济南汽车音响改装谈到我们都可能做过一些有趣的试验，比如把耳朵往外拉成兜风耳，这时我们感觉到外界的声音突然变大变清楚了；如果把耳朵向后按到贴住头骨，又会发现声音减弱了。如前所述，耳壳有反射并聚集声音的功能。同时由于耳壳凹凸不平，因此，耳壳不同的部位所产生的反射声，比直达声稍迟进入耳鼓，形成比直达声极短延时量的重复声，重复声比直达声的延时量因入射角不同而异。
Jinan car audio conversion comes to us could have done some interesting experiments, such as the ears, ear pull it into a ride, then we feel that outside voice suddenly change into clear; if the ear back to stick to the skull by , will find that the sound diminished. As mentioned earlier, there are ears and reflected sounds aggregation function. Same time as the ears uneven, therefore, reflected sounds different parts of the ear shell produced, slightly later than the direct sound into the ear drum, form a repeating sound than the direct sound very short amount of time delay, repeating the direct sound than the sound delay amount because of the angle of incidence varies.
   
济南汽车音响改装http://www.sdcarmusic.com/提醒大家耳壳效应对判断来自听音人背后的声音也有效，当一个声音来自背后时，耳壳将阻挡了这个声音的高频泛音，这样，同前方的声源相比，出现了明显的音色差；同时，由于耳壳的遮蔽作用，来自背后的声音将不产生重装音。大脑听觉区将这些信息同以往掌握的信号相比较，从而得出声源出自背后定。
Jinan car audio conversion ears remind you judge the sound effects on listeners from behind is also effective when a voice from behind the ears to block the sound of high-frequency harmonics, so that compared with the sound source in

front, there is a clear difference in tone; at the same time, due to the masking effect of ears, the sound from the back will not produce sound reloading. Auditory area of the brain that information with the previous master signal compared to arrive at a sound source from behind the set.
