通常总是以为空间感觉是由视觉获得的。眼睛的这一本领掩盖了耳在这方面的重要性,其实耳一直在监测着我们的周围环境。人们早已知道声音能引起人主观的音调和响度感觉,但直到不久以前才认识到耳还能利用两耳间物理条件的差异来作声音的定位。关于人耳声音定位的机制有很多学说,最主要的是强度、时间和位相学说。许多作者认为声音在两耳间产生的强度、时间和位相差是人耳具有定位功能的原因。还有一些作者认为耳郭的屏蔽、头部运动、视觉功能、肩部反射、触觉功能、半规管功能也是声音定位的因素。许多动物试验证明脑部上橄榄区对双耳间声 It is always the impression that space is visually perceived. This ability of the eye masks the importance of the ear in this respect, and in fact the ear has been monitoring our surroundings. It has been known for a long time that sound can cause subjective tones and loudness perceptions, but it was not until recently that the ear was able to make use of the differences in the physical conditions between the ears for sound localization. There are many theories about the mechanism of human ear sound localization. The most important ones are intensity, time and phase theory. Many authors believe that the intensity, timing, and phase difference that sound produces between ears are the cause of the positioning function of the human ear. Some authors also believe that the ear shield, head movement, visual function, shoulder reflex, tactile function, semicircular canal function is also the voice positioning factor. Many animal experiments prove that the olive area on the brain of the ears between the ears
