自从近年来有了立体声广播以后,就引起青少年强烈的兴趣。喜爱音乐的物理教师当然更想知道一些关于立体声方面的知识。下面介绍一点和双声道立体声有关的常识,供物理教师参考。一、声音和听觉通常,人们听到的声音是物体的机械振动,借助媒质传播,经人的外耳传入,作用于鼓膜,使其振动,进而通过中耳听小骨的振动,引起耳蜗内感觉细胞的兴奋,再经脑皮层听区,产生了听觉。听觉是整个听分析器活
Ever since Stereo Broadcasting was launched in recent years, there has been a strong interest among young people. Of course, physics teachers who love music often want to know something about stereo. Here are some common sense and two-channel stereo for physical teachers reference. First, the sound and hearing Usually, people hear the sound is the mechanical vibration of objects, with the media, the introduction of the human ear, the role of the tympanic membrane, so that vibration, and then through the middle ear to listen to the vibration of the small bones, causing cochlear sensation The excitement of cells, and then through the auditory cortex, resulting in hearing. Hearing is the whole listening analyzer live
