我们平时听录音和欣赏音乐会,美妙音乐都是通过空气的传导为我们所感知。而生活当中我们的听觉不仅仅是依靠空气传导,有些情况下骨传导发挥重要作用。让我们先看一下耳的生理结构: 耳在结构上分为外耳、中耳、内耳三个部分。外耳又包括耳廓和外耳道。中耳由鼓膜、听小骨及与之连接的鼓膜张肌等若干部分组成。在内耳中耳蜗的螺旋器(即柯蒂氏器)上有听觉感受器,由听觉神经与大脑的 We usually listen to the recording and enjoy the concert, wonderful music is through the air conduction for us to perceive. In our lives, our hearing depends not only on air conduction but in some cases bone conduction plays an important role. Let us first look at the physical structure of the ear: the structure of the ear is divided into the outer ear, middle ear, inner ear, three parts. The outer ear includes the pinna and external auditory meatus. Middle ear by the tympanic membrane, ossicles and connected with the tympanic membrane tensor and other components. In the inner ear cochlea spiral (ie, Corti) on the auditory receptors, the auditory nerve and the brain
