道格拉斯 L. 奧利佛: 聽覺的科學

聽覺的科學

你能辨識出聲音並找出它們的位置，可能要感謝聽覺系統。這個系統主要由兩部分構成：耳朵和大腦。耳朵把聲能轉變成神經訊號，大腦則接收和處理那些訊號所含的資訊。道格拉斯 L. 奧利佛帶我們走一趟聲音進入耳朵之旅，了解聽覺如何運作。

Hearing relies on a remarkable collaboration between the ear and the brain, converting waves of air pressure into distinct thoughts and actions. A mosquito's whine, for example, is detected as specific vibrations that travel through ear structures before the brain pinpoints their source. This process depends on specialized hair cells and the unique properties of the basilar membrane, which can distinguish everything from a whisper to a symphony. Yet, hearing loss remains highly common, often caused by damage to these delicate biological components.
