Audition begins in the external ear, when collected sound waves strike the tympanic membrane. The resulting vibration of the tympanic membrane converts sound waves into mechanical energy, causing the middle ear bones to move back and forth. This mechanical energy is further transformed to a hydraulic form of energy in the cochlear fluid of the inner ear, which activates the sensory hair cells in the cochlea and transforms the hydraulic energy to electrical never impulses.
當收集的聲波撞擊鼓膜時，Audition begins in the external ear聽覺是從在外耳開始。The resulting vibration of the tympanic membrane鼓膜的振動結果把聲波轉換成機械能，造成中耳聽骨前後移動。這機械能在內耳的耳蝸液體中進一步被變換成一種hydraulic form of energy水壓能量的形式，在耳蝸中激活感覺毛細胞並且從水壓能量變換到electrical never impulses電神經衝動。
The nerve impulses are transmitted by vestibulocochlear nerve (CN VIII) fibers to the cochlear nuclei in the brainstem. The cochlear cells project these nerve impulses to multiple synaptic points in the brain stem and the thalamus before transmitting the impulses to the primary auditory cortex in the temporal lobe. The auditory impulses travel from the primary and secondary auditory cortex to the Wernicke (associational language) area, where the auditory signals are analyzed and interpreted into meaningful language-specific messages.
The nerve impulses神經衝動由前庭耳蝸神經(CN VIII)纖維傳達給在腦幹中的耳蝸核。before transmitting the impulses to the primary auditory cortex in the temporal lobe在顳葉傳送脈衝給主要聽覺皮層之前，耳蝸細胞投射出這些神經衝動給在腦幹和丘腦的多胞突接合點。聽覺衝動從主要和次要聽覺皮層移動到Wernicke (聯想語言)區Wernicke (associational language) area，在此處聽覺信號被分析並且interpreted into meaningful language-specific messages被譯成具有特定語言的訊息。
