| 摘 要： | 认为听觉是人脑对作用于听觉器官的客观事物属性的反映,是听觉器官、脑和神经统一活动的结果.同时,介绍了听觉器官———耳的基本组成结构及其主要作用,将声学系统和电学系统进行类比,建立耳蜗对声音信号频率滤波、毛细胞的换能以及侧抑制神经网络对声信号缩减的数学模型,用模型分析听觉系统对不同频率的声音信号的处理方式.最后,运用上述理论,解释蝙蝠能感应超声波的原因.

| Abstract: | Hearing is the activity caused by the auditory apparatus, brain and the nerve. The basic makeup of the auditory organ and its functions are stated in the paper. The auditory mathematics model is built to analyze the frequency decomposition of cochlea, the energy exchange of hair cell and the character pick-up of nerve net. The theory is used to explain why bats can hear ultrasonic. |
