A dominant view holds that the outer and middle ear are the determining factors for the frequency dependence of mammalian hearing sensitivity, but this view has been challenged. In the ensuing debate, there has been a missing element regarding in what sense and to what degree the biophysics of the inner ear might contribute to this frequency dependence. Here, we show that a simple model of the inner ear based on fundamental physical principles, reproduces, alone, the experimentally observed frequency dependence of the hearing threshold. This provides direct cochlea modeling support of the possibility that the inner ear could have a substantial role in determining the frequency dependence of mammalian hearing.
一种主流观点认为，哺乳动物听力灵敏度的频率依赖性取决于外耳和中耳，但这一观点受到了挑战。在随后的争论中，人们忽略了一个问题，即内耳的生物物理学在何种意义上以及在何种程度上可能对这种频率依赖性有贡献。在这里，我们展示了一个基于基本物理原理的内耳简单模型，它单独再现了实验观测到的听力阈值的频率依赖性。这为内耳在决定哺乳动物听力的频率依赖性方面可能具有重要作用的可能性提供了直接的耳蜗建模支持。
