【摘要】：耳蜗力学是听觉科学和生理声学研究的核心话题,同时也是一个极具代表性的生物力学话题.深入总结和揭示耳蜗力学特性能够推动相关问题的深入研究和促进心理声学的发展与应用.该文分宏观力学和微观力学两部分进行综述,然后结合近几年的研究动态,总结耳蜗力学的发展趋势和应用前景.表明耳蜗作为一个杰出的频率选择和高灵敏度的声信号感应器官,可以对20~20000Hz这样跨度达千倍的频率做出精确响应,且刺激信号可以放大4000倍以上.
[Abstract]:Cochlear mechanics is a central topic in auditory science and physiological acoustics. At the same time, it is also a representative topic of biomechanics. Summarizing and revealing the mechanical properties of cochlea can promote the development and application of psychoacoustics and promote the development and application of psychoacoustics. This paper is divided into macro mechanics and micro force. The two parts of the study are summarized, Then combining with the recent research trends, the development trend and application prospect of cochlear mechanics are summarized. The results show that cochlea is an excellent frequency selective and highly sensitive acoustic signal sensing organ. It can be used to accurately respond to the frequency with a span of 20 ~ 200Hz and amplify the stimulus signal by more than 4000 times.
