哺乳动物耳蜗作为物理引导进化优化的听觉传感器

Mammalian cochlea as a physics guided evolution-optimized hearing sensor

Tom Lorimer, Florian Gomez, Ruedi Stoop

摘要:

非线性物理学在听觉中起着至关重要的作用,从声音信号产生到声音感测再到复杂声音环境的处理。我们证明了生物听觉传感器的发展表明,由于非线性物理原理,听觉传感器可用的解决方案空间急剧减少。更具体地说,我们的分析提示,羊膜谱系听力之间的差异,可以被重新塑造成一个可缩放和不可缩放的非线性声音探测器的安排。作为最先进的设计,在哺乳动物中采用的可扩展解决方案提供了一个自然的背景,需要通过音高对复杂声音进行最终表征。

英文摘要:

Nonlinear physics plays an essential role in hearing, from sound signal generation to sound sensing to the processing of complex sound environments. We demonstrate that the evolution of the biological hearing sensors demonstrates a dramatic reduction in the solution space available for hearing sensors due to nonlinear physics principles. More specifically, our analysis hints at that the differences between amniotic lineages hearing, could be recast into a scaleable and a non-scaleable arrangement of nonlinear sound detectors. The scalable solution employed in mammals, as the most advanced design, provides a natural context that demands the ultimate characterization of complex sounds through pitch.
