AbstractCTS-0132695M. Yoda, Georgia Institute of TechnologyThe objective of this SGER proposal is to study steady streaming flows due to oscillating bluff bodies of complex shape in highly confined fluid geometries. It is hypothesized that fish determine the direction of incident sound by exploiting such flows in their inner ears. If proved to be correct, this "auditory retina" hypothesis could lead to a new paradigm in sensory biology with possible application in human hearing. In engineering practice, this hypothesis could lead to compact and sensitive underwater acoustic transducers.

abstractcts - 0132695 m。这个SGER提案的目标是研究在高度受限的流体几何形状中由复杂形状的振荡钝体引起的稳定流动。据推测，鱼类通过利用内耳中的这种气流来确定入射声音的方向。如果被证明是正确的，这种“听觉视网膜”假说可能会导致感觉生物学的新范式，并可能应用于人类听力。在工程实践中，这一假设可以实现紧凑、灵敏的水声换能器。
