摘要: Publisher Summary This chapter explains that frequency selectivity measured behaviorally in masking experiments, is largely determined by the filtering occurs on basilar membrane (BM). The tuning of a specific point BM two components: passive component reflecting hydromechanical properties and surrounding fluids structures, an active influence outer hair cells (OHCs) motion. appears to be roughly linear does not vary with level, while highly nonlinear. nonlinearity greatly complicates analysis interpretation experiments. presents simple model ignores these complications, further discusses. power-spectrum concept critical band,. various excitation patterns. A major difference between simultaneous nonsimultaneous revealed greater than masking. well-studied example this PTC. PTCs forward are typically sharper those obtained
