Critical Bandwidth and the Frequency Coordinates of the Basilar Membrane

摘要: Masked audiograms were used to measure critical bandwidth. On the assumption that bands represent equal distances on basilar membrane and bandwidth increases exponentially with distance from helicotrema, functions derived which (1) relate frequency position (2) of maximum amplitude frequency. The are consistent Bekesy's optical observations Mayer's psychophysical data. frequency‐position function is f = A (10ax − 1). coefficient a numerically identical in exponential fitting elasticity Functions this form fit data seven other species values seem related their respective elasticity, interpretation as interval over cochlea sums power supported by Mayer, hypothesis dis...
