On the Resonance Curve and the Decay Period at Various Points on the Cochlear Partition

摘要: In order to determine the way in which mechanical analysis of frequency occurs cochlea, a technique was developed for preparing anatomical specimens. This made it possible measure amplitude vibrations along cochlear partition when stapes driven with pure tones. It possible, further, how vibration at any given place on varies frequency. The relation gives curve very similar resonance curve. We can then calculate logarithmic decrement characterizing partition. log is almost independent and has value d = 1.3. decay time observed directly microscope, values obtained this agreed those derived from curves. All measurements have been preparations human ear.
