in which the location of MAXIMAL VIBRATION is frequency
dependent
What is the instantaneous basilar membrane pattern? - ANSWERS-
Position of basilar membrane one instant in time
What is the envelope of the traveling wave? - ANSWERS-Estimate of
overall pattern basilar membrane vibration over a fairly long period of
time
