For 100-Hz to 6000-Hz sound stimuli, basilar membrane has electric pulses, with same frequency and intensity, caused by potentials from all hair cells, that do not fatigue.
For 20-Hz to 900-Hz sound stimuli, auditory-neuron axons have electric pulses {microphonic electric pulse}, measured in cochlear nerve, with same frequency and intensity [Saul and Davis, 1932]. For 900-Hz to 1800-Hz sound stimuli, auditory-neuron axons have electric pulses with same frequency and one-half intensity. For 1800-Hz to 2700-Hz sound stimuli, auditory-neuron axons have electric pulses with same frequency and one-third intensity. For above-2700-Hz sound stimuli, auditory-neuron axons have electric pulses that do not correlate with frequency and intensity. Perhaps, auditory nerve uses summed potentials of microphonic-electric-pulse envelopes.
