Large frequency range of hearing
(50 Hz to 20,000 Hz)
Vast loudness range of hearing
(sound pressure varies by 106 from
threshold of hearing to threshold of pain).
HEARING
How can auditory system accommodate this range?
(Nerve signals are about 10 mV = 0.01 V. Multiplied
by 106 would require 10,000 V!)
Rather, nerves make fixed discharges (pulses)
whose time distribution reflects the tone you hear.
