auditory physciology
detech frequencieds from 20 hz to 17000
most sensitive 1000-3000
pain at 120 dB and 80dB is bad
low frequency is timing based as wavelength goes around the head
highfrquency is volume based as head blocks wave
as the cochlea is water ne ustilise 2 mechanisms to amplify noise
the lever action of the ear bones
the area of tympanic membrane vs cochlear
otitis media - middle ear infeciton
