Hearing Flashcards
The malleus is part of the
middle ear
Which can be characterized as primarily an impedance matching devices
middle ear, the ossicular chain
The nonlinear frequency response of the cochlea means that mammals are
more sensitive to differences at low frequencies than very high frequencies

Place theory
different regions of the basilar membrane is sensitive to different frequencies
Frequency Theory
Neurons fire when they are stimulated by a periodic sound
A spectrogram
displays acoustic energy across time and frequency

like a spectrogram that is adjusted for how sound is received by cochlea
Conductive hearing loss
problem with sound transmission
Sensorineural hearing loss
includes damage to hair cells in cochlea, damage to the auditory nerve
