ear canal and middle ear transfer
function boosts signals around this Type I Auditory Nerve Fibers
frequency

Term
Why should noise affect 4 kHz more severely compared to other
frequencies?
Give this one a try later!
ear canal and middle ear
noise at lower frequencies is more
transfer function boosts
damaging to hearing
signals around this frequency
the ear's natural resonance the human ear is less sensitive to
diminishes at 4 khz higher frequencies

Term
T/F: Zero dB SPL is when there is no sound

False Zero
OAEs True
Don't know?
4 of 259
Term
If a sound is too loud, the brain sends a message to the middle ear
muscles to tighten. Using the formula f = square root of (k/m), explain
which frequencies would be attenuated in this scenario.
Give this one a try later!
Meniere's Disease
, The different neurons in the cochlear nucleus perform different types of
processing. Such processing will be maintained if they are stimulated by the
auditory nerve using a CI, but stimulating the cochlear nucleus directly may not
retain such the varied processing, and replicating the different neural responses
is very difficult.
low frequencies because as stiffness increases with the inner ear muscles
duo does frequency, meaning higher frequencies would be preferentially
let through
No, they are processed at different places on the BM (talk about 18 kHz tone
being high frequency and 1 kHz tone being low frequency)
Don't know?

Definition
-Scala vestiboli, scala media scale tympani
-Reissner's membrane, sectoral membrane, basilar membrane,
reticular lamina
-Stiff base of cochlea, flaccid apex of cochlea
Give this one a try later!
3 Orders of anatomy:
