What do the different symbols on the audiogram represent?
Red < = right ear bone conduction
Blue > = left ear bone conduction
Red O = right ear air conduction
Blue X = left ear air conduction

When using a cochlear implant, there is often a loss of low frequency information. Why is this?
The cochlea is incredibly small, and the electrodes of the CI can't get all the way to the apex of the cochlea.

Why would somebody need a Stapedectomy?
If they have Otosclerosis--an abnormal bone growth that causes the stapes to become stuck in place.
Stapedectomy = a surgery where all or part of the original stapes bone is removed and replaced it with an artificial device (prothesis)

What middle ear structure explains why my ears "pop" on an airplane?
Eustachian Tubes EQUALIZE PRESSURE inside of middle ear to the "outside world".

What do we call the little structures sitting right on top of the hair cells (we have about 50 on top of each inner hair cell and about 150 on top of each outer hair cell)
Stereocillia

Bone conduction bypasses the _____ and _____ ear by sending sounds right to the _____ via vibration in the skull, using a bone oscillator.
Bone conduction bypasses the outer and middle ear by sending sounds right to the cochlea (in the inner ear) via vibration in the skull, using a bone oscillator.
400
T/F: The more electrodes used in a cochlear implant, the better the sound quality.
TRUE. The actual sound of a CI depends on the number of channels in the electrode array.
More electrodes = more fine-grained differentiation between frequencies (see YouTube video from lecture).
