Anatomy & Physiology
Cochlea is in this part of the ear
Inner
< sits between 0-25 dB HL across the board
O sits between 50-60 dB across the board.
What type of hearing?
Conductive
I have wax occluding my ear. What type of type of tymp would I have?
Type B - small ECV
Best for someone with no ear canal
BAHA
X axis of an Audiogram
Frequency / Pitch
This is an involuntary response to loud sounds
[ sits between 50-60 dB HL across the board
X sits between 50-60 dB across the board.
What type of hearing?
Sensorineural
No peak pressure, no compliance, large volume. What type am I?
Type B tymp
Best for mild to severe hearing loss where the inner ear still functions.
Hearing Aid
These symbols: < > [ ] indicate which type of response
Bone conduction
Peripheral Auditory System (outer, middle, inner ear and auditory nerve) is embedded where
Temporal Bone
This type of hearing indicates a problem with the cochlea or auditory nerve.
Sensorineural
Negative pressure, normal compliance, and normal volume. What type am I?
Type C tymp
Provide hearing for people with severe to profound sensorineural hearing loss, and limited benefit from hearing aids.
Cochlear Implant
Insert earphones deliver this type of signal
Air conduction
The purpose of this part of the ear is to make up for lost energy
Middle ear
Indicates a problem in both the auditory nerve or cochlea and outer or middle ear systems
Mixed
Low compliance, normal volume, normal pressure. What type am I?
Type As
This device converts sound to vibrations through the skull and into the cochlea. Bypasses the outer/middle ear.
BAHA
Under this word recognition score, would qualify for cochlear implant evalution
60%
The way the cochlea is organized
Tonotopically
A hole in the ear drum would cause this type of hearing loss
Conductive (or mixed)
this type of tymp would be present with a sensorineural hearing loss
Type A tymp
Improves listening in specific situations by enhancing the signal-to-noise ratio.
ALD
2 Types of speech testing commonly performed
SRT and WRS
