Anatomy and Physiology
The 3 bones of the middle ear
What are the malleus, incus, and stapes
Lowest intensity at which a patient responds at least 50% of the time
what is a threshold
This is a test that evaluates middle ear pressure, volume, and compliance
What is tympanometry
This type of device would be appropriate for someone with very poor WRS
What is a cochlear implant
This is a noise that is presented to the non-test ear during audiometric testing via air conduction
What is a masker
The way the cochlea is organized
What is tonotopically
The X axis of an audiogram
What is frequency.
(and what scale?)
This test can be used for newborn hearing screenings
What are OAEs
This type of user refers to someone who wears a HA in one ear and a CI in the other
What is bimodal
This transducer is not ear-specific
What is Sound field speakers or BC oscillator
The part of the ear where the cochlea is
What is the inner ear
This is documented by the following symbol : < , [
What is Right bone conduction
This type of tympanogram has abnormally low compliance
What is type As
This provides awareness or identification of speech and environmental sounds and helps to improve the signal-to-noise-ratio (SNR)
What is an assistive listening device
This transducer can test frequencies above 8000 Hz
What are Circumaural headphones
The function of this part of the ear is to transduce mechanical signal into electrochemical activity
What is the inner ear
An air bone gap is present
Abnormal BC thresholds
Abnormal AC thresholds
What is mixed hearing loss
This is the normative ear canal volume for adults
What is 0.8 - 2.2
These are the 3 manufacturers for cochlear implants
what are Advanced Bionics, MedEL and Cochlear Americas
Presbycusis causes this type of HL
What is SNHL
This occurs when the stapedius and tensor tympani muscles contract
What is the acoustic reflex
This test scores the number of words correct at a supra-threshold level
What is Word Recognition Score (WRS)
This tymp may be present with disarticulation of the ossicular chain
What is type Ad
This type of measure determines the extent to which hearing-related disability has been reduced by an intervention
What is validation
BC threshold sloping from 30 -45
AC threshold sloping from 60 - 95
is this type and degree of HL
What is mod-severe to profound MHL
