SHS 430 Exam 1: Questions & Detailed SolutionsAudiogram Right Ans - a graphic display of audiometric data
> Right Ans - bone conduction for the left ear
< Right Ans - bone conduction for right ear
X Right Ans - air conduction for the left ear
O Right Ans - air conduction for the right ear
behavioral audiometry Right Ans - pure tone testing under earphones or
with inserts or wave tone/narrow band noise in the sound field
speech reception threshold Right Ans - two syllable word (spondee words)
are presented; a down 10 up 5 threshold search is completed until 50%
criteria at minimal intensity is achieved
speech discrimination/ word recognition Right Ans - one syllable,
phonetically balanced words are used; a word is given for the patient to
repeat
tympanometry Right Ans - a general assessment of middle ear function; a
probe tip is inserted in the ear canal and pressure is varied
a tracing of tympanometry is called Right Ans - tympanogram
Type A Right Ans - normal
Type B Right Ans - flat, generally means effusion if the volume is normal
Type C Right Ans - negative pressure
otoacoustic emission testing Right Ans - test of cochlear function,
specifically the outer hair cells
, TRUE Right Ans - True/false
otoacoustic emission testing cannot qualify a hearing loss and does not look at
structures beyond the cochlea
auditory brainstem response Right Ans - This test stimulates the VIII
cranial nerve acoustically and the nerve gives off a typical signature response
if it is working properly and peripheral hearing is intact.
conductive Right Ans - involves the pinna, external ear canal, eardrum
(TM), middle ear ossicles & muscles, and middle ear cavity.
TRUE Right Ans - true/false
A purely conductive problem assumes that there is nothing wrong with the
cochlea or the auditory nerve
sensorineural Right Ans - problems with the inner ear (cochlea) or along
the nerve pathway from the cochlea to the brainstem
TRUE Right Ans - A pure SNHL is present when the entire conductive
mechanism is normal.
Characteristics of SNHL Right Ans - 1. child may talk louder than normal
2. poor word recognition
3.may be unusually sensitive to loud sounds
sensory loss Right Ans - occurs within the cochlea and is usually due to
damage to hair cell structures or lack of development. Very common. Noise
induced or ototoxicity are common causes. Usually accompanied by tinnitus.
Almost, always permanent.
neural Right Ans - problem with VIII nerve or auditory pathways, normal
cochlea (will have OAEs), can be secondary to acoustic neuroma.
mixed hearing loss Right Ans - some elements of both conductive and SNHL
central processing disorder Right Ans - individuals have difficulty utilizing
the auditory information that is provided by a relatively intact or normal
peripheral mechanism
