Audiology Test 2
the three basic acoustic immitance tests are _____, _______, and __________ Correct Answer: static
acoustic compliance, tympanometry, acoustic reflexes
one dekapascal is equal to _____ Pascals Correct Answer: 10
abnormally high static compliance suggests Correct Answer: flaccid tympanic membrane or interrupted
ossicular chain
Type C tympanograms suggest Correct Answer: retracted tympanic membrane
the tympanograms of people with normal hearing may be identical to those of patients with _________-
hearing loss Correct Answer: sensorineural
acoustic admittance Correct Answer: tympanometric height
2 small muscles involved in the operation of the middle ear mechanism Correct Answer: tensor tympani
and stapedius muscle
intra- aural muscle reflex Correct Answer: most normal hearing individuals will demonstrate this
bilaterally when pure tones are introduced to either ear at 85 to 100 dB SPL
acoustic reflex threshold ART Correct Answer: lowest level at which an acoustic reflex can be obtained
the cranial nerves involved with the acoustic reflex are _______- and _______________ Correct Answer:
VII and VIII
assuming normal hearing in both ears, a reflex- activating signal presented in the left ear will elicit a
reflex in the right, left or both ears? Correct Answer: both
acoustic reflex thresholds of patients with cochlear hearing losses are expected to occur at ______
sensation levels. Correct Answer: low
extremely rapid acoustic reflex decay is expected of patients lesions of the Correct Answer: VIII cranial
nerve
otoacoustic emissions may be either spontaneous or Correct Answer: evoked
T/F a normal TEOAE does not guarantee normal hearing, and an absent TEOAE does not tell whether the
loss is conductive or sensorineural Correct Answer: true
, latency Correct Answer: used to define the time period that elapses between the introduction of a
stimulus and the occurence of the response
amplitude Correct Answer: strength or magnitude of a response
ECoG has been found to be useful during Correct Answer: neurosurgical procedures
a summing computer is used in ABR testing to help identify 7 small wavelets within the first
_________msec of the stimulus Correct Answer: 10
T/F the ABR is a direct test of auditory sensitivity Correct Answer: false
like the ABR, the ASSR is (affected or not affected) by the patient's state of consciousness Correct
Answer: not affected
loudness recruitment is suggestive of lesion in the Correct Answer: cochlea
tone decay Correct Answer: when the level of a tone is increased, the tone may be heard again, only to
disappear quickly to silence
patients with rapid tone decay often have lesions in/ on the Correct Answer: VIII cranial nerve
since many children do not respond at threshold during auditory tests, their responses are often called
Correct Answer: minimum response levels
apgar is a procedure for evaluating Correct Answer: newborns in the hospital
theauropalpebral reflex is a ____________ of the muscles around the Correct Answer: contraction, eyes
the main purposes of infant hearing screenings are and . Correct Answer: early identification, treatment
major advantages of using OAE's for infant hearing screening is that they are ___________ and
____________ Correct Answer: rapid, cost effective
if otoacoustic emissions are present, hearing loss is no greater than Correct Answer: mild
T/F a positive response to a broadband signal at essentially normal intensities indicates normal hearing
Correct Answer: false
most BOA procedures rely on a child's ability Correct Answer: to localize sound
a child with hearing loss and no co- existing handicaps can often be tested using behavioral audiometric
procedures before _________ years of age Correct Answer: three
nonverbal children may be tested using speech audiometry by having them Correct Answer: point to
named pictures or objects
OCA works best when the reinforcement is Correct Answer: tangible
