Exam 3 Flashcards
Most modern types of hearing aid circuits are this kind.
Digital
The difference between the intensity of the input signal and intensity of the output signal in a hearing aid is _______ _______
Acoustic gain
CROS hearing aids were originally designed for people with what type of hearing loss?
Unilateral
A whistling sound from a hearing aid
Feedback
An induction coil built into hearing aids that pick up electromagnetic signals from a telephone
telecoil
measurement of middle ear pressure
tympanometry
The cranial nerves involved with the acoustic reflex arc _______ & ___________
VII & VIII
Otoacoustic emissions may be either stimulated or _______
evoked
True or False: ABR is an exact measure of hearing
False
Observation of changes in the activity state of an infant in response to sound
Behavioral observation audiometry
The use of a light or picture to reinforce a child’s response to sound
Visual reinforcement audiometry
Testing hearing by having the child put a peg on a board or a block in bucket, or….
Conditioned play audiometry
A form of operant audiometry using tangible reinforcers such as food or tokens
Tangible reinforcement operant conditioning audiometry
The main goals of infant hearing screening
Early identification and intervention
The falsification or exaggeration of hearing ability for some conscious or unconscious reason
Erroneous hearing loss
This “classic” test is best used for people who have asymmetrical hearing losses
Stenger Test
treatment of adults who have hearing loss
audiological rehabilitation
treatment of children who have hearing loss
audiological habilitation
Americans with Disabilities Act
A public law to provide equal opportunity for individuals who have disabilities
Public Law 94-142
Education for All Handicapped Children Act
Annually-updated, federally mandated plan for the education of children who have handicaps
Individual Educational Plan
This type of hearing loss is almost always preventable
Noise induced
The song that was played in class
“Turn It To The Left”
Type of hearing loss in which both air conduction and bone conduction are equally impaired
sensorineural
This measure is on the horizontal axis on an audiogram
Frequenzy (Hz)
This measure is on the vertical axis on the audiogram
Intensity in decibels
The indication of an unmasked threshold for the right ear
O
What you obtain before practicing audiology
A state license
Abnormally high static compliance suggests
A fracture in the ossicular chain or a flaccid tympanic membrane
No compliance of the tympanic membrane in children is often caused by this
Middle ear fluid
if a person has a normal tympanogram, what type of hearing would that person have?
Normal hearing or sensorineural hearing loss
If a person has normal hearing in both ears, during acoustic reflex testing a signal presented to the left ear will elicit a reflex in the right ear, left ear, or both ears?
Both.
If a person has a normal evoked OAE, is that a guarantee of normal hearing?
NO
A patient with a severe sensorineural hearing loss with normal otoacoustic emissions is expected to have a lesion of what?
VIIIth nerve
Response to the sound in the form of electrical potentials that occur within the first few milliseconds after signal presentation
electrocochleography
In this test, waves are identified within the first 10 milliseconds
ABR
The tests often used in newborn hearing screening programs
OAE & ABR
Since many children do not respond at threshold during auditory tests, their responses are often called
Minimal response levels
Apgar is a procedure for evaluating
Newborns in the hospital
If otoacoustic emissions are present, hearing loss is no greater than
mild
Nonverbal children may be tested using speech audiometry by having them
Point to named pictures
What does the child need to do for an ABR test?
Remain still and quiet
Difficulty in the development of language and other communication skills associated with disorders of the auditory centers in the brain
Auditory processing disorder
The deliberate act of pretending to have or exaggerating a disability to personal gain
malingering
An erroneous hearing loss with root at an unconscious level
psychogenic
One of the first symptoms of erroneous hearing loss
Discrepancy between the pure tone average and the speech recognition threshold
A person may have normal hearing in one ear and no hearing in the other
Crossover should be noted in masking was not used
These types of tests require no response from the person being tested
Objective (acoustic reflex, OAE, ABR, etc)
Without objective testing, we may not know the person’s true hearing
The two things that affect how dangerous a sound is
Duration of exposure
Intensity of the sound
These types of devices are usually reserved for those with profound hearing loss
Cochlear implants
The event-related potential is also called the
P300
Theoretically, a patient with otosclerosis should show
lower than normal tympanic membrane compliance.
A patient has a 40 dB hearing loss caused by otosclerosis in the left ear. Acoustic relfexes with contralateral stimulation would probably show
absent right, absent left
Absence of an acoustic reflex is probable in
conductive hearing loss
facial nerve paralysis
profound sensorineural loss
During ABR the average electrical response is
1-5 microvolts
