IT'S ELECTRIC!
OH BABY!
LEND ME YOUR EAR!
SAY WHAT!
UNDER PRESSURE!
100
Refers to measuring the electrical activity of the brain and body.
What is auditory brainstem potential?
100
Testing performed on children in the soundfield ages birth to about 4-5 months. Presenting sounds and stimuli and watching the child for any change in behavior (i.e. eye widening, sucking, startle)
What is behavioral observation audiometry?
100
Provides an assessment of the functional integrity of the outer, middle, and inner ears via earphones or speakers.
What is air conduction?
100
Estimation of communication function, verification of pure tone audiometry, assistance in differential diagnosis, assessment of central auditory processing ability.
What is speech audiometry?
100
Sensitive in detecting middle ear disorders.
What is immitance audiometry?
200
Low intensity frequency specific sounds that are generated by the cochlea.
What are otoacoustic emissions?
200
Conditioning a child to turn their head toward a stimulus when a sound is heard.
What is visual reinforcement audiometry?
200
Establishing threshold sensitivity across the range of audible frequencies important for human communication.
What is pure tone audiometry?
200
The lowest intensity level at which 50% of spondaic words can be identified.
What is speech reception (recognition) threshold?
200
The extent to which the systen resists the flow of energy.
What is impedance?
300
These cells play an important role in the otoacoustic emission by producing a replication or echo of the sound which is received.
What are the outer hair cells?
300
Six to twelve months of age
What is when a child begins to turn their head towards a sound?
300
The temporal bone vibrates causing displacement of the cochlear fluid.
What is bone conduction?
300
A choice from a limited set or multiple choice (i.e. picture pointing).
What is a closed set?
300
When sound is of a sufficient intensitym it will eleicit a reflex of the middle ear muscles. This occurs 60-90dB above the threshold.
What is acoustic reflexes?
400
Synchronous firing of neurons and many neurons firing.
What is necessary in order to get the auditory brainstem response?
400
Delayed speech and language and higher incidence of CAPD and learning disabilities.
What is the effects of otitis media and its impact on communication?
400
The number of decibels lost in the crossover.
What is interaural attenuation?
400
A decrease in word recognition ability with an increase in intensity. This is suggestive of retro-cochlear sit of lesion.
What is rollover?
400
A common cause of middle ear disorder is a faulty Eustacian tube which cause a pressure difference between the middle ear space relative to the pressure in the ear canal, retracting the eardrum inward.
What is a Type C tympanogram?
500
Has a large amplitude, stability, and occurs on or near the threshold of hearing.
What is Wave V of the ABR?
500
Auditory perceptual problems as a result of impaired central auditory nervous system; problems result in difficulty hearing in background noise.
What is central auditory processing disorder?
500
Modified Hughson-Westlake procedure
What is the procedure we use when finding threshold for pure tone audiometric testing?
500
Speech signals contain a wealth of information due to phonetic, phonemic, syntactic, and semantic content and rules. This allows us to hear only a part of a speech signal and still understand what is being said.
What is extrinsic redundancy of speech?
500
Anything that causes the ossicular chain to become stiffer than normal can result in reduction in energy flow through the middle ear.
What is a Type As tympanogram?
