Audiological Evaluation
100
This is a low-intensity noise that is made by the outer hair cells of the inner ear.
What are otoacoustic emissions?
100
This is a benign tumor on the auditory nerve.
What is an acoustic schwannoma?
100
True/false: ABR is not used as a part of infant hearing screening.
False.
100
This uses broad band clicks to elicit a cochlear response.
What is transient evoked OAE?
100
These are four types of objective evaluations.
What are: tympanometry, acoustic reflex testing, OAE, and evoked potentials.
200
These are two negatives of otoacoustic emission testing.
What are: cannot determine degree of hearing loss or amount of cochlear damage.
200
Electrocochleography
What is summating potentials from hair cells and action potentials from the auditory nerve
200
This is used to differentiate between cochlear and retrocochlear pathologies.
What are physiological measures?
200
This is the reason for infant hearing screening.
What is early intervention is important in successful intervention outcomes?
200
Acoustic Immittance testing examines this.
What is how sound is transmitted through the outer and middle ear?
300
True/False: Outer hair cells can reversely transmit sounds.
True.
300
Electrocochleography
What is to monitor cochlea and auditory nerve function during surgery and to monitoring Meniere’s Disease.
300
This test is the only thing stronger than ABR for determining auditory pathologies.
What is magnetic resonance imaging (MRI) with contrast dye.
300
This form of testing should only be used for infants.
What is electrophysiological testing?
300
These are three types of acoustic immittance testing
What are: tympanometry, acoustic reflex threshold, and acoustic reflex decay?
400
This uses two pure tones to elicit another tone from the cochlea.
What is distortion product?
400
ABR produces a waveform obtained from synchronous neural firing. The five waves are generated from:
Waves I & II: auditory nerve, Wave III: cochlear nucleus, Wave IV: superior olivary complex, Wave V: lateral lemniscus and inferior collicus.
400
Behavioral site of lesion evaluation aims to determine this.
What is the anatomical site of lesion (cochlea vs retrocochlea)?
400
This type of hearing screening should be utilized in the case of a patient with a moderately severe sensorineural hearing loss, who otherwise presents with normal OAE.
What is ABR?
400
This can cause negative middle ear pressure.
What is Eustachian tube dysfunction?
500
List five conditions used to measure otoacoustic emissions:
1. No more than mild-moderate hearing loss. 2. Patient needs to be fairly still and quiet. 3. Clear outer ear. 4. Unaffected by sleep. and 5. Middle ear function has to be normal.
500
These are three types of site of lesion tests (describe as well).
What are: tone decay tests (test of tone adaptation due to reduction of neural response), loudness recruitment tests (the presence of loudness recruitment may indicate cochlea hearing loss), and difference limen tests
500
ABR was first identified in what decade.
What is the 1970s?
500
These are four possible outcomes of OAE testing.
What are: sensitivity, specificity, false negative, and false positive.
500
These are four clinical uses for acoustic immittance testing.
What are: identification of middle ear fluid, evaluation of EFE and CN VII & VIII function, assessment of integrity of ossicles and tympanic membrane, and determining the nature of hearing loss.
