What is static compliance?
How high the peak is
100
SRT should be in agreement with the _______ within _____dB HL.
PTA 10
100
Describe what happens to the muscles and bones of the ear during acoustic reflex
Contraction of the stapedius muscle pulls on the stapes while contraction of the tensor tympani pulls on the malleus and stiffens the auditory system
100
What are risk factors for otitis media?
Cigarette smoke Allergies Feeding position Breastfeeding
100
What are disorders of the external auditory meatus?
Aural Atresia Otitis Externa Collapsing Ear Canals Impacted Cerumen
200
In a type B tympanogram, what measure is especially important?
Volume
200
Stimuli used in SRT are called what?
Spondee words
200
Characteristics of a conductive hearing loss
Usually temporary Can usually be treated medically or surgically Simply reduces the volume of signal Maximum loss of 60 dB
200
List symptoms of Meniere's Disease
Vertigo Aural fullness Fluctuating unilateral SNHL Poor speech discrimination Roaring tinnitus
200
What is otosclerosis?
A middle ear disorder characterized by the fixation of the ossicles.
300
A type B tympanogram with a high ear canal volume may be indicative of...?
Pressure equalizing tubes
300
What is the formula to calculate SRT?
Starting level (dB HL) – words correct + 2 dB
300
Characteristics of a sensorineural hearing loss
Usually permanent Usually cannot be treated medically or surgically Reduces volume of signal AND reduces clarity of signal (i.e., reduced frequency resolution) Can range from mild to profound
300
What medications an lead to Ototoxicity?
Chemotherapy (cisplatin, carboplatin, etc.) Antibiotics (gentamycin, streptomycin, etc.) Megadoses of aspirin, nicotine, diuretics
300
What are 2 disorders of the auricle?
Aural Microtia Aural Anotia
400
A type B tympanogram with normal Ear Canal Volume may indicate what?
Fluid
400
Why is MLV unreliable?
Intertalker reliability Intratalker reliability
400
Why are OAEs useful?
OAEs are pre-neural events from the cochlea - their measurement helps us to distinguish between sensory and neural hearing loss in some cases OAEs can be measured objectively in quiet patients in less than 1 minute per ear OAEs are essentially non-invasive OAEs are repeatable and reliable
400
What is presbycusis?
Auditory system structures degenerate with age.
400
Meningitis usually results in what?
complete deafness
500
What is the purpose of Immitance Testing?
Helps determine middle-ear function by indirect measurements made in the plane of the tympanic membrane
500
What is SDT?
Lowest hearing level at which a patient can barely detect the presence of speech
500
Describe the importance of latency related to a waveform analysis
What is measured is the latency of the waveform. Latency is where they occur in time.
