Part 3.4 Flashcards
Eight words are missed on a complete list of PB words. the score is…
a) 84%
b) 92%
c) 64%
d) 32%
a) 84%
How many words are on a PB list? It becomes a straight math problem.
Doubling sound pressure does what?
a) Increases decibels by 10
b) Increase 6
c) Increases decibels by 2
d) Does not significantly affect decibels
b) Increase 6
Straight memorization. The sound pressure level falls by 6 dB every time the distance between the source and the listener is doubled. Reverse this datum to understand the question.
An abnormal sensation to loudness growth is associated with the term _____?
a) Tinnitus
b) Presbycusis
c) Meniere’s disease
d) Recruitment
d) Recruitment
An adaptive directional microphone hearing aid _____?
a) Changes from omni to directional mode
b) Changes the polar pattern according to the noise source
c) Has been shown to be more effective than a fixed directional microphone for speech understanding
d) Is not affected by reverberant noise
b) Changes the polar pattern according to the noise source
A BILL processing strategy _____?
a) Restricts low frequencies as intensity levels increase
b) Restricts high frequencies as intensity levels increase
c) Restricts low frequencies as intensity levels decrease
d) Is prevalent in linear hearing aids
a) Restricts low frequencies as intensity levels increase
Low frequencies are bass, as in Bass Increase at Low Levels. Visualize what this means.
Recruitment is best defined as
a) a small increase in sound intensity resulting from rapid increase in apparent loudness
b) a high frequency ringing or buzzing noise
c) an hallucination of movement, arising from problems within the vestibular system
d) a change in the stiffness or compliance of the basilar membrane, or fixation of the stapes
a) a small increase in sound intensity resulting from rapid increase in apparent loudness
Recruit is to pull in loud sounds, as in increased Intensity.
Loudness recruitment may be caused by
a) damage to the outer hair cells
b) loud noise exposure
c) ototoxic medications
d) all of the above
a) damage to the outer hair cells
Damaged hair cells still try to make up for what is lost.
The symptoms of otitis interna parallel those of _____?
a) non-suppurative otitis media
b) suppurative otitis media
c) myringitis
d) Meniere’s syndrome
d) Meniere’s syndrome
Otosclerosis of the cochlea is a _____ occurrence in the elderly population.
a) common
b) somewhat common
c) relatively rare
d) rare
c) relatively rare
The key here is knowing what otosclerosis really is.
Tympanoplasty is the
a) lansing of the eardrum
b) repair of the a perforated eardrum
c) removal of a cholesteatoma near the eardrum
d) placement of a PE tube in the eardrum
b) repair of the a perforated eardrum
Otosclerosis primarily affects
a) membranous tissue
b) bony tissue
c) fibrous tissue
d) mucous tissue
b) bony tissue
Otosclerosis is not predominately found in
a) Caucasian women
b) families
c) the elderly population
d) pregnancy
c) the elderly population
Typical weird question. Found in variety of young, but the question doesn’t pinpoint
In a mixed hearing loss
a) air conduction scores are normal, bone is reduced
b) air and bone are both reduced approximately the same
c) air and bone are both reduced, but there is an air-bone gap
d) bone scores are normal, but air is reduced
e) none of the above
c) air and bone are both reduced, but there is an air-bone gap
The Pure Tone Average is obtained by
a) averaging the response at 0.5, 1 and 2 kHz
b) averaging the response at all frequencies tested
c) using the same formula as for obtaining the DR
d) none of the above
a) averaging the response at 0.5, 1 and 2 kHz
A cholesteatoma is
a) an infection of the inner ear that can cause otitis internia
b) a tumor that can be found in the middle ear
c) a condition of the ear canal that may result in poor earmold fit
d) none of the above
b) a tumor that can be found in the middle ear
