A patient who recently had a stroke with a permanent limited use of one
arms presents with a symmetrical hearing loss. He also reports a history
of excessive wax requiring routing cleanings. What should the hearing
healthcare professional recommend?
Synchronization w core DSP
A patient who recently had a stroke with a permanent limited use of one
arms presents with a symmetrical hearing loss. He also reports a history
of excessive wax requiring routing cleanings. Which two features should
be considered when selecting the proper hearing solution for this
patient?
Directional mic w adaptive compression, and multi-memory.
Which two of the following are acceptable to use as part of the
complete hearing evaluation?
NU 6 and CID W-22
A hearing healthcare professional is counseling a patient about learning
how to re-train the brain to listen with a hearing aid. What important fact
should be explained the the family/caregiver?
Hearing impaired have listening habits to overcome
,The bending of waves around obstacles- e.g. sound waves producing
head diffraction. (around the head).
Diffraction
Various components all populated into a tiny wafer of silicone helps
miniaturize electrical energy from the microphone and is amplified and
modified by the IC
Integrated circuit aka IC
2 multiple choice options
speech UCL + 20db typically; or pure tone LDL between 2k and 3k +
10db
maximum OSPL output formula
abnormally acute hearing due to heightened irritability of the sensory
and/or neural mechanisms. bothered by moderate or even soft sounds
hyperacusis
RECEIVE info FROM the brain. they amplify soft sounds in the cochlea
outer hair cells
1 multiple choice option
10 ^ -16 watts/cm^2 and pressure of .0002 dynes/cm^2
faintest sound a human can hear
,transitor using magnetic microphones (sufficient in speech freq and
durable) 1964, omnidirectional
ITE custom
narrowest pass-way between scala vestibule and scala tympani
helicotrema
Narrowing of ear canal
Stenosis
3 multiple choice options
used in almost all aids today!
electret microphone
impede low freq and pass the highs (like resistors, also measure in ohms)
capacitor
distorted speech. aud deprivation
auditory neuropathy
Is used in audiology to detect and measure auditory fatigue, behavioral
test
Tone decay test
, about 3k-4k / ear. they are afferent - SEND info TO the brain
inner hair cells
tumor on auditory nerve. can be life-threatening. symptoms: large,
unexpected AN asymmetries, WR poorer than expected, recent onset of
unilateral tinnitus, dizziness.
acoustic neuroma
Single channel with adaptive memory
class 2 programmable hearing aid
1 multiple choice option
above audible range of 20K Hz
ultrasound
1 multiple choice option
-150 to +25 daPa
normal pressure values of TM (the force it takes)
