What's the AC threshold test frequency order? -
ANSWER-1000, 1500, 2000, 3000, 4000, 6000, 8000
re-test 1000, 750, 500, 250
* we re-test at 1000 because it establishes consistency
What's the BC threshold test frequency order? -
ANSWER-* present the initial tone 20 dB above AC
threshold
* re-established threshold
* ascend/descend method
What's the heliocatrema? - ANSWER-A semilunar opening
at the apex of the cochlea through which the scala
vestibuli and scala tympani communicate with one another
How do we know Interaural (between ears) attenuation
(reduction) is occuring based on audiogram results? -
ANSWER-IA attentuation varies per transducer and
frequency
1. Supraural - 40- 50 dB gap between left and right
thresholds at same frequency
,2. Insert- 50-70 dB gap between left and right threshold at
same frequency
3. BC oscillator - 0 dB gap because EVERYTHING
CROSSES OVER!
when the sound is presented at a high enough intensity
that the cochlea of the NTE hears the sound via BONE
CONDUCTION - ANSWER-Crossover
A method of masking the nontest ear in which masking is
introduced progressively over a range of intensity levels
until a plateau is reached, indicating the level of masked
threshold of the test ear - ANSWER-Plateau method
What's the psychological effect of frequency? - ANSWER-
Pitch! (Hz)
Physical measurement of cycles per second
- compression and rarefraction
What's the psychological effect of Intensity? - ANSWER-
Loudness (dB)
physical measurement of amplitude
Is the X axis horizontal or vertical? - ANSWER-horizontal -
Hz (frequency range)
,Is the y-axis horizontal or vertical? - ANSWER-vertical -
dB (intensity range)
What frequencies need to be tested for UCL pure tone
establishment? - ANSWER-1000, 2000, 3000, 4000 & 500
What's the inital pure tone given during AC testing? -
ANSWER-1000 Hz, 40 dB
What's the initial pure tone given during UCL testing? -
ANSWER-1000 Hz, 70 dB
The audiometric evaluation revealed several air-bone
gaps: 20 dB at 500 Hz; 15 dB at 1000 Hz; and 20 dB at
2000 Hz. This finding is called: - ANSWER-Red Flag
Latin name for:
Inward
&
Outward - ANSWER-inward- medial
outward - lateral
What is:
Anterior
Posterior
Lateral? - ANSWER-A - toward the front
P - toward the back
L - toward the side
, When does acoustic feedback occur? - ANSWER-
Whenever the receiver leaks sound that's p/u by the mic
and continously re-amplified by the HA
What are the 3 feedback sources? - ANSWER-1. Internal
(loose receiver/crack in shell)
2. External (excessive ceruman/imperfect seating in canal)
3. ear canal (imperfect seal)
How can you fix too much high frequency response? -
ANSWER-1. OVERALL gain reduction
2. decrease vent size
At times a binaural HL pt can only afford a 1 hearing aid.
How can you improve performance? - ANSWER-1.
directional microphones
2. reduce low frequency gain (less head in a barrel/hollow
sound)
What's the main focus when initially fitting a geriatric p/c? -
ANSWER-1. listening comfort and preference
** gain can be increased over time
WRS's can be explained as.... - ANSWER-Best Case
because they're meausred in a quiet environment
In establishing realistic expectations for potential hearing
aid wearers, it MAY be helpful to convey an estimate of
