Question:
1. What is the LTASS?
Answer:
Long-term average speech spectrum.
Question:
2. What is the dynamic range 30 dB
Answer:
of the LTASS in dB?
Question:
3. The LTASS is also known as The speech banana. (It is just replotted in dB HL on the audio-
Answer:
what other well known au- gram.)
diology tool?
Question:
4. Reverberation is the time it 60 dB
Answer:
takes for reflected sounds
to die down by how many
dB from cessation of the
source sound?
Question:
5. What signal-to-noise (SNR)
is needed for satisfactory
communication?
Answer:
+6 SNR
,Question:
6. Potential advantage of bin-
aural hearing aid fitting.
Answer:
Elimination of the head shadow ettect (10 to 15 dB attenuation of
sound, mostly high frequency, by the head when sound arrives
from contralateral side.
Question:
7. What are some advantages
of doing a binaural fitting
versus a unilateral hearing
aid fitting?
Answer:
1) decreases head shadow ettect,
2) loudness summation (2 - 8 dB, depends on many factors),
3) improved sound localization,
4) binaural redundancy,
5) binaural squelch
Question:
8. What are a few advantages
of CIC hearing aids?
Answer:
1) cosmetics,
2) preservation of sound localization,
3) reduce wind noise,
Question:
4. natural pinna ettects,
5) some high frequency benefit >2000 Hz.
Answer:
Question:
9. What are some drawbacks
to CIC hearing aids?
,Answer:
1) dexterity/vision concerns, 2) size 10 battery (life/size), 3) no
directional mics, telecoils
Question:
10. What hearing aid can be
placed in the ear for ex-
tended periods and how
long is the time it can stay
in the canal?
Answer:
The Lyric IIC is an extended wear aid that must be inserted by a
professional and can remain in the canal for three to four (3-4)
months.
Question:
11. What are potential benefits
of bilateral hearing aid fit-
tings?
Answer:
1) elimination of head shadow ettect, 2) loud summation, 3) sound
localization, 4) improved speech in noise perception
Question:
12. How much attenuation oc- 10 - 15 dB attenuation of sound, mainly in high frequencies
Answer:
curs from the head shadow
effect and in what frequen-
cy range?
Question:
13. What dB of benefit comes
from loudness summation?
Answer:
2 - 8 dB depending on various factors
, Question:
14. Why is speech in noise per- There is a 2 to 3 dB better SNR with bilateral fitting due to binaural
Answer:
ception improved with a bi- redundancy and binaural squelch
lateral fitting?
Question:
15. What are some potential
contraindications to binau-
ral fitting of HA's?
Answer:
1) degree of hearing loss, 2) cost, 3) convenience, 4) binaural
interference, 5) perceived benefit
Question:
16. What are the two prima-
ry concerns/considerations
Answer:
1) acoustic feedback, 2) occlusion ettect
when fitting any hearing
aid?
Question:
17. When one takes measures
to decrease feedback, what occlusion ettect)
other problem can then
arise?
Answer:
Occlusion ettect (sometimes you have to balance b/t feedback &
Question:
18. Describe the occlusion ef-
fect.
Answer:
It is an increase in low frequencies (generally <500 Hz.) that
occurs when the ear canal is occluded that causes a "hallow" or
"booming" sound in the ear when the client talks or chews.
