AC HA Styles & Fitting Apps (2C)

Question 1

what are fitting considerations to keep in mind

Answer 1

Fitting range- can the style supply sufficient output?
Pinna effect- will the microphone placement enhance or reduce spectral cues?
Likelihood that the style will cause feedback or occlusion?
Wind noise-will the wind to produce turbulence inside the microphone?
Will the size of the patient’s ear canal limit the output or size of controls?
Will perspiration, cerumen, and humidity impact device function?

Question 2

smaller HA = ____ output (custom)

Answer 2

weaker

Question 3

what is the fitting range of a BTE

Answer 3

all degrees
variable vent size - normal to mild HL in lows & mild in highs
occluding mold - moderate to profound in lows to profound in highs

Question 4

is there a pe in bte? wind noise?

Answer 4

no
high wind noise
digital noise reduction in hign end producs

Question 5

feedback/occlusion in BTE

Answer 5

low
normal size ears cna have enough room to add large vents if needed

Question 6

are BTE effected by sweat or humidity

Answer 6

can be impacted by sweat
many come with high IP ratings
sweat can clog the tubing

Question 7

how can we change acousti parameters of a bte

Answer 7

by changing venting, damping and sound bore

Question 8

what is the fitting range of a slim tube (RITA)

Answer 8

mild to moderate hl
35-55dB hL

Question 9

what are the output limits of slim tube

Answer 9

HF output is limited by the soundbore & vent size

Question 10

pe or wind on slim tubes?

Answer 10

no pe
high wind noise
has digital noise reduction in high end products

Question 11

feedback or occlusion with RITA

Answer 11

can be reduced by non custom domes or large vents

Question 12

sweat and humidity of RITA

Answer 12

can be impacted by sweat
many come with high IP ratings
sweat can clog tubing
