Q

List the components of a HA and what each one does.

A

Q

Define the Occlusion Effect.

A

When LF sounds get trapped in the back of our throats, but HF sounds move to our mandible via BC, but turn into AC due to vibrations of low frequency sound of the cartilaginous portion of the ear canal. Since a hearing aid is present, LF sounds cannot naturally escape, so the trapped sound is reflected back to our eardrum and transmitted to our cochlea via AC. Thus enhancing the sound the person hears.

Q

List advantages of BTE

A
  1. It’s design, earmold, tubing, and earhook can all be used to modify frequency response of a signal
  2. Microphone port is near TM and the HA is positioned on top of the pinna so this allows for directional cues
  3. Larger sizes allow for various technologies
  4. Great for children still growing
  5. Improved durability due to separation of electronic components

A

They are both hard to modify

24
Q

List one con for Silicone & Vinyl

A

Silicone: Harder to insert

Vinyl: Less durable

25
What is the benefit of a custom HAs?
Improves directionality due to Pinna Effect
26
List benefit of BTE/RIC.
1. Multiple coupling options 2. Wide fitting range 3. Rechargeable 4. Wireless compatibility
27
When would you consider BAHA
1. CHL | 2. SSD
28
When would you consider a CROS v BiCROS?

29
What are the EM styles?

31
Which freq does venting affect?
Low
32
What are the types of Acoustic Venting Options?

Allow LFs sound to leak out of the ear
34
When would we consider a Side Branch vent option?
To cut HFs
35
When would we consider Trough vent option?

37
What does open domes aid in?
1. Allows for some natural noise to enter EC | 2. Allows some LFs to dissipate
38
What does closed domes aid in?
1. Block more of the ear canal | 2. Amplify LFs
39
What type of HL does open domes benefit?
Mild-Moderate HL
40
What type of HL does closed domes benefit?
Moderate HL
41
What type of HL does power domes benefit?
Severe-Profound HL
42
What does power domes aid in?
1. Full seal around ear canal | 2. Maximum sound amplification with minimal sound dissipation
43
What is the goal of dampers?
To smooth out the peaks in frequency response of the HA that leads to acoustic FB or poor sound quality
44
When would we typically use dampers?
For BTEs with earhook
45
Dampers focuses on which frequenies?
Mid
46
Horn effect focuses on which frequency?
HF
47
What does a horn effect do?
Change the shape of the sound bore to either increase or decrease HF
48
A Horn would ...
Increase HF
49
A Reverse Horn would...
Decrease HF
50
What are the consequences of untreated HL?
