Flashcards in unit 2 Deck (11):
1

checking hearing aids

use a hearing aid stethoscope
connects to their aid
think about what their loss is to understand what the aid should sound like
-missing the uppers- should sound like treble

2

using an otoscope

3/4 and younger use a peds tip
use adult for older

3

hearing aid

picks up sound (acoustic energy) with a microphone
transduced to mechanical energy to electrical to acoustic again
-an amplifier

A small electronic device that is worn in or behind the ear
It magnifies sound vibrations entering the ear making sounds louder and clearer for the user

4

digital vs. analog

analog is manually adjusted
digital is changed on a computer
digital is much clearer

5

types of hearing aids

behind the ear
in the ear
in the canal aids
completely in the cancel aids
implantable aids

6

behind the ear

ear mold and tube- putting as little in the ear canal as possible
traditional- power
-connected to an ear mold
-the bigger it is the more power it has
thin tube
-electronics in the hearing aid, just a tube in the ear
Receiver in the canal (RIC)
receiver, speaker in the tube

Location:
- Located behind the ear
- Has a hook that attaches to the earmold
Advantages:
Who? Can be fit to any motivated HI person
Has a lot of flexibility with features
Greater gain & MPO than smaller hearing aids
Telecoil is stronger than with smaller hearing aids
Only the earmolds need to be replaced as ears grow and change size/shape
--can use a loaner with their ear mold if it needs worked on
DAI is available (important for students)
Suitable for ears with medical problems
Possible Issues/Disadvantages:
More conspicuous than smaller aids
May fall off during work or recreation
May seem more difficult to insert, remove, and adjust volume control than a smaller hearing aid

7

In the ear (ITE)

fills up the entire apichure of the ear
custom fit to the person

8

kids generally have behind the ear. Why?

in the ear is a custom made aid, it would be hard to get that for a child because they are growing
a non fitting mold causes sound quality changing, whistling (feedback)

9

in the canal

provides a better look, but less flexibility to change the sound

10

mic and helix

the mic is in a tub that rests in the helix of the pinna so that the mic faces forward

11

feedback

when the mic is picking up the amplified sound the system is emitting
