FREE IHS Hearing Loss Assessment Question and Answers

Question 1

A tympanic membrane perforation may cause a:

Accepted Answer

Answer

Degradation effect.

Answer

Place theory.

Answer

All of above.

Question 2

User satisfaction must include:

Accepted Answer

patient preference.

Answer

parallel venting

Answer

Calcium deposits.

Answer

Loudest frequency

Question 3

What is a characteristic of a sensorineural loss?

Accepted Answer

-Loud talker
-Difficulty understanding high frequency consonants sounds
-Recruitment
-Tinnitus often preceeds it.

Answer

Greater for the low frequencies than for the higher frequencies.

Answer

high frequency average saturation sound pressure level with a 90 dB SPL input.

Answer

-A hearing level dial
-An attenuator dial

Question 4

A hearing aid that works with the battery door slightly open, but shuts off when you close the door:

Accepted Answer

wires touching the battery.

Answer

The second and third formants.

Answer

Differs at each frequency.

Answer

SAT- Speech awareness threshold

Question 5

Insertion Loss occurs when;

Accepted Answer

The level in the ear canal with a hearing aid inserted is less than the input level.

Answer

Bone conduction testing causing thresholds to shift due to headphones being placed over the ear.

Answer

presenting a tone that is only inaudible without the instruments on.

Answer

the instrument feeds back only when the coupler is removed.

Question 6

The sampling rate:

Accepted Answer

-refers to how often the waveform amplitude is measured.
-has a direct bearing on the frequency bandwidth of the hearing instrument.
-must be at least twice as fast as the highest desired frequency.

Answer

electronic microphone

Answer

Is easier to hear when a sound stops than when it begins.

Answer

-It is impossible to mask
-The patient displays a bilateral conductive loss
-Masking cannot be completed due to overmasking.

Question 7

Masking is performed during air conduction testing when:

Accepted Answer

-a 40 dB or more difference occurs between the air conduction threshold of th better ear and the poorer ear.
-a 40 dB or more difference occurs between the air conduction threshold of the poorer ear and the bone conduction threshold of the better ear.

Answer

After air conduction testing.

Answer

-have little or no effect on frequencies above 400 Hz.
-generally reduce levels at frequencies below 200 Hz.
-reduce atmospheric pressure build up.

Answer

are 20 dB less because of ANSI standards.

Question 8

High frequency Average SSPL 90 (HFA SSPL 90) refers to:

Accepted Answer

high frequency average saturation sound pressure level with a 90 dB SPL input.

Answer

saturation sound pressure level at 90 db spl.

Answer

average sound pressure level at 90 hz.

Answer

high frequency average saturation sound pressure level with a 180 db Spl input.

Question 9

Which surgical technique repairs the tympanic membrane?

Accepted Answer

Myringoplasty

Answer

Stapedectomy

Answer

Myringotomy

Answer

Cholesteaplasty

Question 10

Audiometric zero is:

Accepted Answer

0 dB Hearing Level
0 db HL
The level where normal ears can hear at every frequency.

Answer

increase in bone conduction sound for frequencies below 2000 Hz.

Answer

-Occurs in the middle ear
-May perforate the eardrum
-Is usually accompanied by a constant odorous discharge.

Answer

presenting a tone that is only inaudible without the instruments on.
