Q

Word Recognition Testing Definition

A

Assesses pt’s ability to correctly identify spoken words presented above threshold

17
Q

Word recognition Testing Stimuli

A

Monosyllabic Words

18
Q

Word Recognition Testing Presentation Level

A

40 dB sensation level (dB SL) (add 40 to SRT)

19
Q

WRT Score categories

A

90-100% = excellent,
80-89% = good,
70-79%=Fair,
60-69%=poor,
<60% = very poor

20
Q

Expected performance-intensity function for normal vs. conductive vs. sensory vs. neural/retrocochlear loss

A

-normal=100% correct around 40 dB above SRT. -Conductive= reaches 100% correct around 40 dB above SRT, but at a higher intensity than normal hearing.
-Sensory (cochlear)= does not reach 100% even at high intensity levels.
-Neural (retrocochlear)= as intensity increases, performance reaches a point where it starts to decrease.

21
Q

Signal-to-noise ratio: How to compute if given a signal and noise level

A

Speech – Noise= S-to-N ratio in dB

22
Q

Cross-Hearing Definition

A

Sound presented to one ear can reach the opposite cochlea via bone conduction

23
Q

interaural attenuation

A

The decibel reduction in sound intensity that reaches the opposite cochlea

24
Q

Values of interaural attenuation

A

-Insert earphones = 50 dB, -supra-aural headphones = 40 dB,
-bone oscillator = 0 dB

25
Q

For a given intensity level and a given transducer, determine the intensity level that reaches the opposite cochlea

A

intensity level of tone minus interaural attenuation = tone reaching opposite cochlea

26
Q

What happens if we fail to mask for air conduction and for bone conduction

A

We will underestimate the threshold.

27
Q

symbols for masked air conduction and masked bone conduction thresholds

A

Right masked air conduction= triangle (tone in right ear, masking noise in left),

left masked air conduction = Square (tone in left ear, masking noise in right ear),

Right masked bone conduction = square bracket eating the bar to the right (oscillator on right mastoid, masking tone via air conduction in left),

Left masked bone conduction = square bracket eating the bar to the left (bone oscillator on left mastoid, masking tone in right ear)

28
Q

determine the degree of hearing loss based on masked thresholds

A

use masked thresholds for degree if present!

29
Q

determine if masking is needed for air-conduction and for bone conduction

A

air=if difference between air conduction threshold in test ear and bone conduction threshold in opposite ear is greater than or equal to interaural attenuation.

Bone=when ac threshold and unmasked bc threshold in same ear is greater than or equal to 15 dB
