Flashcards in Speech Audiometry Deck (18):
1

Speech Audiometry

Requires the Audiometer
Must be 2 channel audiometer; allows for different tones/words to be played in each ear

The Speech May be Recorded:
CD, MP3, internal (preprogrammed in the audiometer), etc

MLV = monitored live voice (own voice)
Problems with MLV = voice quality, dialect; must keep consistent volume, must be monotone; not as accurate

VU Meter
Monaural
Binaural – goal, one ear with speech, other with static

VU meter measures loudness; should be at 0 on the meter; loudness + side, quieter - side

2

SDT

Speech-Detection Threshold

Used for:
Kiddos (6mos to 2ish)
No word understanding – foreign language speaker
Profound SNHL
Developmentally Delayed

Indicated when speech sounds are heard: “ba-ba-ba-ba” – words don’t matter, just some speech sound

3

SRT

Speech-Recognition Threshold

Lowest hearing threshold at which speech can barely be understood and repeated 50%

Spondaic words (spondees)
Hotdog, cowboy, baseball, ice cream, sidewalk, toothbrush

4

Spondees

words with no inflection up and down or change in volume, pitch

5

ASHA Method SRT Testing

Familiarize client with words

Use the “down10, up5” method

Start @ 60 dBHL: present 5 words, one at a time

Drop 10 dBHL in intensity until the patient cannot respond correctly

Increase 5 dBHL until the patient responds correctly

6

Alternate SRT Testing

Do not familiarize with words

Start at 30 dBHL

If patient doesn’t respond, go to 50 dBHL

Increase by 10 dBHL as the patient needs more volume

Then use the down10, up5 method as needed

7

Speech/Pure Tone Relationship

The SRT should closely match the pure tone testing results on the audiogram

Closest to 1000Hz or btwn of 500Hz and 1000Hz

8

MCL

Most comfortable loudness

Patient indicates which level of speech is most comfortable

Speech is slowly increased until the patient says it’s too loud, then the volume is dropped


9

UCL

Uncomfortable loudness level *(UCL)

Some uncomfortable from loudness, others from the pressure

AKA:
Threshold of discomfort (TD)
Tolerance level
*Loudness discomfort level (LDL)

10

DR

Range of comfortable loudness or *Dynamic Range (DR)

Intensity range between threshold and UCL; how loud the patient can stand the sound

11

WRS

Speech-recognition scores (SRS) or Word-recognition score *(WRS)

Most commonly used as WRS
Live voice vs recorded speech

Measures how well a person should understand speech

Extent of speech understanding difficulty

Aids in proper amplification
Aids in diagnosis of site of lesion

12

PB

Phonetically balanced words (PB)

No emphasis on any part of the word

CID W-22; 50 words- 25 words per ear (word lists)

Consonant-Nucleus-Consonant Word List (CNC)
Consonant, vowel or dipthong, consonant

13

WRS Testing Methods

Speech!

Above the age of 4, they should be able to repeat what you say

Above the age of 3, use picture pointing
Big board with pictures of: hotdog, sailboat, baseball, toothbrush etc

Above the age of 2, attempt picture pointing

Below the age of 2, use the speakers (soundfield testing)!


14

Soundfield testing

Client sits in the middle of the speakers

Patient looks toward the speaker producing the sound

15

VRA

Soundfield Testing

Visual Reinforcement Audiometry (toy lighting up)

Can use speech or pure tones?

Downfall? Tests the better hearing ear

16

CPA

Soundfield Testing

Conditioned Play Audiometry

AuD goes in the booth; models desired response when beep is heard; child should imitate response when tested

Blocks, high fives, counting, etc!

Ex: throw ball in bucket when you hear the beep

17

How loud to do WRS?

SRT + 40 dBHL
OR patient’s MCL!
ex: SRT is 75 dBHL, you don’t want to blast them with 115 dBHL

Almost ALWAYS mask for speech
How much? WRS of testing ear ALWAYS – 20 dBHL
**Remember- masking always goes in OPPOSITE EAR!

18

Speech Banana

Most vowels in the lower frequencies; give speech volume

*High frequencies give clarity of speech
