Speech Testing

Question 1

What is quicksin

Answer 1

-It is a speech noise test.
-2-3 mins long
-Sets realistic expectations
6 sentences with 5 key words
-Pre recorded SNR which decreases in 5dB steps each sentence
-it finds the relationship between the volume of speech presented and the understanding of that speech

Question 2

What can speech audiometry be used to do

Answer 2

• it detects the presence of speech
  -distinguishes one word from another
  -recognises words
  -understand the meaning of words/sentences

Question 3

What is SRT

Answer 3

Speech recognition threshold test
-uses spondee words (equal stress of both syllables)
-word is present and patients repeats
-if correct, decreaSe by 10dB and present diff word
-continue until no response
-continue until 3 out of 6 words are correct
- recorded results for each ear and they should be within 10dB of PTA average

Question 4

What is SDT

Answer 4

Speech discrimination test
-phonetically balanced word list
- monosyllabic words of common use
-helps with recommending aid if patient can only have one
- fit ear that needs most help

Question 5

What is the Arthur boothroyd test

Answer 5

• it is a consonant - vowel - consonant test
• for adults and older children
  -10 words
  -each word can be scored out of 3
  -1 for each sound
  -max score of 30

Question 6

What is ANL

Answer 6

• it is acceptable noise level
• assists in predicting success of fitting aids
• free field - recorded voice
  -2 min test time
• 2 channel audiometer

Question 7

What is the process of ANL

Answer 7

• patient listens to story, volume adjusted to find MCL
• introduce noise, increase and decrease until they report max level they could listen and understand speech still BCL = background noise level
• so ANL = MCL-BCL
  the closer the mcl and bcl are the better the probability of success in aids will be

Question 8

What is the audibility index audio gram

Answer 8

Count the dots below the threshold.
There are 100 dots and the more dots counted = the better they will hear speech

Question 9

What is speech shaped noise?

Answer 9

This is used in speech testing instead of masking because of the following:
The intensity is weighted across all frequencies to mimic speech sound. There are dips in it so there are parts where the noise stops and patients can pick up on what’s being said which is more realistic than masking noise which was the same intensity across all frequencies.
