What is the most common response mode during clinical speech audiometry |
The common response mode is verbal that is the patient vocally repeats the speech test item such as a word or a sentence |
|
What does sdt stand for |
Speech detection threshold also referred to as speech awareness threshold or sat |
|
What is sdt |
sdt is the lowest intensity level in decibels hearing level DB HL at which a person is aware of or can detect the presence of a speech signal measurement sdt does not require the patient to repeat or understand speech only awareness is needed |
|
How is sdt or sat measured in infants and young children |
The audiologist observes the child's head turning or localization response to the presentation |
|
True or false speech recognition measurement is preferred over SDT with the patient repeating words rather than simply responding to the presence of speech |
True |
|
What is a spondee |
A word that consists of two syllables with equal stress on each syllable |
|
What does SRT stand for |
Speech recognition threshold or speech reception threshold |
|
At what db are SRT tests generally begun if normal hearing is suspected |
It starts at a comfortable intensity level of 30-40 dB HL |
|
What are the typical measured intensity levels for sdt when compared to SRT |
Typically there measured at intensity levels from 6 to 10 decibels lower or better than the intensity levels for SRT |
|
What is articulation index |
It describes the percentage of speech that is Audible |
|
What is MCL |
Most comfortable level |
|
when a patient has a very poor wrs or word recognition score that is inconsistent with the hearing loss present it may be a sign of a possible what |
Retro cochlear disorder |
|
What decibel above the patient speech recognition threshold is the standard for beginning a word recognition testing |
40 |
|
What is the rollover effect |
It refers to a diminishing word recognition score the point where the score begins to decrease |
|
Do we need to mask if there is a no response and no threshold was reached |
If there's no response without masking then there's no need to mask |
|
What is the occlusion effect |
the enhancement of bone-conducted sound signal caused by blocked or occluded ear canals. |
|
At what hertz does the occlusion effect the apply |
applies to 250, 500 and 1000 Hz frequencies |
|
When should you test interoctave frequencies |
When the difference between octaves is 20 DB or more you test the interoctave frequencies |
|
At what DB should you present a spondee to find the SRT |
30 or 40 db |
|
What should you do if the response is incorrect at 30 DB |
The stimulus should be increased to 50 DB |
|
What is the bracketing technique |
the bracketing technique requires presenting one word at each level by increasing the stimulus in 5 dB for incorrect response and decreasing in 10 db for correct |
|
How many responses need to be correct at any given level for the bracketing technique |
Three correct responses |
|
True or false we test word recognition before determining SRT |
False after determining SRT we can test for word recognition |
|
What is the standard method DB to set the presentation level above SRT |
30 to 40 DB above the SRT |
|
Does LDL stand for |
Loudness discomfort level |
|
What does MCL stand for |
The most comfortable level |
|
At what decibel hearing level above audiogram thresholds is the most reported by people for MCL for Pure tones or speech |
Most normal hearing persons will report mcls for Pure tone or speech that are 40 to 50 DB higher than audiogram thresholds |
|
True or false the MCL gives important information for the fitting of a hearing instrument |
True |
|
How do you find the MCL |
We use cold running speech and the bracketing method |
|
True or false we are going to increase by 5 decibels or 10 decibels and then say a word to determine the MCL |
False we continue with cold running speech and quickly increase in five decibels |
|
True or false we increase the level of intensity slightly above what the patient reports speech as comfortable when determining the MCL |
True |
|
How do we find the LDL or the loudness discomfort level |
With cold running speech |
|
What is RCL |
Range of comfortable loudness |
|
How do we determine the RCL |
You subtract the SRT from the LDL |
|
How many syllables use in the word recognition test |
One syllable words |
|
How many syllables are used in the speech recognition |
Two syllable spondee |
|
True or false it is not recommended that the audiologist performs the test at two different levels for word recognition |
False it's recommended to verify the patient's maximum performance |
|
How are the results of the word recognition test Expressed |
Word recognition score is in percentage the percentage of test words correctly repeated by the patient |
|
What is retrocochlear disorder |
an abnormality in the auditory system that involves the 8th cranial nerve or other structures toward the central nervous system form of the inner ear like an acoustic tumor |
|
What would you assume is the LDL for patients with sensorineural hearing loss |
About 90 decibels |
|
What would you say is the LDL for a person with normal hearing |
100 to 110 DB |
|
How many words are on the list for word recognition test |
