Familiarization
1000 Hz continuously on completely attenuated and gradually increase until response occurs
Don’t mark till after first no response
Threshold is
not absolute and is more of a range that can be influenced
What is the duration that a tone should be presented?
1-2 seconds
Ascending Method
Start well below expected threshold
Determined by preceding response
Failure to respond
then increase 5 dB until response
With response decrease 10 dB
Descending Method
Start above expected threshold
Failure to respond
then increase 5 dB until response
With response decrease 10 dB
The interoctaves
750 and 1500 Hz
Diagnostic Techniques
Purpose: To find out exactly what kind of hearing loss someone has.
How It Works: Tests a wide range of sounds and volumes to make a detailed hearing map (audiogram).
When It’s Used: When someone notices hearing problems or needs a full hearing evaluation.
Monitoring Technique
Purpose: To check for changes in hearing over time.
How It Works: Tests just a few key frequencies quickly to see if hearing is getting worse.
When It’s Used: For routine check-ups, like in noisy workplaces or if someone is taking medicine that might affect hearing.
If the Diagnostic Technique is being used and a low-frequency hearing loss exists then 125 Hz should be tested.
True
The Diagnostic Techniques test 250 Hz and the interoctaves, 750 Hz and 1500 Hz, where the Monitoring Technique doesn’t.
True
When testing what ear should you test first?
Test the better ear first and if they don’t have a better ear then test the right one first
The initial test frequency is
1000 Hz
Once you go through all the frequencies in the first ear, you should retest 1000 Hz
True
Is it necessary to retest 1000 Hz in the second ear?
No
Interoctaves only need to be tested in the ear that needs it.
True
