Exam 1 Part 5 Flashcards
What type of hearing loss is associated with a sloping configuration?
Sensorineural
What type of hearing loss is associated with a rising configuration?
Conductive
What type of hearing loss is associated with a notched configuration?
Noise induced (sensorineural)
What type of hearing loss is associated with a fragmentary configuration?
Deafness
What type of hearing loss is associated with a cookie bite configuration?
Congenital, developmental cause
True or false: Bone conduction can be worse than air conduction
False; can’t be worse
True or false: Bone conduction can be better than air conduction
True
True or false: Bone conduction tests test both of the ears or the better cochlea
True
What is the only way we know that we are testing a certain cochlea?
If we mask it
Conductive hearing loss is no more than ___ dB
60
Softests level that a given listener can hear a sound
Threshold
What is the operational definition of threshold?
Level of sound that can be heard by an individual 50% of the time
What is the clinical definition of threshold?
Lowest level at which 3 responses are first obtained
What is the technique we use for pure tone audiometry?
Modified Hughson-Westlake technique
What are the 3 phases of the Modified Hughson-Westlake technique?
Familiarization, descending, threshold
Familiarize patient with stimulus and asking them to raise their hand when they hear the tone
Familiarization
What intensity do you start with during familiarization?
40 dB
Decreasing level of stimulus
Descending phase
How much do we descend during the descending phase?
10 dB
Phase during pure tone audiometry when we find the threshold
Threshold
During the threshold phase we go ___ up ____ down and we always ____ to threshold
10 up, 5 down, ascend
Response must be right after stimulus is presented
Latency consistent
Don’t fall into rhythm of presenting the stimulus
Avoid pattern of presentation
What is the order we use to test pure tone audiometry in dB HL (6)?
1000, 2000, 4000, 8000, 1000, 500, 250
Person raises hand when we didn’t present a stimulus
False positives
What happens if there are no false positives present?
Person is too conservative and should be encouraged to raise hand more
