I don't know Flashcards
Tactile responses
When patient feels stimulus instead of hearing it (low frequencies, high intensities, bone conductor)
pseudohypacusis
Diverse collection of patients with false or exaggerated hearing loss
Nonorganic hearing loss
This phrase implies that there is no anatomical or physiological abnormality in the auditory system
Functional hearing loss
Suggests abnormal hearing tests with no apparent physiological or anatomical basis
Malingering
Malingerer is assumed to be intentionally and deliberately producing flase hearing test results, often for personal monetary gain
Stenger test
Used on patients with unilateral hearing loss. Good for catching malingerers.
Speech materials
Various speech stimuli used in speech audiometry
What controls the intensity level of the speech signal?
Hearing level dial
What controls the intesity of the speech materials for each channel?
Monitor Ch1 and Monitor Ch2
Calibration knob
Used to make small adjustments in the intensity of the speech signals during the calibration process to assure accuracy of the speech signal to the patient
What is the intensity level that a patient perceives as comfortable to listen to?
Most comfortable level
What is the intensity level at which sound becomes uncomfortable or causes discomfort?
Loudness discomfort level
Carrier phrase
A short phrase, usually three words, that comes before the presentation of each word
Open-set response test
Patient has no advance notice about which word they are about to hear
Closed-set response test
The patient responds to a test word within a limited collection of possible words
signal-to-noise ratio
The relation between the intensity level of the words and the intensity level of the background sound
multi-talker babble
A recording of actual environmental noise with many people talking in the background where it is impossible to follow any of the conversations
The cocktail party effect
Background noise is present in a small group of speakers but with some effort a normal-hearing listener can understand what each speaker is saying
articulation index
used to describe the amount of speech that is audible
initial masking
the minimum level of masking noise necessary to produce a 5 dB shift or increase in air conduction thresholds in the non-test ear
effective masking
the amount of noise that definitely makes a specific signal such as a pure tone inaudible to the non-test ear
minimum masking
the lowest noise level that just masks a pure tone or speech signal of a certain intensity level
Maximum masking
The highest level of masking noise that should be presented to the non-test ear
Under-masking
The intensity level of masking noise is too low and the non-test ear may still contribute to the patient’s response
