Pop quiz questions/questions from notes Flashcards
What is the stenger principle?
Tone presented in both ears, patient only hears it in one - this means there is a greater hearing loss in one ear than the other (or no hearing loss in the other)
What is the occlusion effect?
Perception of bone conduction increases when ear canal is plugged (because it reverberates off the closure)
What are two reasons to use a loudspeaker?
Kids
To test the outcome of hearing aids
Why do we use a pure tone?
It stimulates a discrete region of the basilar membrane
Why do we use clicks and transients?
To assess auditory function
Pure tone audiometry uses what type of perceptual response?
Detection
When do we use physiological/passive responses?
Young kids
Old people with dementia or Alzheimer’s
People trying to fake a hearing loss
A physiological response does not _ it assess _
Does not give us hearing thresholds
Assess the auditory system
What information does tympanometry give you specifically?
Everything you want to know about the middle ear function
What does Otoacoustic emissions tell us?
Tells us about the health of our outer hair cells
What does cross check in the diagnostic process mean?
Checking test results against different types of tests
When do we test for 750 and 1500Hz?
Difference of 20dB or greater between 500 and 1,000 and/or 1,000 and 2,000
Comparing air conduction to bone conduction is a way to determine:
TYPE of hearing loss
What is a significant air-bone gap?
15dB or greater
Right ear air conduction hearing is marked on an audiogram with:
