hearing handicap

the disadvantage imposed by a hearing impairment on a person's communicative performance in the activities of daily living

7 dB SPL (add to dB HL in question to get total dB SPL at that frequency)

oral/aural communication

the annular ligament is closest to the

oval window

at 8000 Hz, 0 dB HL is

13 dB SPL

interaural differences in calorics must be

20% or greater to be significant

50 words

6

consider gestational age over chronological age when interpreting

ABR Wave 5 latencies

ABR for retrocochlear loss

Absent waveforms, IPL increased by > .25 ms, IA wave V latency difference of > .2 ms, amplitude ratio V/I is < 1

best kind of fitting for emphasizing HFs in HA

Acoustic modification should emphasize high-frequency amplification and de-emphasize low-frequency amplification. A short sound bore, a flared horn (Libby), and a wide vent is the best combination to achieve that goal.

Assume that much information will need to be repeated at a later date, since parents generally will recall very little of the material presented initially

ECV

ABR for CDHL

EXTREMELY delayed absolute latencies, with IPL within normal limits

ototoxicity can cause

HF HL with bilateral vestibular loss, such as ataxia of gait/stance

larger/smaller number is better for AIDI

LARGER

WDRC

Low compression threshold, low compression ratio -WDRC provides gain adjustment across a wide range of input levels. It provides additional gain for low input levels with a low compression threshold and provides gradual increases in gain as input levels increase using a low compression ratio.

guidelines for acceptable noise can be found at...

OSHA

way to test rollover

Open-set, monosyllabic, phonetically balanced word lists, administered at several intensity levels -Speech understanding may be affected in a patient with a suspected retrocochlear lesion. Administering a performance-intensity function and then calculating rollover would be an appropriate step before referring the patient for more objective tests to rule out a retrocochlear lesion.

the acoustic reflex is mediated at the

SOC

used to measure noise in classrooms

Sound level meter

ABR for SNHL

Wave I is delayed. Wave V latency is delayed at "normal" presentation levels, but as intensity of stimuli increases (to overcome the SNHL), the latency of Wave 5 will be prolonged. *this leads to Wave I-V having a NORMAL IPL, despite the fact that Wave I is delayed.

what would NOT enhance the high frequency response of a HA, as measured in the ear canal?

a bore with a narrow diameter

hearing impairment

a deviation or change for the worse in either auditory structure or auditory function, usually outside the range of normal

false positive in audiometry

a response occurs in the absence of a stimulus, such as when a patient responds even though no signal has been presented.

a language stimulation program for a 6 month old should

be integrated with routine activities in the home

use of inserts over headphones for ABR testing generally changes...

absolute latencies (delay of sound traveling through the tubes)

functional gain of HA is best determined by

aided vs unaided sound field thresholds

between group design

an experiment that has two or more groups of subjects each being tested by a different testing factor simultaneously.

the _____ ligament holds the stapes to the oval window

annular
