hearing handicap

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

at 1000 Hz, 0 dB HL is

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

if you look towards healthy side ...

nystagmus increases

if kid has no known ties to deaf culture and was learning to speak orally prior to going deaf, you want to use..

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

an 18 month old child should have a spoken vocab of

50 words

until the age of ___ months, babbling does not depend on auditory input

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.

when counseling parents of a child with hearing loss, the audiologist should..

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

the best acoustic signal for measuring frequency specific, absolute threshold in the sound field

FM tones

sounds below 1500 Hz rely on

ITDs

a pt who says they do better in noise than in quiet probably has..

CDHL

hearing better w a HL in noisy conditions versus quiet is a sign of

CDHL

most likely adult CI candidate

bilateral HL due to meningitis (bc they tend to be the most profound)

people with normal eustachian tube dysfunction have normal...

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

insertion loss

decrease in natural amplification when the auditory canal is closed off

hearing disability

determination of a financial award for the loss of function caused by any hearing impairment that results in significant hearing handicap.

reduced visual function that can complicated aural rehab is most common in patients with

diabetes

activity limitation

difficulty encountered when executing a task/action

participation restriction

difficulty experienced during involvement in life situations

post-active head shake test revealing left beating nystagmus indicates

dynamically uncompensated peripheral right vestibular lesion

strong motivation to wear HA is an indicator of

early positive acceptance of HA

to reduce the gain of low level sounds..

enable expansion

if they have good low frequencies through 1500..

go with a RITE open fit

intensity differences and spectral cues occur at

high frequencies

APGAR

higher score=excellent condition

HASP

include patients' self-perceptions in many areas related to core beliefs and attitudes that might impact the successful selection and fitting of amplification.

strongest correlation efficient

is the number farthest away from zero

fixed setting of the hearing-level dial of a pure-tone audiometer, what is true of the actual sound-pressure level (SPL) output of the audiometer earphone?

it is lowest at mid frequencies highest at low frequencies, increases at high frequencies

CPHI

lengthy Communication Performance, Communication Environment, Communication Strategies, and Personal Adjustment.

PHAP

lengthy assess experience with amplification in terms of speech communication in three types of listening situations and in terms of reactions to amplified environmental sounds.

HHIA

lengthy may have questions that don't refer to the pts lifestyle specifically emotional/social/situational

Test-retest reliability and split-half reliability are

measures of how consistently a test ranks a group's performance on a test

common medical conditions associated with ped balance disorders

migraine, BPVC, OM, viral infection, head trauma

continuous interleaved sampling

minimizes the channel interaction by presenting pulses to each electrode in a non overlapping sequence

if you don't account for RECD when fitting an infant, you will most likely..

overamplify them The output SPL in an infant's ear is typically higher than it is in a coupler because of the small ear canal volume in an infant's ear.

hardest for those with hearing loss to distinguish

placing

COSI

promotes focus on patient's individual needs when designing a rehab program IN A TIMELY MANNER

what type of signal is used for identification audiometry for school aged children, according to ASHA

pure tone signals

otologically normal 13 y.o boy is lying to you on audio testing. you should..

reinstruct and use ascending method

a false positive when doing audiometric testing indicates

response occurs in absence of stimulus

the ability of a test to measure what it was designed to measure

the process of eliminating or reducing harmful microorganisms from inanimate objects and surfaces ok for "non critical" items that do not touch blood/potentially infectious areas/not likely to break the skin

sterilization

the process of killing all microorganisms needed if object is contaminated with blood, mucous, or other bodily fluids *cold sterilization w chemicals

performance level rises most steeply with small increases in intensity when...

the speech sample is large and provides some context

analog hearing aids do not allow for...

the storage of different frequency responses so the client can adapt the aid to different listening situations

single subject design

when professional has inappropriate training for said procedure
