most comfortable loudness MCL

the hearing level designated by a listener as the most comfortable listening level for speech

uncomfortable loudness level UCL

that intensity at which speech becomes uncomfortably loud

threshold of discomfort

TD another name for UCL

tolerance level

t.l. another name for UCL

loudness discomfort level

l.d.l. another name for UCL

range of comfortable loudness RCL

the difference, in decibels, between the threshold for speech and the point at which speech becomes uncomfortably loud. It is determined by subtracting the SRT from the UCL also called the dynamic range for speech

dynamic range DR

another name for RCL

speech-recognition score SRS

the percentage of correctly identified items on a speech-recognition test

word-recognition score WRS

the percentage of correctly identified items on a word-recognition test

phonetically balanced word lists

lists of monosyllabic words used for determining word-recognition scores. Theoretically, each list contains the same distribution of phonemes that occurs in connected English discourse

consonant-nucleus-consonant words CNC

monosyllabic words used in testing word recognition. Each word three phonemes; the initial and final phonemes are consonants, and the middle phoneme is a vowel or a diphthong

California Consonant Test

a closed-message word-recognition test, with the emphasis on unvoiced consonants to tax the abilities of patients with high-frequency hearing loss

Picture Identification Task PIT

a word-recognition test using pictures of rhyming CNC words

Word Intelligibility by Picture Identification test WIPI

a test that uses pictures to determine word-recognition ability in young children

Northwestern University Children's Perception of Speech test NUCHIPS

a picture-identification test for measuring the word-recognition abilities of small children

synthetic sentence identification SSI

a method for determining word-recognition scores by means of 10 seven-word sentences that are grammatically correct but meaningless

signal-to noise ratio SNR

the difference, in decibels, between a signal such as speech) and a noise presented to the same ear(s). When the speech has greater intensity than the noise a positive sign is used when the noise has greater intensity than the signal, a negative sign is used

Speech Perception in Noise test SPIN

a prerecorded sentence test with a voice babble recorded on the second channel of the same recording

Connected Speech Test CST

a procedure by which the intelligibility of speech passages is measured on a sentence-by-sentence basis in the presence of a related background babble

PB Max

the highest word-recognition score obtained with phonetically balanced (PB) word lists on a performance-intensity function, regardless of level

performance-intensity function for PB word lists PI-PB

a graph showing the percentage of correctly identified word-recognition materials as a function of intensity. The graph usually shows the word-recognition score on the ordinate and the sensation level on the abscissa

minimum response levels MRL

the lowest level of response offered by a child to an acoustic stimulus. Depending on a variety of circumstances, the signal responded to may be either barely audible or well above threshold

Apgar Test

a procedure for evaluating newborns in the hospital
Appearance, pulse, grimace, activity, respiration
low scores could indicate sensorineural hearing loss

auropalpebral reflex APR

a contraction of the muscles around the eyes

high-risk registry

list of indicators of hearing loss for identifying newborns who should be screened for hearing loss; outlined by the joint committee on infant hearing in 1994

early identification and treatment

The main purposes of infant hearing screening are _____________ and _____________.

hereditodegeneratie hearing loss

HL that has its onset after birth but is nonetheless herediatry

rapid and cost effective

Major advantages of using OAEs for infant hearing screening is the they are ____________ and __________.


If otoacoustic emissions are present, hearing loss is no greater than

behavioral observation audiometry BOA

observation of changes in the activity state of an infant in response to sound

localize sound

most BOA procedures rely on a child's ability to

Moro reflex

a sudden embracing movement of the arms and drawing up of the legs of infants and small children in response to sudden loud sounds

conditioned orientation reflex COR

a technique for testing young children in the sound field by having them look in the direction of a sound source in search of a flashing light

visual reinforcement audiometry VRA

the use of light or picture to reinforce a child's response to a sound


Transient-evoked otoacoustic emissions


Distortion-product otoacsoutic emisions


coating around a newborn


Behavioral observation audiometry

The Auditory Behavior Index ABI

an index of responsivity, not sensitivity
