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 __________.
mild
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
TEOAEs
Transient-evoked otoacoustic emissions
DPOAEs
Distortion-product otoacsoutic emisions
vernix
coating around a newborn
BOA
Behavioral observation audiometry
The Auditory Behavior Index ABI
an index of responsivity, not sensitivity
