audiometry(od?e-om'e-tre) [ audi- + -metry]
A test that measures the ability to detect sounds of varying frequencies and varying levels of loudness. audiometric (-e-o-me'trik), adjective; audiometrist (-om'e-trist) See: spondee threshold
averaged electroencephalic audiometry
A method of testing the hearing of children who cannot be adequately tested by conventional means. The test is based on the electroencephalogram's being altered by perceived sound without the need for a behavioral response; therefore, the test may be done on an autistic, severely retarded, or hyperkinetic child who is asleep or sedated.See: auditory evoked response
behavioral observational audiometryAbbreviation: BOA
A hearing test for individuals (such as children aged 6–8 months) who may not be able to signal their responses to sounds with speech or gestures, but who may reorient their eyes or bodies in response to sounds. Interpretation of BOA results is subjective and may not be reproducible.
brainstem evoked response audiometryEvoked response audiometry.
evoked response audiometry
A computer-aided technique to average the brain's response to latency of auditory stimuli. Auditory brainstem evoked response (ABER), one kind of this type of audiometry, is used to test the hearing of those, esp. children, who cannot be tested in the usual manner.Synonym: brainstem evoked response audiometry
Audiometry that combines acoustic reflex testing, a reflex decay test, and tympanometry. Formerly called impedance or tympanometry testing, it is a test that measures the structural integrity and normal functioning of the tympanic membrane and the middle ear.
A hearing test of preschool children (ages 3 and up) in which the child is asked to drop a toy into a pail whenever he or she hears a tone.
pure tone audiometry
A test to determine hearing sensitivity and hearing loss in response to different sound frequencies. The test subject is exposed to sounds of specific frequencies within the normal range of human speech (about 250– 8000 Hz). Each tonal frequency is presented to the subject at different increasing intensities or decibels of sound until he or she identifies the frequency. A chart is constructed representing the range of detectable frequencies and the sound intensity (loudness) required to elicit a response from the subject.
A test of the ability to hear and understand speech. The threshold of detection is measured in decibels.
visual reinforcement audiometry
A method of testing the hearing of children under 3 in which the child is rewarded when he or she looks toward a sound source.
