| audiometry, speech | Measurement of the ability to hear speech under various conditions of intensity and noise interference using sound-field as well as earphones and bone oscillators. (12 Dec 1998) |
|---|---|
| auditory brainstem response audiometry | An electrophysiologic measure of auditory function utilizing responses produced by the auditory nerve and the brainstem to repetitive acoustic stimuli. (05 Mar 2000) |
| automatic audiometry | An audiometric technique using an automatic audiometer, which enables the patient to track his own hearing thresholds by controlling the intensity of the signal being presented to him, while the audiometer sweeps through the audible frequency range. (05 Mar 2000) |
| Bekesy audiometry | Automatic audiometry utilizing the Bekesy audiometer; the patient makes two threshold tracings, one in which the tone is rapidly turned on and off (interrupted tone) and one in which the tone is presented steadily (continuous tone); results may be suggestive of middle-ear, cochlear, or eighth nerve lesions. (05 Mar 2000) |
| brainstem evoked response audiometry | An electrophysiologic measure of auditory function utilizing responses produced by the auditory nerve and the brainstem to repetitive acoustic stimuli. (05 Mar 2000) |
| cortical audiometry | Measurement of the potentials that arise in the auditory system above the level of the brainstem. (05 Mar 2000) |
| screening audiometry | Rapid measurement of the hearing of an individual or a group against a predetermined limit of normalcy; auditory responses to different frequencies presented at a constant intensity level are tested. (05 Mar 2000) |
| pure-tone audiometry | Audiometry utilizing tones of various frequencies and intensities as auditory stimuli to measure hearing, including comparisons of results from testing air conduction and bone conduction. (05 Mar 2000) |
| speech audiometry | Measurement of overall performance in hearing, understanding, and responding to speech for a general assessment of hearing and an estimate of degree of practical handicap. (05 Mar 2000) |
| diagnostic audiometry | Measurement of hearing threshold levels to determine the nature and degree of hearing loss (e.g., conductive, sensorineural, or mixed). (05 Mar 2000) |
| electrodermal audiometry | A form of electrophysiologic audiometry used to determine hearing thresholds by measuring changes in skin resistance as a conditioned response to noise stimuli. (05 Mar 2000) |
| electrophysiologic audiometry | Measurement of a patient's response to a sound stimulus by using various types of objective audiometric equipment or techniques without necessarily having the patient's conscious cooperation. (05 Mar 2000) |
| evoked response audiometry | A type of electrophysiologic audiometry in which electrical potentials of neural impulses from the cochlear nerve and various levels in the brain in response to acoustic stimulation are used to localise the site of a lesion causing a hearing loss. (05 Mar 2000) |
