Question | Answer |
---|---|
audiometry | process of measuring hearing |
audiometer | instrument to measure hearing |
audiogram | record of hearing measurement |
audiologist | health professional who specializes in the study of hearing impairments |
auditory acuity testing | physical assessment of hearing; useful in differentiating between conductive and sensorineural hearing loss |
tuning fork | a two-pronged, fork-like instrument that vibrates when struck; used to test hearing, especially bone conduction |
brainstem auditory evoked potential (BAEP) | electrodiagnostic testing that uses computerized equipment to measure involuntary responses to sound within the auditory nervous system; commonly used to assess hearing in newborns |
otoscopy (see Fig. 11-2) | use of an otoscope to examine the external auditory canal and tympanic membrane |
pneumatic otoscopy (see Fig. 11-3, A) | otoscopic observation of the tympanic membrane as air is released into the external auditory meatus; immobility indicates the presence of middle ear effusion (fluid buildup), as occurs as a result of otitis media |
tympanometry | measurement of the compliance and mobility (conductibility) of the tympanic membrane and ossicles of the middle ear by monitoring the response to external airflow pressures |
