Auditory Evoked Potential Testing
Comprehensive hearing testing. This involves using varying levels of sound across many different frequencies to determine current hearing sensitivity. Testing may include different types of headphones, tones, speech, and noise components.
Tympanometry. Use of various tones and changes in air pressure allow for measurements to be made regarding the integrity and function of the tympanic membrane (Eardrum), middle ear, Eustachian tube, and certain nerve functions.
Auditory evoked potentials. For this testing, electrodes placed on the skin measure electrical changes from the hearing nerves as sounds are played in the ear.
