electrodermal audiometry

Etymology: Gk, elektron + derma, skin; L, audire, to hear; Gk, metron, measure
a method for determining hearing thresholds in which a harmless electric shock is used to condition the subject to a pure tone, which thereafter, coupled with the anticipation of a shock, elicits a brief electrodermal response. The lowest intensity of the sound that produces the skin response is considered the subject's hearing threshold. It is a very old procedure and rarely used today.

electrodermal audiometry

An obsolete method for measuring hearing by quantifying the difference in electrical resistance of the skin following auditory stimuli.

elec·tro·der·mal au·di·om·e·try

(ĕ-lek'trō-dĕr'măl aw'dē-om'ĕ-trē)
A form of electrophysiologic audiometry used to determine hearing thresholds by measuring changes in skin resistance as a conditioned response to noise stimuli.
