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 audiometryAn 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.
