The CON-SOT-LOT Test for Nonorganic Hearing Loss

The efficacy of a screening procedure for detecting nonorganic hearing loss using standard audiometric instrumentation was examined . Thirty normal-hearing subjects' responses to continuous and standard and lengthened off-time pulsed tones, using an ascending-descending method, were compared . Subjects were asked to respond to test stimuli in normal-hearing and simulated hearing loss conditions. Data show that there are clinical and statistical differences between subjects' response patterns in the normal-hearing condition as compared to the feigned hearing loss condition. The procedure is offered as a simple method of screening for nonorganic hearing loss.
