Abstract
A lipreading test was used to determined organic hearing levels of patients feigning deafness. The test material consisted of monosyllabic homophenous words. Other lists were presented at gradually reduced intensity levels until only visual stimuli was received. Homophenous words look alike but sound different, therefore, they cannot be perceived correctly by lipreading alone. Because of the nature of the test material, all correct responses depend upon audition. Being unaware of the true intent of the examination, the patient who is feigning deafness will continue to respond in this customary manner and thus reveal his organic hearing level.
