Audio—visual speech perception a preliminary report

Abstract

By means of a video—recorder connected to a speech audiometer and a television set it is possible to vary independently the two parameters, the picture and the sound level. The communication score of 100 persons was found in relation either to the visual perception alone or to the auditive perception and, finally, to a combination of both. In the group of patients with medium lipreading ability there seems to be a fairly good correlation between this ability and the reduction of their hearing loss measured in decibels. A small group seems to have a special capacity of combining vision and hearing.
