Forty-five normal-hearing subjects were divided into three groups according to sophistication regarding Bekesy audiometry in simulated hearing loss. Both standard pulsed (200 msec on/200 msec off) and lengthened off-time (200 msec on/800 msec off) were compared with a continuous tone tracing at 1000 Hz. Data revealed a general decrease in the number of Type V patterns observed as sophistication increased.
