In a psychacoustic experiment , intervals between tonal stimuli and responses at different sound levels allow one to differentiate real threshold functions from limited responding. The audiometric and time measuring procedure has to be applied in a designated manner. A range of about 20 dB and steps of sometimes as small as 1 dB must be employed. Disturbed behavior during audiometry (resulting into pseudohypacusis) is then indicated by prolonged latencies, unsteady correlation of time intervals and stimulus level or fluctuating threshold of reaction. Limits of reaction intervals were established.
