[Latencies of reaction indicating disturbed behaviour during evaluation of pure tone threshold (author's transl)].
In a psychoacoustic experiment intervals between tonal stimuli and responses at different sound levels allow 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 behaviour during audiometry (resulting into pseudohypacusis) is then indicated by prolonged latencies, unsteady correlation ot time intervals and stimulus level, or fluctuating threshold of reaction. Limits of reaction intervals have been established.
