FIELD: technology for estimating and indicating distortions of output signal of audio frequency amplifier, appearing as a result of its top limit in sound frequency amplifier (amplifier overload).
SUBSTANCE: statistic coefficient of output signal is measured, such as dispersion, average-quadratic value, average-rectified value, average number of exhausts. Produced estimate is compared to preset threshold value. Threshold value is determined on basis of subjective-statistical expertise, showing noticeability grade of distortions. On basis of comparison results, decision about indication of distortions is taken.
EFFECT: increased efficiency of indication of audio signal distortions due to consideration of psychic-physiological particularities of humans.
