This paper is concerned with measurements of amplitude modulated (AM) thresholds of a tone, modulated by means of a signal consisting of three sinusoids of equal amplitudes and low frequencies. By changing starting phases of each sinusoid it was possible to get modulators characterized by different crest factors, keeping constant their root-mean-square (RMS) values. This experiment demonstrated that when amplitude of a tone changed very slowly, AM thresholds did not depend on a crest factor of a modulator even when subject followed instantaneous changes in amplitude of the tone. Therefore, it can be assumed that listener's decision is made based on the RMS value of amplitude changes in a signal.
