Fig. 1. (A) Stimulus waveform (the example is a 4-kHz signal). (B) Frequency spectra of the stimulus. Solid line, electrical signal; broken line, reproduction with frequency–response irregularity of the speaker 16 dB/octave; frequency is presented in multiples of the carrier frequency f. Straight lines in B show the spectrum width at a level of 0.5 (–3 dB) re maximum.
