[Effect of several parameters of an acoustic signal on the shape of the iso-S contour].
Masking of amplitude irregularity in the two--component stimulus produced by step--like intensity increment (2, 3 and 6 dB) of the 800 Hz component, was studied. Variable frequency component of the stimulus served as a masker. The relationship between just masking level and the frequency of the masker (iso-S contour) was measured. The shape of iso-S contour appeared to be closely related to the value of the intensity increment of the 800 Hz component and only slightly dependent on the intensity level of this component.
