Masking Period Patterns of Amplitude Modulated Pure Tones
Masking-period patterns of 1000 Hz-maskers revealing either 100% sinusoidal or square wave amplitude-modulation are measured. Modulation frequencies of 4 Hz, 10 Hz, 30 Hz and 100 Hz and test-tone frequencies of 800 Hz, 1000 Hz (in phase), 1600 Hz and 3200 Hz are applied. The masker level is the parameter. Results can be explained taking into account the non-linear behaviour of masking effects, the temporal effects in post stimulus-masking and temporal summation at threshold over a period of 200 ms.
