SOUND-SOUND INTERACTION
Answer |
Backward masking.
When the gap is 100 ms (case A), you can probably hear
all steps of the ramp clearly. When it narrows to 20 ms
(case B), the last 2 or 3 steps show signs of being
masked. With a 0 gap (case C) it is virtually impossible
to hear the tones in the ramp at all. About 10 ms
between tone and noise would be necessary to hear the
tone separately. |
