Steady-state masking noise varies perceptually even with a 100-ms time shift.
Evidence
Most remarkably, even a 100-ms time shift in the white masking-noise waveform induced significant perceptual variability, indicating that “steady-state” masking noise should not be considered steady over time in the context of consonant cues. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5575
Categorization
- QUESTION: Worth chasing: what acoustic property of a 100 ms time-shifted frozen noise changes consonant cue masking? Purely a fine-timescale envelope effect?
- corroborated: 2 independent passages support this claim — Dijk, Pim van, Physiology, Psychoacoustics and…, 5575
- XREF: connects to: Time-shifting an identical noise masker changes consonant perception measurably.; Masking depends on stimulus fluctuations in ways steady-state models cannot predict.; Slow envelope fluctuations up to 16 Hz predict consonant-in-noise perception. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5575 (+2 more)
