Spontaneous emissions respond to suppressors with a time constant near 15 ms
Evidence
In all suppression conditions tested, there were significant differences at the p < 0.05 level between suppression estimates obtained with short and long combined maskers. There was a significant difference between low-side suppression estimates obtained with short [M = 7.49, SD = 5.34] and long combined maskers [M = 4.54, SD = 5.57] at the 10-dB SL signal level [t (9) = 2.94, p = 0.017] and between short [M = 14.33, SD = 9.33] and long combined maskers [M = 8.25, SD = 8.42] at the 50-dB SPL signal level [t (9) = 3.41, p = 0.008]. — Dijk, Pim van, Physiology, Psychoacoustics and…, 940 (
