Discarding high-power segments suppresses subject-generated noise in otoacoustic recordings

Evidence

The signal was then segmented into 1-sec analysis windows (1-Hz frequency resolution) with a step size of 250 ms. Half of the segments with the highest power were discarded in order to reduce the impact of subject generated noise. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5766
