Relations between notched-noise suppressed TEOAE and the psychoacoustical critical bandwidth.
Narrow-band transitory evoked otoacoustic emissions (TEOAE) were recorded for nine normal hearing subjects in the presence of a broadband tone complex suppressor. Introducing a spectral notch at the frequency of the narrow-band stimulus causes the suppression effect to decrease, the more so the wider the notch. This decrease in suppression permits an estimate of the size of one critical band. O...
متن کاملVariable-duration notched-noise experiments in a broadband noise context.
A variable-duration notched-noise experiment was conducted in a noise context. Broadband noise preceded and followed a tone and notched noise of similar duration. Thresholds were measured at four durations (10, 30, 100, and 300 ms), two center frequencies (0.6, 2.0 kHz), and five relative notch widths (0.0, 0.1, 0.2, 0.4, 0.8). At 0.6 kHz, 10-ms thresholds decrease 6 dB across notch widths, whi...
متن کاملComparison of auditory filter shapes obtained with notched-noise and noise-tone maskers.
The notched-noise method has been widely used to estimate the shape of the auditory filter. Results obtained using this method may be influenced by combination bands produced by the interaction of components within the upper band of noise in the notched-noise masker. To assess the possible effect of such combination bands, results were compared for two types of masker: A notched noise, as used ...
متن کاملNotched-noise precursors improve detection of low-frequency amplitude modulation.
Amplitude modulation (AM) detection was measured with a short (50 ms), high-frequency carrier as a function of carrier level (Experiment I) and modulation frequency (Experiment II) for conditions with or without a notched-noise precursor. A longer carrier (500 ms) was also included in Experiment I. When the carrier was preceded by silence (no precursor condition) AM detection thresholds worsene...
متن کاملThe effect of notched noise on fl icker detection
20 Flicker perception was investigated using two-alternative forced-choice detection and discrimination tasks with four different 21 types of external noise: (1) broadband noise, (2) 5-Hz notched-noiseVbroadband noise with a 5-Hz band centered on the 22 signal frequency removed, (3) 10-Hz notched-noise, and (4) no external noise. The signal was a burst of 10-Hz sinusoidal 23 flicker presented i...
