High-level psychophysical tuning curves: simultaneous masking by pure tones and 100-Hz-wide noise bands.
Simultaneous-masked psychophysical tuning curves were obtained from normal-hearing listeners using low-level (20-25 dB SPL) probe tones in quiet and high-level (60 dB SPL) probe tones, both in quiet and in the presence of a broad-band background noise. The background noise was introduced to eliminate combination tones or combination bands and other off-frequency listening cues that exist at hig...
متن کاملAsymmetry of masking between complex tones and noise: partial loudness.
This experiment examined the partial masking of periodic complex tones by a background of noise, and vice versa. The tones had a fundamental frequency (F0) of 62.5 or 250 Hz, and components were added in either cosine phase (CPH) or random phase (RPH). The tones and the noise were bandpass filtered into the same frequency region, from the tenth harmonic up to 5 kHz. The target alone was alterna...
متن کاملDetection and F0 discrimination of harmonic complex tones in the presence of competing tones or noise.
Normal-hearing listeners' ability to "hear out" the pitch of a target harmonic complex tone (HCT) was tested with simultaneous HCT or noise maskers, all bandpass-filtered into the same spectral region (1200-3600 Hz). Target-to-masker ratios (TMRs) necessary to discriminate fixed fundamental-frequency (F0) differences were measured for target F0s between 100 and 400 Hz. At high F0s (400 Hz), asy...
متن کاملMasking of the signal for lateralization of tones
Elliott and Wilbanks (1980) have shown that when listeners attempt to localize a tone in noise, the "signal" for lateralization is the change in the interaural phase between tone plus noise and the interaural phase of the noise alone. This "signal" can be masked by increasing the level of the noise and by reducing the interaural correlation of the noise. Data are presented showing how the maski...
متن کاملTones and non-tones in Kammu dialects
This is apreliminary report on the phonetic interaction of tone and consonant voicing in K m u , a language where some dialects use Fo for producing distinctive word tones, while others do not have tones but rely on the contrastive voicing of initial consonants to distinguish words which tonal dialects distinguishes with tones. Speakers of non-tonal dialects produce no significant Fo diflerence...
