Monaural masking release in random-phase and low-noise noise.

摘要: Two masking-release paradigms thought to involve across-channel processing are comodulation masking release (CMR) and profile analysis. Similarities between these two were explored by comparing signal detection in maskers that varied only degree of envelope fluctuation. The narrow-band-noise 10 Hz wide their fluctuations manipulated using the low-noise noise algorithm Pumplin [J. Acoust. Soc. Am. 78, 100–104 (1985)]. Masking conditions included classic CMR an on-frequency band, multiple (five) incoherent bands, or coherent bands. Detection was compared both random-phase (RPN) (LNN) maskers. In one set conditions, identical masker, yielding intensity discrimination task. Conditions RPN tonal signals resembled paradigm, whereas including LNN more closely analysis paradigm. Other may be considered hybrids. This combination provided a variety within- cues for detection. results suggest could based upon same stimulus perhaps perceptual processes.
