Abstract:

The ability of listeners to discriminate between NoSπ and NoSo stimuli was measured as a function of signal-to-noise ratio. Three types of Gaussian-noise maskers were employed: 1) broadband (300 Hz to 6000 Hz) 2) high-frequency (2900 Hz to 6000 Hz) or 3) low-frequency (300 to 3100 Hz). The signal was a 3-kHz sinusoid. The overall patterning of the data supports the hypothesis that listeners can and do utilize "off-frequency" information to enhance binaural performance. The data also suggest that the off-frequency information within auditory filters centered above the frequency of the signal is especially salient.
