Binaural amplitude discrimination and the binaural masking-level difference. 1991

G B Henning
Department of Experimental Psychology, Oxford, U.K.

Under certain conditions, amplitude discrimination is not a monotonic increasing function of signal-to-noise ratio. The non-monotonicity arises when the tones to be discriminated are presented 180 degrees out-of-phase at the observer's ears and just above their detection 'threshold' in noise that is in-phase at the observer's ears, and with 2-6-dB differences in amplitude.
