Effect of Noise at One Ear on the Detection of Signals at the Other Ear
B. E. Mulligan, William A. Wilbanks · The Journal of the Acoustical Society of America · 1965
Detection of a tonal signal in noise at one ear improves in proportion to the level of correlated noise in the “off” ear up to the point of equal noise levels in the two ears. A given level of correlated noise at the “off” ear produces a nearly constant improvement in detection over monaural masking independent of the signal-to-noise ratio in the ear receiving the signal. A given level of uncorrelated noise at the “off” ear, however, has the opposite effect. It produces a nearly constant decrease in detection over the monaural condition for various signal-to-noise ratios in the “on” ear.
