Lateral Suppression and Loudness Reduction of a Tone in Noise
Several masking experiments were performed with a 1000-Hz test tone and a masker consisting of a 1000-Hz tone plus noise. In two experiments using a non-simultaneous masking technique (e.g., forward masking), it was found that a tone-plus-noise masker may be considerably less effective in masking than the tonal masker alone. This effect of noise on the masking effectiveness of a tone appeared to correspond quantitatively with the effect of noise on the loudness of the tone. It is suggested that these noise-induced reductions of both the loudness and the masking effectiveness of a tone reflect the operation of one and the same mechanism: lateral suppression of the tone by the noise. The results of further experiments with bands of noise added to the 1000-Hz-tone illustrate that the supposed suppression acts mainly “one-directional”: from higher to lower frequencies. The present data on tone-plus-noise maskers agree well with previous data on two-tone maskers and with related electrophysiological observations on “lateral inhibition” in single-unit responses.
