Central masking: Some steady-state and transient effects

The contralateral threshold shift was investigated as a function of various parameters of the masking and masked stimuli. Because of a measured high acoustic attenuation between the ears, the threshold shift is interpreted as central masking. Both steady-state and pulsed maskers were used and their effect on the contralateral threshold was determined as a function of the masker intensity, the frequency difference between the masking and masked tones, the time delay from the masker onset, and the duration of an intermittent masker.
