Abstract
It has been suggested that external noise maskers, like sensorineural hearing loss, have a linearizing effect on cochlear function and that external noise maskers can be used to simulate sensorineural hearing loss. To test these hypotheses, cubic‐difference‐tone (CDT) behavior was measured in normal hearing listeners using a forward‐masking paradigm for sinusoidal primaries presented in quiet and in the presence of low‐pass, high‐pass, and broadband noise. The noise was presented only during the primaries and could be considered as an additional forward masker. None of the noises used affected CDT behavior in a way that would support the hypothesis that noise has a linearizing effect on cochlear function. The range over which cubic difference tones could be measured was shifted by the amount that the thresholds for the primaries were shifted, but otherwise CDT behavior was similar to that observed in quiet. In contrast with results reported for persons with high‐frequency sensorineural hearing loss, high‐...
