Detailed measurements of tone-on-tone masking in the chinchilla with the signal (f2) higher in frequency than the masker (iff1) were obtained with 50-dB SPL maskers of 1000 and 1500 Hz. Two regions of lower thresholds (notches) were found for each masker. The masker-notch interval was independent of masker frequency for one of these notches, but dependent on frequency for the other. The latter notch was thought to be due to the detection of 2f1-f2 combination tones and to provide additional evidence for relatively poor frequency resolution in the chinchilla.
