Masking of narrow band noise by periodic pulse trains of different repetition rates and by synthetic vowels was investigated in this paper. Results indicate that the masking process is controlled by limited spectral resolution in the low-frequency part of the masker and by limited temporal resolution in the high-frequency part. The results are also discussed in connection with auditory correlates in speech signal processing.
