Masking effectiveness depends on masker-signal power, frequency, and timing relationships

Evidence

The results from Hawkins and Stevens (1950) illustrate a small, but robust, effect of signal frequency. However, we can better observe the relationship between the frequency of maskers and the frequencies of the signals when experiments are conducted under variable frequency conditions. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 461
