Forward masking requires maskers with similar frequency components and high intensity

Evidence

Forward masking occurs when the masker is high in intensity and has frequency components similar to the signal. In order to produce masking, forward maskers must have similar frequency ranges to the stimulus they are masking. The temporal relationship between the two sounds is also relevant, and forward masking decreases as the signal is moved farther away from the masker in time. The decrease in detection threshold as the signal and masker are increasingly separated is the release from forward masking. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1028
