1.One sound can make it impossible to hear another or one sound may shift the apparent loudness of another
2.In some situations an otherwise clearly audible sound can be masked by another sound.
3.For example, conversation at a bus stop can be completely impossible if a loud bus is driving past.
4.This phenomenon is called masking. If one tone is masking another, the effect depends on the separation in frequency.
5.A weaker sound is masked if it is made inaudible in the presence of a louder sound.
6.Masking can also happen if the tones do not happen simultaneously.
7.Masking effect led to the notion of critical band, that is, a given frequency surrounded by a band of frequencies.
