What causes temporal masking?

Temporal masking refers to masking (i.e., obscuring of one sound by another) that occurs when a signal and a masker are not presented simultaneously. Backward masking occurs when the masker follows the signal; forward masking occurs when the masker precedes the signal (Fig. 18.5).

What is the difference between frequency masking and temporal masking?

Auditory masking in the frequency domain is known as simultaneous masking, frequency masking or spectral masking. Auditory masking in the time domain is known as temporal masking or non-simultaneous masking.

How does masking effect perception of a signal?

If two signals that occur simultaneously are close together in frequency, the stronger masking signal may make the weaker signal inaudible. The masking threshold of a masker depends on the frequency, sound pressure level, and tone-like or noise-like characteristics of both the masker and the masked signal [61].

What is meant by the terms frequency and temporal masking of two or more audio signals?

What does the temporal masking mean? Dad: The frequency masking is caused when a low-tone sound makes the high-tone be heard difficult if there is a certain difference in tones between the two occurred at the same time. The masking occurs also when there is a certain time-delay between the two sounds.
