Temporal Masking

Temporal masking is the characteristic of the auditory system where sounds are hidden due to maskers before or even after that time. The effect of masking after a strong sound is called post-masking, and can be in effect up to 200 ms. The pre-masking, where a sound actually is masked by something which appears after it, is relatively short and may last up to 20 ms. An illustration of this can be found in Fig. [*].
