Postmasking can last up to 200 milliseconds after a masker ends

Evidence

The excitation level depends not only on critical-band rate but also on time. Speech sounds, for example, contain strong temporal variations produced not only by the plosives themselves but also by the pauses necessary before the plosives. In the same way as we used the masking level versus frequency patterns for transformations into excitation level versus critical-band rate patterns, masking level versus time patterns can be used. As explained in Sect. 4.4.3, postmasking plays an important role. It can last up to 200 ms, but the decay depends on the duration of the masker. Consequently, sets of data representing masking level versus time patterns for post masking have to be used in a way similar to masking level versus critical-band rate patterns to produce excitation level versus critical-band rate patterns. It may be argued that this is a relatively complicated procedure. The resulting excitation level versus critical-band rate versus time pattern, however, contains the information used by the hearing system to recognize and understand speech. — Professor Dr.-Ing.
