Auditory adaptation, short exposure time under strong noise, hearing threshold increased by more than 10dB, can recover after leaving the noise environment for a few minutes. It is a phenomenon of change in auditory perception caused by the action of auditory stimuli on the auditory organs for a longer period of time. When this phenomenon occurs, it is generally manifested as a decrease in the perception of the stimulus sound and its frequency similar to the sound, but this decrease is generally temporary, not long after the stimulus sound stops acting, the perception of the auditory organs will return to normal. Some studies have shown that auditory adaptation can occur in both ears when sound is applied to only one auditory organ. This suggests that the mechanism of auditory adaptation is central. If the auditory organ is subjected to a strong auditory stimulus for a long period of time, the resulting decrease in auditory perception often takes a day or night or even a few days to recover.
