Abstract
A muffling device includes an acquisition circuit, configured to obtain reference sound wave information of a user. The muffling device includes a modulation circuit, configured to analyze an acoustic wave characteristic of the reference sound wave information to obtain a characteristic parameter of the reference sound wave information. The muffling device includes a muffling circuit, configured to generate compensated sound wave information according to the characteristic parameter of the reference sound wave information. The muffling device includes a correction circuit, configured to compare muffed sound wave information superimposed by the compensated sound wave information and the reference sound wave information with the reference sound wave information, and feed back a comparison result to the muffling circuit. The muffling circuit can adjust the compensated sound wave information according to a fed back comparison result. The muffling device includes an output circuit, configured to output adjusted compensated sound wave information.
