Abstract

The disclosure provides a muffling device and a muffling method, a communication device and a wearable device, relating to the technical field of communications. The muffling device comprises: an acquisition module configured to acquire reference acoustic wave information of a user; a modulation module configured to analyze the acoustic wave characteristics of the reference acoustic wave information to obtain characteristic parameters of the reference acoustic wave information; a muffling module for generating compensated acoustic wave information according to the characteristic parameters ofthe reference acoustic wave information; a correcting module configured to compare the muffed acoustic wave information obtained by superimposing the compensated acoustic wave information with the reference acoustic wave information with the reference acoustic wave information, and feedback the comparison result to the muffling module; and an output module configured to output the adjusted compensated acoustic wave information, wherein the muffling module is further configured to adjust the compensated acoustic wave information according to the fed back comparison result. The disclosure is capable of reducing the impact of the call volume on the surrounding environment and implementing a secure call.

Description

technical field [0001] The present disclosure relates to the technical field of communication, and in particular to a noise reduction device and method, communication equipment and wearable equipment. Background technique [0002] With the development and progress of society, people pay more and more attention to the confidentiality of information, but in the process of telephone communication, personal privacy or company secrets are often revealed unintentionally, and the volume of the call is too loud to disturb the people around. [0003] Based on the problem of excessive call volume, the traditional method is mainly to artificially weaken the sound from the two aspects of the sound source and the sound propagation path, such as avoiding crowds to communicate in uninhabited areas, or actively lowering the sound, etc., but The former requires a specific environment, and the latter will affect the quality of the call and the accuracy of communication due to the low voice, a...
