Abstract

The invention relates to the technical field of hearing protection devices, in particular to a hearing protector and a noise reduction method thereof. The hearing protector comprises an ear hook and a control circuit board, the control circuit board comprises a digital filter, the ear hook comprises a loudspeaker and a reference microphone, and the reference microphone and the loudspeaker are respectively connected with the digital filter; and the loudspeaker is arranged at a position corresponding to the entrance of an ear canal. The hearing protector provided by the invention comprises the ear hook, so that the hearing protector does not need to be contacted with a human ear during use; the ear hook is provided with a component with an active noise reduction function, a small-range high-performance noise reduction area can be formed at an ear canal entrance, and a noise reduction method and function calculation processing are adopted to reduce and eliminate environmental noise transmitted to human ears. Therefore, the comfort level of a wearer is improved.

Description

technical field [0001] The invention relates to the technical field of hearing protectors, in particular to a hearing protector and a noise reduction method thereof. Background technique [0002] Hearing protectors are equipment for hearing protection of workers exposed to high noise environments. There are mainly two types of hearing protectors on the market today, one is a flexible in-ear earplug hearing protector, and the other is an earmuff hearing protector that wraps the entire ear. At present, these two forms of hearing protectors have comfort problems when worn for a long time, which leads to many cases that workers would rather endure high noise than wear hearing protectors. Therefore, it is necessary to develop a hearing protector with a comfortable wearing method. device urgently needs to be resolved. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0004]...
