The present invention relates to a hearing protector for noise reduction control, which comprises a bar body made of soft material to be inserted into an ear canal, and at least one thin film-containing hearing protector formed annularly on the outer periphery of the body, ,A noise guide hole formed to penetrate the body in a longitudinal direction of the body； an end of the noise guide hole being fixedly fixed to the noise guide hole, wherein an insertion hole communicating with the noise guide hole is formed therein, And a plurality of acoustic filters that are inserted into the insertion holes of the adjustment body to close the insertion holes of the adjustment body to reduce noises. As a result,It is possible to appropriately control the degree of noise reduction introduced into the user's ear through the body by appropriately controlling the degree of noise reduction in the body constituting the hearing protector in consideration of the use situation of the user, The external sound source is induced to be audible and can be effectively used in construction sites or military units where noise is frequently generated.In addition, the pair of hearing protectors are connected to each other through the connecting means and the connecting line, thereby providing the user with convenience of storing and managing the hearing protector, thereby minimizing the loss of the hearing protector.Also, the hearing protector can be connected to the control line and the length of the control line can be easily controlled by the reel holder, so that the user can easily carry out recovery and storage of the hearing protector automatically by operating the reel holder, It is possible to effectively prevent contamination of the reel holder, and also it is possible to easily attach the reel holder to the user's safety helmet and upper garment through the attaching means, thereby ensuring ease of use of the product.본 발명은 소음 저감 조절용 청력보호구에 관한 것으로, 그 구성은 외이도에 삽입되도록 소프트 재질로 된 봉 형상의 몸체와, 그
