Earmuff: A device, shaped like a headset, that is mounted on a bow to cover the ears to attenuate noise. The noise attenuation of ear muffs can reach 10-40 decibels, which is suitable for environments with high noise, such as processing workshops of shipyards and metal structure plants, engine test benches, etc. In recent years, some countries have also fixed earmuffs on welding masks or used them together with communication headphones or earphones. Earplugs and earmuffs can be used separately or in combination. The combined use can increase the noise attenuation by 5~15dB compared with the single use.

The utility model relates to an ear protector which can cover the whole ear. The noise proof earmuff is composed of two round shells connected by the bow frame. The shell is attached with sound absorbing materials and sealing washers, which are shaped like earphones as a whole. It is suitable for high noise environment, and the sound attenuation can reach 10-30dB. It can be used alone or in combination with earplugs. Suitable for people with various ear types. Easy to take off; But it feels stuffy and hot after a long time of use.
