There are many kinds of earplugs and earmuffs in terms of personal protection against noise. But are not ideal, (stimulate the ear canal skin dermatitis or sound insulation is not good). In order to solve this problem, we are trying to produce a kind of earmuffs with soundproof effect and hygienic requirements.
