耳罩耳罩是两只能覆盖住耳廓的壳体,用弓形连接件连在一起,以便于佩戴使用,降低噪声对人体听觉的影响。为了加强耳罩与佩戴者皮肤接触部位的密封性,改善使用者的舒适度,在壳体的周边包覆着内装有泡沫塑料或液体的密封垫,其表层一般采用仿鹿皮,有良好的弹性。
Earmuffs Earmuffs are two housings that cover the auricle and are connected together by arcuate connectors to facilitate their wearing and reduce the effects of noise on human hearing. In order to enhance the contact between the earmuffs and the wearer’s skin and improve the user’s comfort, the periphery of the shell is covered with a gasket filled with foam or liquid. The surface of the gasket is generally mopped with a good elasticity.
