摘要：
The invention relates to medical engineering, in particular for PPE from the harmful effects of acoustic noise on the body worker. The object of the present invention is to improve the hygienic and ergonomic characteristics of the earphone due to redistribution of pressure between temporal and parotid regions. This object is achieved in that the antinoise headphones comprising a headband, the ends of which two insulating plates fitted with elastic cushions filled with an elastic sound-insulating material, each of the elastic rollers is divided into two equal temporal and BTE sectors, isolated from each other, BTE sector elastic each roller of cups filled with sound insulating elastic soundproofing material 30 ÷ 60% less dense than the temporal sector and division of the temporal plane and resilient shaft BTE sectors Single each of the sound-insulating plates is inclined at an angle of 25 ° ÷ 45 ° to the plane passing through the headband and the insulating plates, wherein the temporal sector elastic rollers oriented in the same side of this plane, and BTE - to another. The technical result of the invention is the prevention of disturbances of local blood flow and lymph flow and removal discomfort during prolonged operation of the headphones associated with an equally high pressure of the insulating ridges on the BTE and temporal area. The proposed technical solution can be used noisy production workers, for example in wood and metal working shops, gas compressor stations, etc., Mainly in those cases where the production process requires a long wearing hearing protectors. 1 n.p.f.Изобретение относится к медицинской технике, а именно к средствам индивидуальной защиты от вредного воздействия акустических шумов на организм работника. Задачей настоящего изобретения является улучшение гигиенических и эргономических характеристик наушников за счет перераспределения давления, между височной и околоушной областями. Указанная задача достигается тем, что в противошумных наушни
