Description
Изобретение относитс к вспомогательному снар жению авиатехнического состава и служит дл индивидуальной защиты органов слуха от мощных авиашумов, создаваемых турбореактивными и турбовинтовыми двигател ми, во врем их обслуживани или испытаний.The invention relates to the auxiliary equipment of an aerotechnical composition and serves for the individual protection of hearing organs from the powerful aerosols created by turbojet and turboprop engines during their service or testing.
Предложенные звукозаглущающие наушники отличаютс от известных аналогичных устройств, например, от противошумов системы Живара , Гроньо и др., тем, что они выполнены из двух частей коробчатой формы, вставл емых одна в другую с зазором, заполненным пластелином . Дл создани уплотнени наушники снабжены по борту кольцом из пористой резины. Звукозаглушающие наушники могут устраиватьс в утепленном зимнем шлеме, в неутепленном шлеме, который нос т весной и осенью, или делатьс с оголовьем дл лета. Предложенные наушники могут быть использованы и на других предпри ти х, работающих в услови х сильного шума.The proposed sound-pluggable headphones differ from known similar devices, for example, from Zivara, Grono et al. System noise, in that they are made of two box-shaped parts inserted one into the other with a gap filled with pasteline. To create a seal, the headphones are equipped with a ring of porous rubber around the board. Sound deafening headphones can be arranged in a warm winter helmet, a non-insulated helmet that is worn in spring and autumn, or made with a headband for summer. The proposed headphones can be used in other enterprises operating in conditions of strong noise.
На фиг. 1 схематически изображен звукозаглушающий наушник и прин ты следующие обозначени : / - чашка внутренн , 2 - чашка наружна ,5 - лента, 4 - набивка, 5 - наполнитель (пластилин), 6 - резиновое кольцо, 7 - чехол, 8 - нрокладка кольца.FIG. 1 shows a sound-attenuating earpiece and the following notation is used: / - inner cup, 2 - outer cup, 5 - tape, 4 - padding, 5 - filler (plasticine), 6 - rubber ring, 7 - cover, 8 - flat ring.
На фиг. 2 и 3 показано оформление наушников в шлеме и с оголовьем .FIG. 2 and 3 shows the design of the headphones in a helmet and with a headband.
