目前,由于潜艇航速的不断提高,特别是核潜艇投入使用,仅靠舰艇进行搜潜反潜已不能满足需要。必须利用飞机进行反潜搜潜。但是由我国自行设计制造的、将用于搜潜反潜的“水轰——五”飞机机舱内的噪声强度高达110分贝左右。而声呐员工作舱内又无隔声消声设备,噪声对声呐信号的干扰较大,影响对信号的接收,缩短了反潜搜潜的作用距离。“水轰——五”飞机声呐员隔声帽就是为航空声呐员在搜潜反潜时,减少飞机噪声对声呐信号的干扰和保护声呐员的听力而研制的一种装具。隔声帽由隔声耳罩、罩垫、帽套、头弓和 At present, due to the continuous improvement of submarine speed, especially when nuclear submarines are put into operation, the search for potential anti-submarine ships alone can not meet the needs. Anti-submarine search must be carried out using aircraft. However, the noise intensity of the “water-bomber-five” aircraft cabin, which is designed and manufactured by China itself, will be used to search for potential anti-submarine ships at a high level of 110 dB. The sonar no sound insulation anechoic work cabin device, the noise on the sonar signal interference, affecting the signal reception, shortening the anti-submarine search potential distance. “Water h - five” aircraft sonar sound insulation cap is for the aviation sonar in the search submarine anti-submarine, to reduce aircraft noise on the sonar signal interference and protection of the sonar hearing a tool developed. Acoustic caps consist of acoustic earmuffs, shrouds, caps, head bows and
