Test of Bendix Air Filters Used as Mufflers.

Abstract

Excessive noise, coming mainly from air supply and exhaust lines, has recently become recognized as a serious hazard to hyperbaric chamber personnel. A Bendix air filter no. 057619 was tested by the Navy Experimental Diving Unit as a potential muffler for these systems. The filter was found to produce a 30dbA reduction in the sound level produced by the air supply line in EDU's no. 5 recompression chamber. The filter, being combustible, was, however, judged a fire hazard and work with it has been terminated in favor of work with all metal filters and silencers. (Author)
