Underwater and Dive Station Work-Site Noise Surveys
Abstract
Previous work performed by the Naval Submarine Medical Research Laboratory (NSMRL) had developed in-water permissible continuous noise exposure guidance Work performed by the Navy Experimental Diving Unit (NEDU) measuring in-water noise levels produced by in-water tools to develop permissible exposure levels based upon applying in- air guidance and temporary threshold shift (TTS) data This study extends this previous work by obtaining in-water and in-air noise measurements and a total noise dose for Navy divers during actual diving operations using a portable sound level meter system capable of both in-water and in-air measurements Noise measurements were used to calculate Navy Occupational Exposure Limits (NOEL) and doses for both helmeted and Self-Contained Underwater Breathing Apparatus (SCUBA) divers The results of both in-water and in-air measurements were used to calculate total noise dose and these dosages were compared to existing guidance.
