Title: Sound Level Testing of the Standard USN MK V Air and Helium-Oxygen Diving Helmets.
Author: Reimers, SD; Summit, JK
Abstract: Nine standard USN Mark V Air Diving Helmets and two standard USN Mark V Helium-Oxygen Diving Helmets were subjected to sound level testing on two specially built acoustical manikins at the Navy Experimental Diving Unit. The sound levels existing in the helmets were found to be into the hearing damage risk levels under nearly all the conditions tested. Wide variability in the measured sound levels was found to exist from helmet to helmet. The relationship of the test results to other similar work is discussed. Several possible ways of reducing the measured sound levels are presented. (Author)
