Title: Evaluation of Commercially Available Underwater Communicators for Use with the MK I MOD O and MK 12 SSDS (Surface Supplied Diving System) in the Air Mode.
Author: Trukken, SG; Pelton, JD
Abstract: In March and April 1984, the Navy Experimental Diving Unit tested four, three diver, four wire, helium speech unscrambler (HSU) capable commercial underwater communicators. The goal was to recommend one or more of the following commercial communicators for Navy approval for use in the air mode only: a) EFCOM HSU-1500; b) HELLE Model 3315; c) HYDROCOM UDC-225; d) AMCOM III Model 2830H. Only the HYDROCOM, manufactured by Hydro Products, satisfied required communication intelligibility using the Modified Rhyme Test (MRT) as the evaluation criteria during shallow manned in-water testing. Human engineering aspects were satisfactory. The HYDROCOM unit suffered no material failures during testing. The Hydro-Products, HYDROCOM UDC 225 is considered to be a reliable and effective means of communication for surface supported diving operations. Key words: Hardwire Communicators, MK 12 Communications, MK I Communications.
