Intelligibility Evaluation of the Tethered Diver Communications System (TDCS). Part II. Human Engineering Evaluation of the TDCS

摘要

This report consists of two parts: Part I; An evaluation of the voice intelligibility of the Tethered Diver Communication System (TDCS) was undertaken during a 1000 FSW Saturation Dive conducted in the Ocean Simulation Facility (OSF) of the Navy Experimental Diving Unit (NEDU). The Griffiths (1967) version of the Modified Rhyme Test (MRT) was used as the evaluation instrument during this testing. The evaluation provided basic TDCS intelligibility data with a variety of diving rigs at a number of different depths. Part II; A human engineering evaluation of the TDCS was also conducted on the 1000 FSW Saturation Dive. Questionnaires were completed by most of the personnel closely involved with the day to day operation of the equipment. Recommendations were made concerning future modifications to the system.
