Abstract

A two-way radio system for the flight deck of aircraft carriers has been developed by the Navy Electronics Laboratory. The system connects mobile deck personnel wearing helmet transceivers with two control centers located in the island structure. Because of the high noise levels in which the helmet transceivers had to operate, special attention was given to noise exclusion and speech processing techniques. This paper presents: (1) speech processing techniques specified for the system, (2) performance of the acoustical components used in the helmet transceivers, and (3) results of an operational evaluational of the system as installed aboard an aircraft carrier. The evaluation indicated that talkers and listeners could communicate effectively in jet aircraft noise up to 130 db SPL and that users of the system were well satisfied with the noise exclusion and speech intelligibility.
