Improvements in Underwater Voice Communication.
Abstract
Various methods and techniques were investigated for improving voice communication between diver/swimmers, within closed environments, and under adverse conditions resulting from water immersion. Improvements were sought in the reduction of channel noise, increased signal reception, reduced gas/pressure distortion, expansion of the useful auditory channel, and clearer diver/swimmer articulation. In order to accomplish these tasks, it was necessary to develop methodologies for better assessment of transducers and transmission channels. Furthermore, studies were conducted to determine the effect of word sequencing on message reception and the effect of time/frequency distortion on the transmission of prosodic feature information.
