Noise Exposure Evaluation in Radio Terminal Set AN/TRC-112, 21 June 1979.

Abstract

Noise levels in two radio terminal sets, AN/TRC-112, were measured to determine if the operators are exposed to noise hazardous levels and to define noise control approaches if required. The noise levels in the two terminal sets were below the US Army 85 dB, A-weighted hearing conservation criterion. The character of the noise was judged to be annoying because of an audible high frequency whine. Some noise control is relatively easily attainable but reductions of more than about 4 dB and elimination of the whine will require some redesign of the power amplifier. (Author)
