abstract

This paper describes the step-by-step procedure involved in solving a noise-control problem associated with the use of a J47 turbojet as a fixed-plant turbine-generator. Noise-reduction requirements for the turbine exhaust and intake are computed to satisfy both a hearing-loss criterion and a speech communication criterion. An impervious enclosure or a resilient wrapping, a lined 90-deg bend, the directive nature of one of the sources, and a muffler of acoustic baffles are utilized in solving the problem.
