摘要

The report describes a program undertaken to investigate the noise characteristics of a 60 KW US (DOD) (DED) generator set, and reduce the noise to the lowest level attainable with a modification kit which would have minimum impact on set operation, performance, maintenance, size, weight and added cost. A suitable kit was developed to meet these requirements, installed on the set, and accomplished a noise level reduction from 93 dB(A) (standard set configuration) to 77 dB(A) (modified set configuration) measured from a distance of 25 feet from the center of the set.
