Abstract
Measurements were made of the overall sound pressure levels and spectra of the noise generated by a T400-CP-400 UAC turboshaft power plant coupled to a CPW 0600-10000-041 mobile engine test trailer and operated outdoors. Running at maximum power the system produced overall sound pressure levels as high as 125 dB with the significant sound energy distributed between 300 and 8000 Hz, equivalent to an ISO noise hazard rating of 125.
