Abstract:
Acoustical evaluations were made of the Type II aircraft ground runup noise suppressors. The evaluations provide comparison of performance with and without installation of a diffusion screen in the exhaust stream. A description is presented of the suppressors reduction of the noise radiated by the aircraft to the far field, and the change in the noise environment for maintenance personnel resulting from enclosing the aircraft. The noise environment in the suppressors control and utility rooms during aircraft runup is described. The computed transmission loss is reported for the walls and doors and an estimate of the relative contributions of each noise transmission path to the suppressors far field noise is included. Author
