Book Description
The attenuation characteristics of the muffler used in the demonstration of light airplane noise reduction were investigated on the ground dynamometer stand at the Langley full-scale tunnel. Sound, back pressure, and engine power output were measured. The ground tests indicated that a reduction of 10 to 15 decibels was to be expected from this muffler.
