| Résumé | As part of a programme designed to reduce the jet noise Emitted from the Engine Laboratory, a baffle-type silencer was installed in the inlet to No. 3 test cell. The purpose of this investigation was to evaluate the transmission loss across the silencer, as well as the resulting noise reduction at a point 30 feet in front of the inlet. Because there was no engine in the cell at the time of installation, the silencer was tested using an 1 1/8-inch-diameter air jet as noise source. Some time after completion however, a few rough over-all sound -pressure measurements were made with an Olympus engine in the cell. |
