| Abstract: | A detail discusion is presented in the paper on the noise making propagation and its characterestic at a turbojet engine test bench. A Comparison of various design of noise control is made. The noise-reduction performance of thick or thing plate assembly which qonsists of bilayer metal plate unit with multiple tiny hole is also given in the paper. With useful first-hand data, the noise-reduction effect of a device on wide-frequeney-band, 140 dB(A) noise made during engine test is discussed. |
