Estimation of Contributed Noise Levels of Diesel Engine Components from Vibration Measurements 750160
An experimental technique to estimate the contributed noise levels of diesel engine components is presented. The technique predicts the contributed noise level in a reverberant acoustic environment from vibration measurements made on the surfaces of the engine components and the use of simple acoustic radiation theory. An experimentally determined value of the radiation efficiency is used in calculating the contributed noise levels. Experimental results are presented for a high speed Vee form engine. Also discussed are other techniques used to assess contributed noise levels of diesel engine components.
