Abstract EN
Noise pollution is one of the most problems caused by internal combustion engines.
In this study, the reduction of noise by changing the orifice shapes and inserting tape is experimentally investigation.
The effect of orifice shape on noise reduction of silencer is presented.
The calculation of transmission losses and transmission coefficient of noise for different shapes of orifice by using MATLAB program is obtained.
In addition, the frequency for maximum and minimum losses is obtained.
The results showed that the use of the square orifice and helical tape were better options to reduce the noise in the Noise pollution is one of the most problems caused by internal combustion engines.
