This study aims to improve the acoustic response of an automotive air intake system (AIS) using harmonics acoustics analysis system. Noise pollution imposes adverse health effects on human beings. One of the sources of noise pollution comes from the transportation sector. Combustion engines produce noise through the act of combustion during operation. Noise generated by the AIS affects the comfort and long-term health of humans during operations. The noise produced by the AIS can be reduced through the introduction to resonators. A baseline result was modelled through creating an internal cavity and running a harmonics acoustic analysis simulation in ANSYS. Transmission loss and frequency response data was analysed as well as the location of the noise through visual contour. Modifications to the baseline geometry were done through the addition of a resonator targeted at 197 Hz and the geometry was then analysed again through the same parameters with harmonics acoustics analysis. The results show the resonator is effective with the peak in noise at 197 Hz reduced but additional noise is introduced as a result of the addition of a resonator into the AIS.
