Summary:

The turbocharger air intake noise during transient condition like wide open throttle affects the passenger ride comfort. This paper aims to study an optimized design of multi-chamber perforated resonators to attenuate this noise. The noise produced by turbocharger in a test vehicle has been measured to find out the noise spectral characteristics which can be used to design the acoustic targets including the amplitude and frequency range of transmission loss. To meet the acoustic targets, the structural parameters of the resonators are optimized based on the genetic algorithm and two-dimensional prediction theory of the resonator transmission loss. The optimized resonators are installed on the test vehicle to verify the actual noise reduction effect. The results suggest that the broadband noise has been eliminated and subjective feelings are greatly improved
