Abstract
A method of tuning a vehicle includes measuring a plurality of inlet and outlet frequency responses at the inlet and outlet ports, respectively. The inlet and outlet responses each include an amplitude response and phase response. The method also includes determining inlet and outlet transfer functions that include amplitude and phase responses. An interior noise spectrum is determined and the engine air in/out system is modified based on the interior noise spectrum to result in a different interior noise spectrum.
