A method of minimizing engine noise emitted from a motor vehicle air intake system. An objective function to be minimized, such as emitted engine noise, is selected. A model of a motor vehicle engine and intake manifold as an acoustic source is generated. Next, a model of required air induction system components is generated. A set of air induction system components and system dimensional constraints is selected. A model of the air induction system is then created given the generated models of the acoustic source and the required induction system components, the selected air induction system components and the system dimensional constraints to thereby minimize the objective function. The methodology of the present invention minimizes the guesswork associated with multi-component induction system design, as it ties all functions together into a model that can be easily manipulated as needed in response to changing design parameters.
