This paper is represented study on the robust design of an intake system using a transmission loss and a frequency weighting function. First, transmission loss is measured to obtain the performance value of noise reduction for the intake system. The robust design parameters of an intake system are extracted by adapting a cost function with the taguchi method. Subsequently, the frequency weighting function is developed using subjective evaluation where 6 special engineers participated in the experiment. Finally, a comparative work between the proposed frequency weighted optimal design and unweighted optimal design of the transmission loss at part condition is undertaken. Here, overall level of transmission loss at current and each optimal condition are presented to validate the effectiveness of the proposed methodology.
