Abstract

Because of the space constraints problem in practical engineering work, there is a growing need to optimize the acoustical performance of a sound-proofing device within a fixed space. The optimal mechanism used in adjusting either the plenum’s chamber or an internal sound absorber has been ignored. In order to maximize the acoustical performance of a plenum, a case study of depressing a diesel engine noise by using three kinds of optimally shaped multi-chamber acoustical plenums lined with three kinds of multi-layer sound absorbers is introduced. On the basis of constrained weight and space in the plenum, a low cost optimal acoustical mechanism was assessed using an artificial immune method (AIM). Consequently, this paper provides a quick, economical, and effective method for reducing noise levels by optimally designing shaped multi-chamber acoustical plenums lined with multi-layer sound absorbers using an artificial immune method
