Abstract

Enclosures are a very common way to reduce noise emissions from machinery. However, enclosures display complex acoustic behavior that is difficult to predict. Boundary element simulation was used to better understand the airborne transmission path for a partial enclosure. Sources considered included a point source and a diesel engine. Insertion loss was used as the performance measure to evaluate the effect of several different enclosure configurations. Results indicate that the most important factors affecting enclosure performance are the opening size, amount of absorption, and the relationship between the source directivity and the opening location. It is notable that insertion loss was less sensitive to enclosure or source size, or to absorption location.
