摘要：
This study represents an investigation of the COMSOL Finite Elements (FE) capabilities of simulating noise reduction techniques. This general purpose FE code has an acoustics module, from which the present study investigates one type of muffler used in the automotive industry. A comparison is made between a reference design model and an improved model with a number of holes in the two ducts of the muffler. The results indicate that such a design tool can be successfully used in other applications concerning noise reduction such as exhaust nozzles.
