Abstract: The characteristics of interval exhaust noise and structure of mufflers for effectively controlling the noise are analysed. The model of aerodynamics in controlling the noise is established and is thoroughly analysed numerically and is verified experimentally. The theoretical basis is provided for muffer design in controlling the noise.

Key words: Aerodynamics, Exhaust noise, Numerical analysis, Test
