Abstract
This paper presents a noise eliminating duct with a structure that controls the direction of sound reflection on a wall. Controlling the reflection direction can increase the number of reflections and reduce the reflected sound. The optimized shape of a noise eliminating duct was created through optimization method using shape expression method by Radial Basis Function Network and acoustic analysis by boundary element method. The simulation result of the sound pressure level distribution of radiated sound for optimized shape shows bias in the direction as designed. This result confirms the usefulness of the design methodology.
