This paper is concerned with a computer simulation for the optimal active control of exhaust noise by using the boundary element method for analyzing two-dimensional acoustic field problems. It is assumed that the primary noise source is known and that the exhaust noise is radiated into the infinite acoustic field. The acoustic field is computed using the boundary element method for pure sound with a particular frequency, and the optimal set of parameters corresponding to the vibrating state of a secondary sound source and the shape of exhaust pipe are determined using the standard optimization technique. After the computational results for pure sound from 50 Hz to 500 Hz are shown, simulation is also carried out for a more realistic model of noise including two sounds of different frequencies.
