Abstract

This study deals with design and application of silencer to reduce the exhaust noise, especially at the low frequency range below 200 Hz which is main contribution for the bridge wing noise and the external noise of ships. The designed silencer is composed of side branch resonator, Helmholtz resonator and absorbing material. The resonating frequencies of resonators are set to be the firing order frequencies of the generator engine. Based on the on-board measurement result, it is verified that the designed silencer can effectively reduce the exhaust noise of generator engine.
