Abstract
Low frequency exhaust noise of marine diesel engine is one of the most important noise sources in vessels. However, conventional absorptive silencers are limited because the absorptive material is not effective in low frequency range. In the paper, exhaust noise control of marine diesel engine has been studied by using the resonator type silencer, which was composed of concentric hole-cavity resonators. The acoustic performance of the resonator type silencer was verified by the insertion loss measurement considering flow effect. Consequently, its high performance, about
