Acoustic Energy Analysis and Noise Control Design of Engine Control Rooms on Ships
摘要
Abstract
It is very difficult to control the noise of engine control rooms (ECR) on ships. In this paper, based on statistical energy analysis (SEA) method and using VA One software, the SEA model of a platform support vessel is established. Cabin noise values are predicted and compared with the measured values. The acoustic energy transferring into the ECR from all its connected sub-systems is analyzed and its acoustic energy composition and sequencing type are obtained. The effect of air-borne noise and structure-borne noise on the ECR is determined and used as the basis of vibration and noise control. According to the noise frequency spectrum characteristics of the ECR and the NCT function of the software and using acoustic package design method, noise reduction processing is successfully carried out with different material compositions for each side of the ECR. This study provides a reference method for noise control of ship cabins.关键词
