碩士 / 國防大學中正理工學院 / 造船工程研究所 / 92 / In recent years，with the progress of science and technology and a new line of environmental consciousness，the requirement of comforts on ship are increased. One of the major factors that affecting the comforts on ship is noise. Naval vessels often expose to the noise environment. The crew of noise not only interfere the talking communication but also cause the problems of endocrinopathy、headache、high blood pressure，so cause working efficiency to reduce，even threaten the security of personnel. The anti-submarine warfare capability is an important mission for naval battleships. Therefore，the self-noise prevention and cure of naval ships are very important and necessary tasks.
The purpose of this study is to investigate the predication and prevention of indoor noise. We first use the CATT-Acoustic indoor acoustic field simulation software to estimate the sound pressure distribution and reverberation time of a classroom. Next，the PULSE dynamic signal analysis system is used to measure the sound pressure and reverberation time of specific positions of the classroom. The estimated result are compared with the measurements to evaluate the accuracy of the software. The goal of the research is to build the capabilities of noise predication and prevention of the naval ship.
