함정 격실에 적용되는 흡음재와 잔향시간에 따른 실내 소음 분석
Investigation of the Indoor Noise of Naval Vessel according to the Sound Absorption and Reverberation Time in a Cabin
- 발행 : 2010.10.27
초록
The sound field can be classified to the direct and reverberant sound field. If the sound absorption material in a room is not applied sufficiently, the reverberant sound field increases and the sound pressure in a room also increases when the sound source exists in a room. Therefore, the reverberation time should be controled in order to reduce the reverberant sound as well as sound pressure level in a room. Even though the reverberation time is specified and researched widely in architectural engineering, it is rarely performed in a marine engineering. Therefore, in this research, the reverberation time in a navel vessel is researched related to the noise reduction in a cabin.
