Research on acoustic environment optimization design of ship multi-functionnal conference room

In order to optimize the acoustic environment of the multi-functional conference room of the ship, the ODEON software is used for simulation calculation, and the sound absorption performance test of the sound-absorbing material is tested in the impedance tube test system. The reverberation time T30 was used as an evaluation index. A comparative study of different conference room ceiling structures was conducted. The results show that the alumina blanket sound-absorbing material is used as the conference room ceiling structure, the reverberation time of the ship multi-functional conference room is reduced from 1.3s to 0.4s, which achieves better acoustic environment optimization effect.
