This study aims to reduce the duct noise problem of air-conditioning system in hospital. Originally there were provided silencer in fan rooms and air ducts to reduce the noise level. So it is necessary to measure the noise level and to check satisfaction of the noise regulation in the rooms to provide suitable acoustical comfort. And countermeasures to reduce the noise were adopted. The result of before and after countermeasure were compared with dB(A), NC. |
