PURPOSE:To enable execution of effective deodorization of air passing through the inside of air supply and exhaust ducts for ventilating a soundproof room (soundproof box) being excellent in airtightness, by sticking a deodorizing agent on the inner peripheral surfaces of the ducts. CONSTITUTION:The floor, ceiling and surrounding walls 2 of a soundproof room 1 used for playing of a musical instrument or others are constructed of a soundproof material and made to obtain excellent sound-insulating and acoustic performances. An outlet 3 and an inlet 4 are provided in the ceiling surface in the room and an air supply duct 5a is connected to the outlet 3, while an exhaust duct 5b is connected to the inlet 4. Each of the air supply and exhaust ducts 5 (5a, 5b) is made to have a lining structure prepared by sticking a glass wool sound-absorbing material 22 and a deodorizing member in a laminated state on the inside of a duct main body 21 formed of an iron plate or the like. This deodorizing member is constituted of cloth 23 holding the sound-absorbing material 22 and a deodorizing agent 24 stuck on the cloth 23, and as the deodorizing agent 24, a metal compound such as a metal phthalocyanine derivative, a crystal substance thereof or activated carbon is used. |
