The design of a sound-proofed room has laid emphasis on the protection from outside noise and the sound-damping of inside noise, while ventilation and airconditioning have not been put into so much consideration.
In Yao Municipal Hospital the author studied the temperature and humidity of the sound-proofed room under air-conditioning in summer.
The following facts were obtained:
1) The noise of the air-conditioning machine was pardonably muffled by the silencer, which did not damage sound proofing and ventilation.
2) By ventilation the air humidity was reducced to 70%.
3) In case of the sound-proofed box in the sound-proofed room, the inside temperature was reduced to 0.03 to 0.09 degree per minute by keeping the door open.
