Abstract
Reverberation time within studio ’ s decor is changed because of addition of its surface to the overall surfaces of the stu dio and also the additional absorption of its materials. It seems reverberation time changes due to studio ’ s decor is little because surface of the decor is small in comparison with the overall surfaces of the studio and surface has an important role in room constant and therefore in reverberation time. But these changes do not only depend on added surfaces and their absorption. Reverberation time is also dependent on shape of the decor and sometimes . It can decrease the effects of added surfaces which are used to increase the reverberation time. In this paper , a standard television studio is de signed and implemented by using ODEON and 12 different decor which their dimensions and materials are similar to the actual ones, are applied inside the studio. Then studio ’ s decor effects on reverberation time of the studio are com puted, compared and analyzed.
