Abstract
A systematic study [1], recently conducted at the NRC has verified most of the fundamental assumptions made when using the mobility approach for direct attached gypsum board. These assumptions need to be verified for the more complex and practical situation of gypsum board mounted on resilient channels (RC's). This paper, the first of two, examines assumptions relating topower flow as a function of position and number of fasteners between the gypsum board and RC's. Also considered is if the power transmitted by a rotational component of the stud is negligible compared the translational component. The second paper [2] examines further assumptions and gives estimates of the change in radiation efficiency and acoustic power due to adding RC's.
