- Abstract
- This is the second of two papers that consider the effect of resilient metal channels (RCs) on structure borne transmission from wood studs to gypsum board. Readers are referred to the first paper for wall details, definitions, and measurement procedures. This paper examines several simplifications that might be used when creating a model for structure borne transmission from a wood stud to gypsum board that is mounted on RCs. Possible simplifications include assuming transmission is reasonably independent of the location of the RCs, but is dependent on the number, and that the total power transmission is simply the sum of transmission through individual RCs. The paper concludes with the reduction in radiated sound power velocity that might be expected if direct attached gypsum board is mounted on RCs.
