AbstractThis project was a continuation of an earlier project 1,2 to determine the factors that are important in determining the degree of sound transmission through floors. Studies of fire resistance of floors carried out in this joint project are dealt with in other IRC internal reports. The report presents measurements of airborne and impact sound transmission through 67 floor assemblies?wood joists, wood trusses, wood Ijoists, and cold-formed C-shape steel joists. Three types of sound-absorbing material were used and two thicknesses of Type X gypsum board. The results of this phase of the project were combined with those from Phase I and used to refine a regression model for estimating sound transmission class, impact insulation class and some other single-number ratings. The regression model was used to create a small program for estimating these ratings for a restricted set of common floors.
