Test OL 11 1110, Figure 1 Insulated steel stud frame viewed from receiving room side. The single source room side sheeting layer consisted of two 5 8 thick 4 by 8. sheets of QuietRock ES EZ SNAP noise reducing drywall The QuietRock. ES sheets were fastened parallel to the steel stud frame with 1 1 4 long type. S12 drywall screws spaced at 12 on center The single layer was comprised. of two complete 4 by 8 sheets Figure 2 is a photograph of the source side.

Project Sound Transmission Loss Testing 8, Client Serious Energy Inc of 9 Orfield Laboratories Inc. Test OL 11 1110, The single receiving room side sheeting layer consisted of two 5 8 thick 4 by.
8 sheets of type X gypsum panels The type X gypsum sheets were fastened. parallel to the steel stud frame with 1 1 4 long type S12 drywall screws. spaced at 12 on center On the receiving room side the sheeting was. comprised of three sections to provide seams that were staggered from those. on the source side Figure 3 is a photograph of the receiving room side. Figure 3 Receiving room side sheeting installed and sealed in the specimen. Panels were shimmed at installation so equal gaps were at the top and bottom. Gaps were less than 1 4 in all cases Shims were removed after sheeting was. fastened and the vertical seams were sealed on the source and receiving room. sides with QuietSeal Pro acoustical sealant and 1 7 8 wide 5 mil aluminum foil. tape The perimeter of both sides of the sample were sealed with QuietSeal. Pro acoustical sealant 5 mil aluminum foil tape and 7 8 dense putty tape. NVLAP Lab Code 200248 0,T E S T R E P O R T,Project Sound Transmission Loss Testing 9.

Note The calculations in ISO 717 1 are performed based on assumed. equivalency of the ASTM and the corresponding ISO test methods The test. herein is performed according to the ASTM standards Orfield Laboratories. does not hold accreditation for ISO 140 or ISO 717 under their NVLAP scope of. accreditation, The spectrum adaptation terms C and Ctr characterize performance against two.
specific sound sources A weighted pink noise and A weighted traffic noise. respectively The standard ISO 717 1 includes a discussion of Use of. Spectrum Adaptation Terms in Annex A informative, Each spectrum adaptation term may additionally be reported with extended. frequency bands included A calculation for the primary frequency range is. shown above but all available extended frequency calculations were. performed to compare against corresponding ratings of other specimens.
