Acoustical Performance Test Report PAC INTERNATIONAL, LLC 6585 Whispering Sands Drive Las Vegas, Nevada 89131 Report No E4748.02-113-11 Test Date 01/30/15 Report Date 03/18/15 Project Scope Architectural Testing, Inc., a subsidiary of Intertek (Intertek-ATI), was contracted to conduct a sound transmission loss test. The complete test data is included as Appendix B of this report. The client provided the test specimen. Test Methods Testing for this project was conducted in accordance with the following standards. The equipment listed in the attachments meets the requirements of the following standards. ASTM E90-09, Standard Test Method for Laboratory Measurement of Airborne Sound Transmission Loss of Building Partitions and Elements ASTM E413-10, Classification for Rating Sound Insulation ASTM E1332-10a, Standard Classification for Rating Outdoor-Indoor Sound Attenuation ASTM E2235-04 (2012), Standard Test Method for Determination of Decay Rates for Use in Sound Insulation Test Methods Test Procedure All measurements were conducted in the HT test chambers at Intertek-ATI located in York, Pennsylvania. The sensitivity of the microphones was checked before measurements were conducted. The transmission loss values were obtained for a single direction of measurement. Two background noise sound pressure level and twenty-five sound absorption measurements were conducted at each of five microphone positions. Four sound pressure levels were made simultaneously in the receive and source rooms at each of five microphone positions. The air temperature and relative humidity conditions were monitored and recorded during all measurements. 130 Derry Court York, PA 17406 www.archtest.com www.intertek.com/building p. 717.764.7700 f. 717.764.4129

Page 2 of 5 Specimen Installation The specimen was constructed in a 168" wide by 120" high by 12" deep steel frame test opening. Dense neoprene foam (3/8" thick by 3" wide) was adhered to the steel frame perimeter. Top and bottom tracks were placed over the foam and fastened to the steel frame by TEK screws (3" long) with isolation washers. Test Calculations Transmission loss (TL) at each 1/3 octave frequency is the average source room sound pressure level minus the average receive room sound pressure level, plus 10 times the log of the specimen area divided by the sound absorption of the receive room with the sample in place. STC Rating To obtain the Sound Transmission Class (STC), read the TL of the contour curve at 500 Hz. The sum of the deficiencies below the contour curve may not exceed 32. The maximum deficiency at any one frequency may not exceed 8. OITC Rating The Outdoor-Indoor Transmission Class (OITC) is calculated by subtracting the logarithmic summation of the TL values from the logarithmic summation of the A-weighted transportation noise spectrum stated in ASTM E1332.
