SECTION B – APPROACH
INSTALLATIONThe specimen is a wall assembly that was originally constructed on August 29, 2023, at the Saint Paul, MN acoustic laboratory facility. Theassembly and building element descriptions can be found in Section C on pages 4 & 5 of this report. Some details of the specimen design
are proprietary and have been withheld at the request of the test sponsor.
Qualified representatives from North Orbit Acoustic Laboratories observed or performed the installation and inspected all major building
elements when completed and prior to testing.

TEST METHODS
North Orbit Acoustic Laboratory (NOAL) is accredited through A2LA certificate number 4240.01 for this test method.
Test methods follow the published standards listed below.
ASTM E90-09 (2016): Standard Test Method for Laboratory Measurement of Airborne Sound Transmission Loss of Building Partitionsand Elements
ASTM E413-22: Classification for Rating Sound Insulation
All results reported herein were derived from tests performed in full accordance with test method ASTM E90. The laboratory andmeasurement systems fully meet all requirements of the test standard and the requirements of ASTM E90 Annex A2: Qualification of roomsound fields and microphone systems used for sampling. All values stated are derived from single-direction transmission loss
measurements.
The standard deviation of reproducibility is stated in ASTM E90 as <2 dB for frequencies from 125 Hz to 4 kHz. Detailed test procedures forthis test method, the flanking limit report, repeatability measurements and reference specimen tests are available upon request.
The Sound Transmission Class (STC) value was obtained by applying the Transmission Loss (TL) values to the STC reference contour of
ASTM E413 which was used to calculate a single number rating.

TEST REPORTS
This report does not constitute certification of the assembly or test item nor an opinion or endorsement by this laboratory. The reportapplies only to the specimen tested and may not be reproduced, except in full, without the permission of the client or test sponsor. It is theexclusive property of the test sponsor so named herein.

CONFIDENTIALITY
The test sponsor has full control over this information. Any release of information will be only to the test sponsor. The specific testing results
are deemed to be confidential exclusively for the test sponsor’s use. Reproduction of this report, except in full, is prohibited.

SECTION C – SPECIMEN DESCRIPTION
Hyperstud® steel studs, Hypertrack® steel tracks, and gypsum panels were supplied by the test sponsor. All other materials werepurchased through regional retail or wholesale channels.

FRAMING
Framing was constructed on August 29, 2023, and was retained for subsequent tests in the series.
A steel stud frame was constructed within the perimeter of the laboratory test specimen opening. The frame consisted of Hypertrack®
30 mil designated thickness 3-5/8" x 1-1/2" steel bottom track, Hypertrack® 30 mil designated thickness 3-5/8" x 3-1/4" steel top track,and ten Hyperstud® 18 mil designated thickness 3-5/8" x 1-1/4" steel studs installed vertically 16" on centers (OC). The studs wereengaged to the tracks with integral snap connectors. The perimeter of the frame was sealed at the specimen opening with non-hardening
acoustic sealant.

INSULATION
Glass fiber insulation batts were friction fit into the stud cavities. The batts were 16" wide and 3-1/2" thick with an R-Value of R-13.

RESILIENT CHANNELS
Single-leg resilient channels were fastened to the source side of the framing. The channels consisted of five 22 mil designation thickness,
2-1/2" wide x 1/2" deep, with 1-1/2" screw flange, and were installed horizontally, perpendicular to the studs, spaced 24" OC. The top andbottom channels were installed 4" from the top and bottom of the framing. Channels were fastened to the frame with #7 x 7/16" type S
screws at intersections.

SHEATHING
Source Side: One layer of 5/8" gypsum panels was applied parallel to the studs (perpendicular to the channels). The panels were attachedto the channels with #6 x 1" type S drywall screws spaced 12" OC.
Receiving Side: One layer of 5/8" Type X gypsum panels was applied parallel to the studs. The panels were attached to the frame with
#6 x 1" type S drywall screws spaced 12" OC. Joints were staggered one stud cavity on opposite sides.
All fasteners in the assembly installation were mechanically installed.
The panels were shimmed at installation so equal gaps were maintained at the top and bottom. Gaps were less than 3/8" in all cases. Shims
were removed after the panels were fastened and the perimeter and seams were sealed on the source and receiving room sides with nonhardening acoustical sealant. In addition, the perimeter of both sides of the specimen was sealed with 2" wide polypropylene tape and7/8" dense putty tape.

All materials were weighed prior to installation. The nominal dimensions and product information were provided by the test sponsor or
obtained from manufacturer data sheets. Mass of Hyperstud® and Hypertrack® includes mass of integral connectors, therefore linear
density includes those the average mass of those connectors along the lengths.

Note: Composite 95% confidence intervals from room qualification testing. Extended frequency results below 80Hz and above 5000Hz arefor reference only. Specimen TL rounded to 0.1 dB provided in this table for reference. Specimen TL rounded to whole decibels foundon page 2.
Data Flags:* Actual transmission loss of specimen may be higher than measured at this frequency band. Signal-to-noise in the receiving room lessthan 5 dB, therefore the result is "an estimate of the lower limit".
