Client: Quiet Solution
Specimen: Wall assembly with QR-530
Specimen ID: B3433-6W
Construction Dates: September 18-19th, 2005
Test Specimen:
The wall had a single row of steel studs; on the exterior face of both sides was
QuietRock QR-530 panels. The 38 x 89 mm steel studs were spaced 610 mm on
center. The 89 mm thick, R12 glass fibre batts were installed in the cavities of the
single row of steel studs. The joints of the 13 mm thick QuietRock QR-530 panels
were caulked with QuietSeal acoustical sound sealant then covered with a metal tape.
The QuietRock QR-530 panels were attached vertically to the steel studs with 41mm
long, type S drywall screws spaced 406mm along the edges and in the field. The joints
of the QuietRock QR-530 panels on the two sides of the wall were offset by 400 mm.

Facility and Equipment: The acoustics test facility comprises two reverberation rooms (referred to in
this report as the small and large rooms)with a moveable test frame between the two rooms. In each
room, a calibrated Bruel & Kjaer type 4166 condenser microphone with preamp is moved under computer
control to nine positions, and measurements are made in both rooms using a real time analyzer controlled
by a desktop PC-type computer. Each room has four loudspeakers driven by separate amplifiers and
noise sources controlled by the computer. To increase the randomness of the sound field, there are also
fixed diffusing panels in each room.
Test Procedure:Airborne sound transmission measurements were conducted in accordance with the
requirements of ASTM E90-04, "Standard Method for Laboratory Measurement of Airborne Sound
Transmission Loss of Building Partitions". Airborne sound transmission loss tests were performed in the
forward (receiving room is the large room) and reverse (receiving room is the small room) directions.
Results presented in this report are the average of the tests in these two directions. In each case, sound
transmission loss values were calculated from the average sound pressure levels of both the source and
receiving rooms and the average reverberation times of the receiving room. One-third octave band
sound pressure levels were measured for 32 seconds at nine microphone positions in each room and
then averaged to get the average sound pressure level in each room. Five sound decays were averaged
to get the reverberation time at each microphone position in the receiving room; these times were
averaged to get the average reverberation times for the room. Information on the flanking limit of the
facility and reference specimen test results are available on request.
Significance of Test Results: ASTM E90-04 requires measurements in 1/3-octave bands in the
frequency range 100 Hz to 5000 Hz. Within those ranges, reproducibility has been assessed by inter-
laboratory round robin studies. The standards recommend making measurements and reporting results
over a larger frequency range, and this report presents such results, which may be useful for expert
evaluation of the specimen performance. The precision of results outside the 100 to 5000 Hz range has
not been established, but is expected to depend on laboratory-specific factors.
Sound Transmission Class (STC): was determined in accordance with ASTM E413-04, "Classification
for Rating Sound Insulation". The Sound Transmission Class (STC) is a single-figure rating scheme
intended to rate the acoustical performance of a partition element separating offices or dwellings. The
higher the value of the rating, the better the performance. The rating is intended to correlate with
subjective impressions of the sound insulation provided against the sounds of speech, radio, television,
music, and similar sources of noise characteristic of offices and dwellings. The STC is of limited use in
applications involving noise spectra that differ markedly from those referred to above (for example, heavy
machinery, power transformers, aircraft noise, motor vehicle noise). Generally, in such applications it is
preferable to consider the source levels and insulation requirements for each frequency band.
Confidence Limits: Acoustical measurement in rooms is a sampling process and as such has
associated with it a degree of uncertainty. By using enough microphone and loudspeaker positions, the
uncertainty can be reduced and upper and lower limits assigned to the probable error in the
measurement. These limits are called 95% confidence limits. They are calculated for each test according
to the procedures in ASTM E90-04 and must be less than upper limits given in the standards. These
confidence limits do not relate directly to the variation expected when a nominally identical specimen is
built, installed and tested (repeatability). Nor do they relate directly to the differences expected when
nominally identical specimens are tested in different laboratories (reproducibility).
In Situ Performance: Ratings obtained by this standard method tend to represent an upper limit to what
might be measured in a field test, due to structure-borne transmission ("flanking") and construction
deficiencies in actual buildings.
