Acoustic material and product testing
Traceable — not in accredited scope
Specifiers and buyers ask for numbers: NRC, αw, STC, Rw, IIC, Lw. We produce those numbers from physical specimens in physical rooms, and report them with the method, the mounting condition and the uncertainty attached.

Which standard should you ask for?
It is decided by whoever will read your report, not by the laboratory. European and most Asian specifiers work in ISO and want Rw and αw; North American specifiers work in ASTM and want STC and NRC. Tell us the destination market and we will tell you which test to book — and if you sell into both, we will tell you honestly whether one test can serve both.
