Acoustica’s QuietWave® noise barrier isolates noise and dampens sound vibration increasing the sound transmission loss.
Noise transmission between light-weight construction partition wall systems has always been a challenge to control, often making it difficult to find an effective solution to integrate into the building design.
There is now a simple, efficient and cost-effective solution to this problem…it’s called QuietWave®
Independent laboratory tests have been performed to show the Airborne Sound Transmission results for various wall systems using the unique QuietWave® flexible visco-elastic membrane that consists of a patented constrained layer membrane, combined with vibration damping material ‘floating’ elements.
The QuietWave® wall system provides a saving of 50% in the width of the wall against a comparable 6 star rated wall system. Gain an extra 1m2 of floor-space for every 6.6m length of wall, effectively reducing the overall footprint of the acoustic partition wall.
Below is an extract from the test by PKA Acoustic Consulting conducted at the Rintoul acoustic development laboratory in 2006 using the following description of the sample wall construction;
70mm single steel stud frame with 50mm 14kg/m3 Glasswool as cavity infill. The frame was clad each side with 13mm 8.5 kg/m2 CSR CD plasterboard screw fixed and sealed with CSR pre-mixed all-purpose compound.
1mm 2.5 kg/m2 Acoustica QuietWave was stapled to the face of the plasterboard each side, completely covering the plasterboard. Another layer of 13mm 8.5 kg/m2 CSR CD plasterboard was screw fixed to each side and sealed with CSR pre-mixed all-purpose compound.

Further tests have been completed on double and staggered stud wall constructions. Results show the performance is even greater than the example above.
Acoustica’s QuietWave® wall system provides the best acoustic performance with the thinnest possible wall section.
