Small rooms often exhibit poor low frequency response with significant emphasis at modal resonances. They also have limited space to make acoustical improvements. Porous surface absorption is ineffective at these modal frequencies, because the air motion near walls and in corners is essentially zero for these long wavelengths. RPG® research solved this dilemma by developing a unique membrane system that converts the high sound pressure fluctuations typically found at wall surfaces and in corners into selective absorption in the modal frequency range. As the use of sub-woofers becomes more and more popular, there is a growing need for modal frequency management.

SpecifiedBy is now part of CausewayOne
We've updated our name and branding as the first step towards product data interoperability and the Golden Thread across the CausewayOne platform.
The features you rely on stay the same
For now, you can continue to use the www.specifiedby.com domain to access the same product data and search functionality.
Why the change?
CausewayOne is a construction operations platform used by 1,000's of contractors to design, win, manage and deliver projects.
CausewayOne Product Explorer will develop further to bring a central interoperable product data layer to all our contractor applications; by removing data siloes across parties & applications we can work towards a safer and more efficient industry.
