THX and Quiet Solution Announce THX Certified Soundproofing

by Dhiram Shah

THX Ltd and Quiet Solution, LLC, has announced the availability of the first THX Certified soundproofing wall and ceiling panels, QuietRock™ QR-545. By meeting the THX specifications for sound isolation and achieving the coveted THX certification, the QR-545 promises to deliver the professional installer/dealer community with the ultimate sound isolation solution for demanding home theater and studio designs. Drawing from more than 20 years of experience designing and certifying cinemas, professional post-production studios and CE products, THX engineers found that the QR-545 is one of the industry’s highest performing sound isolation solutions, as measured by Sound Transmission Class (STC) standards.


Quiet Solution manufactures the THX Certified QR-545 panels using the company’s patent-pending CPG (Ceramic-Polymer-Gypsum) composite technology. In addition to being tested by technicians at THX, the 1-3/8″ panels were tested by globally recognized labs at the National Research Council of Canada (NRC), which showed the industry’s highest ratings, approaching STC 80, for QuietRock QR-545. This level of acoustic isolation performance is unprecedented, exceeding other techniques by 20 decibels or more. Low frequency performance exceeds 50dB in the highest-rated assemblies. This performance is achieved in a drywall-like panel that hangs and finishes just like standard drywall.
The patent-pending CPG composite technology in QuietRock QR-545 uses advanced viscoelastic polymers, ceramics and gypsum in a constrained 11-layer fabrication. The standard size 4′ x 8′ panels are manufactured by Quiet Solution at its Silicon Valley factory and will be available from more than 250 CEDIA and building material dealers nationwide beginning in October.
