C – MUTE SYSTEM 63 is a thin point connected soundproofing system for ceilings developed and refined over the years by the R&D department of DECIBEL. C – MUTE is a product designed to reduce the impact and airborne noise in residential and public premises.

The main acoustical principle used in the system is mass + spring + mass as in the electromechanical analogy. DECIBEL engineers have created an extra thin and 4 times more effective system, mounted via 8 specially designed anti-vibration DClox fastening elements.

What allows DECIBEL to ensures the quality and efficiency of the system is that its soundproofing parameters are simulated using FEM and after that verified with laboratory tests.

DClox is a patented fastener specially designed for the installation of C – MUTE SYSTEM soundproofing panels.

The innovative fasteners are made from special elastomers, making them an effective vibro insulation point connection between the existing partition wall and the panel. Their geometry reduces the rate of sound transmission and minimizes the contacting area between the soundproofing panels and the existing wall to below 1%.

DClant – Sound and vibro insulating sealant, which adds +3 dB to the system

DCvisco – Sound and vibro insulating membrane, which adds +3 dB to the system

Dimensions C – MUTE 63: 1000 x 1200 x 63 mm

Weight C – MUTE 63 panel: 19.2 kg

Panel-wall contacting area: less than 1 %

Airborne sound reduction C – MUTE 33 (used with concrete ceiling slab 15 cm, Dslab = 2240 kg/m3): to 71 dB

Impact sound reduction C – MUTE 33 (used with concrete ceiling slab 15 cm, Dslab = 2240 kg/m3):  to 51 dB
