DECIBEL Block System™ - High-Performance Wall Soundproofing

DECIBEL Block System™ is a high-performance wall soundproofing solution designed for residential, public, and industrial projects. Built from multiple layers of insulating and absorbing materials, it delivers some of the highest levels of airborne noise reduction available. By combining certified acoustic components with a structurally separated design, it transforms ordinary walls into highly effective sound barriers.

How It Works

The system is mounted onto the parent wall using vibration-isolating mounts, which create a physical break that limits sound transmission. Within this frame, multiple layers of materials with different densities and elasticities are combined with specialised sound-absorbing infills. This engineered layering interrupts and dissipates sound energy before it can pass through the structure.

Thanks to its modular design, the Block System can be applied to both solid walls and lightweight partitions such as plasterboard stud walls, providing adaptable performance across project types.
