The Science of
Silence
How sound insulation, vibration damping, and acoustic absorption work together to deliver complete noise control.
The Three Challenges of Sound Control
Every acoustic environment faces three distinct problems. Each requires a different engineering solution and different materials.
Airborne Sound
Sound transmitted through the air — voices, music, bass frequencies. Requires high-density mass barriers to block energy from passing between spaces.
Key Metric
Up to 35 dB
Sound Reduction Index (Rw)
Structure-Borne Vibration
Vibrations travelling through walls, floors, and ceilings. Requires mechanical decoupling — isolating structures so vibration energy cannot transfer between elements.
Key Metric
Natural freq <5 Hz
Below audible range
Room Acoustics
Internal reflections creating echo and reverberation. Requires porous absorption materials that convert sound energy into heat, reducing reverb time and improving clarity.
Key Metric
NRC up to 0.95
Noise Reduction Coefficient
Mass-Spring-Mass Principle
Our core insulation technology relies on the Mass-Spring-Mass physical law. By sandwiching a viscoelastic EPDM damping layer (the spring) between high-density boards (the mass), we effectively decouple the structure and prevent sound transmission.
When sound waves hit the first mass layer, they cause vibration. As this energy travels through the EPDM damping core, it is converted into minute amounts of heat energy through shear deformation — significantly reducing the energy that reaches the second mass layer.
- Dissimilar Mass Layers
Different board materials prevent resonance coupling
- EPDM Damping Core
Viscoelastic rubber converts vibration to heat
- Energy-to-Heat Conversion
Sound energy is dissipated, not reflected or transmitted
"Every layer has a purpose. Every material is chosen for its acoustic contribution."

Vibration Isolation Principle
Structure-borne vibration is the most challenging acoustic problem. When bass frequencies cause walls, floors, and ceilings to vibrate, the entire building structure becomes a speaker — transmitting noise to every connected room.
Our damping products use mechanical decoupling — physically isolating one structural element from another using spring-loaded and viscoelastic components. This breaks the vibration path, achieving natural frequencies below 5 Hz — well below the audible range.
- Spring isolation for ceilings, walls, and floors
- Viscoelastic mats for surface-level damping
- Speaker pads to isolate subwoofer vibration

Porous Fibre Absorption
When sound enters a room, it bounces off hard surfaces creating echo and reverberation. Absorption panels solve this by converting reflected sound energy into heat through friction within a porous fibre network.
The Noise Reduction Coefficient (NRC) measures how effectively a material absorbs sound. An NRC of 1.0 means total absorption; 0.0 means total reflection. Our AcousPanel achieves NRC ratings of 0.70 to 0.95, making it highly effective across mid-to-high-frequency ranges.
- Reduces reverb time for speech intelligibility
- Improves musical clarity in performance spaces
- Higher NRC with rear air cavity (100mm–200mm)

The Final Seal
Even the best insulation system fails if gaps remain. Sound travels through the path of least resistance — a 1% gap in coverage can transmit up to 50% of sound energy. Acoustic sealant closes every joint, edge, and penetration point to ensure the system performs as designed.
SG-AS65 is a permanently flexible, non-hardening sealant rated at 32 dB. It maintains its seal through building movement and temperature changes, with an operating range of -40°C to 150°C.
