Advanced Structural Noise Control Systems
True soundproofing requires a strategic combination of mass, damping, and decoupling. Relying on lightweight absorption materials alone cannot stop standard low-frequency sound waves or structural impact vibrations.
QinSound’s high-performance sound insulation matrix provides premium STC (Sound Transmission Class) rated barriers. Our systems are designed to systematically upgrade standard partitions, floors, and industrial enclosures into absolute acoustic safe-havens.
Acoustic Law of Mass
To double the sound transmission loss, you must theoretically quadruple the weight of the partition, or introduce advanced viscoelastic damping. Our three material families allow you to achieve supreme STC upgrades with minimal thickness footprint.
The 3 Pillars of High-Performance Soundproofing
Vibration Damping Materials
Engineered viscoelastic materials designed to eliminate structural impact noise, resonance, and low-frequency mechanical rattle. By converting vibrational kinetic energy into trace thermal energy, these dampeners are critical for treating mechanical equipment, HVAC metal ductwork, and structural building floating floors.
- Best For: Pump Rooms, Generator Enclosures, Floating Gym Floors, HVAC Ductwork.
- Key Specs: High Loss Factor | Severe Structural Shock Absorption | Ageing & Corrosion Resistant.
Sound Insulation Felt
A high-density, ultra-flexible mass-loaded polymeric compound engineered to add immense structural mass within minimal thickness. Perfect for layering between standard gypsum boards or steel plates to disrupt the coincidence effect and maximize airborne sound transmission loss (STC).
- Best For: Commercial Partition Walls, Multi-family Residential Walls, Pipes Wrap, Ceiling Plenums.
- Key Specs: High Surface Density (2kg/m² – 5kg/m²) | Only 1.2mm – 3mm Thickness | Flexible & Tear-Resistant.
Sound Insulation Cotton
A porous, high-density matrix of engineered fine fibers (such as pure eco-polyester or high-grade mineral glass wool) tailored to fit inside wall cavities. It dampens internal cavity resonance, fully eliminating the “drum effect” inside drywall studs to maximize the partition’s overall acoustic isolation performance.
- Best For: Interstitial Stud Cavities, Dropped Ceiling Plenums, Recording Studio Basements.
- Key Specs: Optimal Tortuosity & Fiber Density | Flame-Retardant | Non-Irritating & Zero Odor.
