Excessive noise and vibration create significant challenges across multiple industries, affecting health, safety, and productivity.
85 dB+ = Hearing Damage Risk
Continuous exposure to industrial noise above 85 dB can cause permanent hearing loss, affecting worker safety and compliance with OSHA regulations.
Engine & Road Noise = Reduced Comfort
Vehicle noise pollution from engines, exhaust systems, and road contact reduces driving comfort and affects perceived vehicle quality and value.
Poor Sound Insulation = Privacy Issues
Inadequate acoustic treatment in buildings leads to sound transmission between rooms, affecting privacy, concentration, and overall building performance.
Our metal foam technology provides superior acoustic performance through its unique porous structure that dissipates sound energy and reduces vibration transmission.
Metal foam's interconnected porous structure creates multiple pathways for sound waves to travel, converting acoustic energy into heat through friction within the foam cells.
Compared to Traditional Materials:
Metal foam acoustic solutions are transforming noise control across multiple industries with proven performance in real-world applications.
Challenge: Reduce vehicle interior noise while maintaining thermal and structural performance.

Challenge: Improve sound insulation in buildings for privacy, comfort, and regulatory compliance.
Solution: Metal foam panels integrated into walls, ceilings, and floors.
Quantifiable performance metrics demonstrating the superior acoustic properties of metal foam materials.
Measures sound absorption performance (0 = no absorption, 1 = perfect absorption)
Measures airborne sound insulation (higher = better isolation)
Measure of vibration energy dissipation (higher = better damping)
Broad frequency coverage from low bass to high treble sounds
Significant weight reduction compared to traditional acoustic materials
Wide temperature performance unlike polymer-based acoustic materials
