Perforated Acoustic Sandwich Panel (1).png

Perforated Acoustic Sandwich Panel

By modifying the core material composition and density gradient, this product effectively mitigate impact-induced noise generated on metal surfaces. Simultaneously, embedded damping fiber mats within the core layer suppress resonance-borne noise through viscoelastic energy dissipation. The engineered synergy between systematically perforated steel facings and stratified sound-absorbing media enables frequency-specific acoustic performance. This composite architecture achieves tunable sound absorption coefficients (αw 0.70-0.95) across target frequency bands.

Key Features

1. Engineered Noise Control System

Through customizing core materials (like rock wool or fiberglass), it showed synergy with the precision-perforated facings to block noise transmission in real usage. Laboratory tests proved that it could help to achieve ≥29dB noise reduction across multiple frequency bands.

2. Dual Sound-Absorption Mechanism

- Surface Noise Dissipation: Micro-perforations could diffuse sound wave energy, and help in reducing impact noise on metal surfaces.

- Core Vibration Damping: High-density acoustic cores suppress the structural resonance and disrupt sound paths.

3. Custom Acoustic Solutions

Configurable parameters for targeted frequency control:

① Core material density (60-150kg/m³)

② Perforation pattern & open area ratio (8%-24%)

③ Panel thickness (50-200mm could be customized)

Applications

Perforated acoustic sandwich panels are extensively used in:

1. Architectural Systems: Interior/exterior partition walls, curtain wall backing, composite wall cladding, acoustic ceilings

2. Industrial Equipment: Electrical cabinets, transformer enclosures, compressor rooms, high-speed punch press noise control

3. Critical Facilities: HVAC plant rooms, boiler houses, cooling towers, pump stations, power generator insulation

4. Public Infrastructure: Airport terminals, convention centers, railway sound barriers, highway noise walls

5. Acoustic Spaces: Broadcasting studios, cinemas, concert halls, multi-function auditoriums, classrooms
