Equipment noise barriers are modular acoustic enclosures designed to reduce industrial equipment noise transmission to surrounding areas. The 2.5m height is specifically engineered for typical industrial equipment — providing sufficient barrier height to block direct sound paths from generators, compressors, pumps, and HVAC units.
## Acoustic Design
The barrier panel is a composite sound-absorbing structure:
- **Outer Skin**: 0.8mm perforated galvanized steel (sound-transparent facing)
- **Core**: 50mm mineral wool insulation (80 kg/m3 density)
- **Inner Skin**: 0.6mm solid galvanized steel (sound-reflective backing)
- **Frame**: 1.5mm galvanized steel edge channel
- **Acoustic Performance**: NRC 0.85 (absorbs 85% of incident sound), STC 32 (reduces 32dB through panel)
## How It Works
1. **Sound Wave Approaches**: Equipment noise radiates outward as spherical waves
2. **Perforated Face**: Outer perforated skin allows sound waves to enter the panel
3. **Mineral Wool Absorption**: Sound energy converted to heat by friction in mineral wool fibers
4. **Solid Backing**: Inner solid skin prevents residual sound transmission through panel
5. **Barrier Shadow**: Tấm creates acoustic shadow zone behind barrier — typically 10-15dB reduction at receiver position
## Key Advantages
- **High Absorption**: NRC 0.85 — absorbs 85% of sound hitting panel surface. Prevents reverberant buildup.
- **Weatherproof**: Mạ Kẽm steel + moisture-resistant mineral wool. Suitable for outdoor equipment.
- **Modular**: Standard panel 2.0m x 0.5m. Connect to form any length and height.
- **Self-Supporting**: Tấms slide into steel posts — no additional framing needed.
- **Fire Resistant**: Mineral wool core is non-combustible (A1 fire rating). Meets building codes.
- **Maintenance Free**: Mạ Kẽm steel surface. No painting required for 15+ years.
