Acoustic Enclosures
Acoustic enclosures (also referred to as noise or sound enclosures) are a key design element in bringing industrial, process, and manufacturing facilities to safer noise levels for a healthier, more productive work environment.
Designed to isolate the noise source or protect the people impacted by it, a properly engineered acoustic enclosure will account for operator and maintenance access, ventilation, safety codes, air quality, egress, and future expansion needs. At O’Neill Engineered Systems, our IAC Acoustics modular noise enclosures can be custom-designed for many noise control applications.
What are acoustic enclosures?
Acoustic enclosures consist of pre-engineered, modular acoustical metal panels that are configured and assembled into a wide variety of structures designed to isolate, reduce, and control excessive noise levels. These systems are used across industrial, commercial, institutional, and community environments.
Our modular acoustic panels are uniquely suited for applications requiring a high degree of noise reduction – 25 decibels (dB) or more – combined with rugged, long-lasting durability. A complete modular acoustic enclosure system can be customized to include:
- Integration of lighting, ventilation, fire protection systems, air-conditioning, etc.
- Advanced sound- and vibration-isolating floor systems
- Designs for interior and exterior installation sites
- High-performance sound control door and window systems
- Installation services
Key Features of Sound Enclosures
Our sound dampening enclosures are constructed using market-leading components engineered to meet exact acoustic, aerodynamic, and structural requirements.
- Walls, ceilings, and floors
- Moisture Protection – Integrated protection for internal absorption materials prevents the entrapment of volatile or corrosive liquids.
- Noise-Foil System – Advanced sound absorption system reduces reverberant noise build-up within existing “hard” structures.
- Fire-Noise-Lock Construction – Optional configurations offer a certified 1.5-hour fire rating, with all components shipped with a UL label.
- Sound control doors and accessories
- Personnel Doors – Single- and double-leaf “Cam-Lift,” no-sill doors offering clear openings up to 8’ x 14’ (2,438 x 4,267 mm). Custom designs for larger opening are available.
- UL Fire-Rated Doors – 3-hour certified ratings available up to 42” x 90” (single-leaf, 1,067 x 2,286 mm) and 84” x 90” (double-leaf, 2,134 x 2,286 mm) clear openings.
- Acoustic Windows – Double-glazed window units that provide maximum visibility with zero loss of acoustic integrity.
- Safety Hardware – Built-in panic hardware and access plugs for rapid local access.
- Captive Hardware – Removable panel details engineered with fully captive hardware for simple maintenance access.
- Premium materials
- Standard Materials – Built with cold-rolled solid steel and galvanized steel, treated with a durable powder-coated finish.
- Optional Materials – Full galvanized construction or specialized stainless steel builds (contact IAC Acoustics for details).
- Blast Resistance – Moduline structures and components can be precision-engineered to withstand intense blast loads, ensuring doors remain fully operable after a blast event.
- Integrated ventilation systems
- Acoustically Compatible Systems – Airflow capacities range from 100 to 10,000 cfm (170 to 17,000 m³/hr).
- High-Performance Silencers – A wide selection of acoustically and aerodynamically rated silencers tailored to meet normal and highly exacting facility requirements.
What Are the Benefits of Noise Enclosures?
Implementing high-performance acoustic enclosures into your facility provides critical operational, safety, and regulatory advantages.
- Improved Workplace Safety – Lowers ambient decibel levels to comply with OSHA regulations, mitigating the risk of workplace hearing loss.
- Enhanced Productivity – Reduces acoustic fatigue and communication disruptions, allowing operators to work more efficiently and comfortably.
- Environmental Compliance – Helps industrial facilities meet strict community and municipal noise ordinances at property boundaries.
- Durable Longevity – Built using powder-coated metals that resist wear and tear in harsh industrial environments.
- Flexible Engineering – Modular design allows for seamless disassembly, relocation, or future configuration expansions.
