Construction Noise Control

Noise control enclosures that help meet workplace
noise regulations and improve safety.

SOUNDPROOF METAL ENCLOSURES

All Noise Control’s Metal Enclosures are custom-engineered using double-walled acoustic panel assemblies available in various materials, thicknesses, and finishes, making them ideal for both indoor and outdoor noise-control applications. These metal enclosures are commonly used around manufacturing equipment, generators, fans, pumps, and other high-noise machinery, delivering strong noise reduction through a combination of sound absorption and transmission-loss blocking. Each enclosure is designed with proper ventilation, maintenance access, and personnel entry to ensure equipment operates safely, efficiently, and without overheating.

Outdoor metal enclosures deliver long-term durability with UV/moisture protection, wind and snow loading

Applications

All Noise Control’s metal noise-control enclosures use modular, double-walled acoustic panels with a high-mass septum to deliver strong sound absorption and transmission loss, achieving typical noise reductions of 20–35 dBA. Built for indoor and outdoor use, they provide durable weather protection, wind and snow loading, and optional powder-coat finishes.

  • Electrical Systems – Stainless-steel enclosures with an outer solid shell and inner perforated shell offer high transmission loss, weather resistance, and easy maintenance access.
  • Power & Generators – Steel generator enclosures provide low-frequency noise reduction, proper ventilation, thermal control, and safe personnel access.
  • Industrial Equipment – Custom metal enclosures for HVAC units, compressors, and pumps use modular acoustic panels for enhanced sound absorption, vibration control, and simplified servicing.
  • Outdoor Use – Outdoor metal enclosures deliver long-term durability with UV/moisture protection, wind and snow loading, and consistent acoustic performance for exposed installations.

Custom Steel Enclosures with Advanced Performance Features

All Noise Control’s acoustic steel wall panels are designed with modular, double-walled panel construction to deliver outstanding sound absorption, transmission loss, and acoustic performance. Our steel enclosures also support advanced protection options like RFI/EMI shielding, X-ray shielding, and ballistic impact resistance for demanding applications.


We offer a complete line of ventilation packages, including forced ventilation, silenced inlet panels, plenums, and acoustic louver doors, engineered for proper system airflow and noise control. On the electrical side, All Noise Control provides access doors, personnel access, and a full range of electrical accessories—such as power outlets, switches, lighting, and load/distribution centers—designed for integration with high-STC modular enclosure systems.

Structural Integrity

All Noise Control’s acoustical steel soundproofing wall panels are engineered as self-supporting structures using modular, double-wall panel construction that meets standard building code requirements. For projects that require increased load-bearing capacity—such as outdoor installations exposed to wind and snow loading, seismic applications, or large spans and complex geometry—we can design a fully integrated structural support system tailored to the enclosure’s performance needs.

Acoustic Test Data for Metal Enclosures

All Noise Control provides independently certified acoustic test data from accredited laboratories, detailing the sound absorption and transmission loss characteristics of each panel type. These verified results ensure consistent high performance across all our metal enclosures, including stainless steel enclosures, acoustical steel wall panels, and steel generator enclosures.
