Silencor®

Metal Systems

Q: What is the difference between a metal enclosure and metal wall panels?

A metal enclosure system surrounds noisy equipment such as generators, compressors, or HVAC units for maximum noise containment. Metal wall panels create perimeter sound barrier walls or mechanical yard screens that block or absorb noise without fully enclosing the equipment.

Q: Do Silencor® Metal Systems comply with OSHA noise regulations?

Silencor® Metal Systems are designed to help facilities reduce workplace noise exposure and support OSHA noise control goals. Final compliance depends on site-specific measurements and overall facility noise conditions.

Q: What industries use Silencor® Metal Systems?

Silencor® Metal Systems are commonly used in power generation facilities, manufacturing plants, data centers, hospitals, healthcare facilities, water and wastewater treatment plants, and commercial mechanical yards.

ALL NOISE CONTROL

SILENCOR® METAL SYSTEMS

All Noise Control’s Silencor® Metal Systems include both Silencor® Metal Enclosures and Silencor® Metal Wall Panels, engineered to control industrial and mechanical equipment noise in indoor and outdoor environments. Built using double-walled acoustic panel assemblies available in multiple materials, thicknesses, and finishes, these systems provide reliable sound transmission loss and long-term durability.

Metal enclosures are commonly used to fully surround high-noise equipment such as generators, compressors, fans, and pumps, while metal wall panels are designed to create perimeter sound barriers or mechanical yard noise walls. Each system is engineered with proper ventilation, structural integrity, and maintenance access to ensure safe equipment operation while delivering effective industrial noise reduction.

Application

All Noise Control’s Silencor® Metal Systems utilize modular, double-walled acoustic panels with high-mass cores engineered to provide both sound absorption and transmission loss. Depending on configuration, systems typically achieve noise reductions of 20–35 dBA or greater. Designed for indoor and outdoor installations, these metal enclosure and wall panel systems are built to withstand weather exposure, wind and snow loading, and can be finished with durable powder-coated or corrosion-resistant materials.

Electrical Systems – Stainless-steel acoustic enclosures and wall systems feature solid outer shells with perforated inner liners to maximize transmission loss while allowing internal sound absorption and maintenance accessibility.

Power & Generators – Steel generator enclosure systems are engineered to address low-frequency noise, integrate proper ventilation and thermal management, and provide safe personnel access while maintaining regulatory compliance.

Industrial Equipment – Custom metal enclosures and acoustic wall panels for HVAC units, compressors, pumps, and mechanical yard equipment reduce airborne noise and vibration while preserving service access and airflow.

Outdoor Installations – Exterior-rated metal soundproof systems are designed for UV exposure, moisture protection, structural wind loads, and long-term acoustic performance in exposed industrial environments.
