Barrier Wall Systems

Noise Barrier Wall Systems for Outdoor and Industrial Noise Control

Barrier wall systems are an effective solution for reducing noise where full enclosure is not practical or required. Commercial Acoustics designs noise barrier walls using high-performance modular acoustical panels to block and reduce sound from outdoor and industrial noise sources.

These acoustic noise barriers are commonly specified to control sound from mechanical equipment, HVAC systems, generators, chillers, rooftop units, and other stationary noise sources that impact nearby occupants or property lines.

What Is a Noise Barrier Wall?

A noise barrier wall, sometimes referred to as a sound barrier for walls or noise control barrier, is a freestanding or attached structure designed to block the direct path of sound between a noise source and a receiver. By interrupting line-of-sight transmission, barrier wall systems reduce the amount of sound that reaches surrounding areas.

Unlike absorptive treatments, noise barrier walls rely on mass, height, and placement to achieve sound reduction and are often used in outdoor or large-scale industrial environments.

Applications for Sound Barrier Walls

Barrier wall systems are used in a wide range of commercial and industrial settings where noise must be reduced without enclosing the equipment.

Common applications include:

• Rooftop HVAC and mechanical equipment
• Generators and emergency power systems
• Chillers, compressors, and pumps
• Industrial exhaust and process equipment
• Utility yards and outdoor mechanical areas
• Commercial facilities near noise-sensitive properties

In these environments, sound barriers for walls help manage environmental noise while maintaining equipment accessibility and ventilation.

Engineered Barrier Wall Systems

Commercial Acoustics barrier wall systems are constructed using modular acoustical panels designed for outdoor performance and long-term durability.

Standard system features include:

• Modular panel construction for flexible height and length
• High-mass panels for effective sound blocking
• Configurable STC ratings based on project requirements
• Structural designs engineered for wind load resistance
• Durable materials and finishes suitable for outdoor exposure

Each noise control barrier is engineered to meet both acoustic and structural criteria, ensuring consistent performance across varying site conditions.

New Construction and Retrofit Solutions

Barrier wall systems can be integrated into new construction projects or installed as part of retrofit noise mitigation efforts. Modular designs allow systems to be adapted to tight footprints, irregular layouts, and existing equipment configurations.

Whether installed at grade or on rooftops, noise control barriers provide a practical approach to reducing sound impact without major facility disruption.

Proven Installations

Commercial Acoustics barrier wall systems have been deployed across diverse applications where environmental noise reduction is critical.

Example installations include:

Arizona Humane Society

Explorer Pipeline – Joplin, Missouri

In each case, acoustic noise barriers were designed to address site-specific noise challenges while meeting durability and performance expectations.
