Acoustic Walls and Noise Barriers

Noise Control Solutions for Industrial and Commercial Applications

Description
Technical Data

Acoustic walls and noise barriers are free-standing industrial noise control structures designed to reduce noise transmission between noisy operating areas and noise-sensitive locations. Burgess-Manning acoustic plant screens and noise barriers are specified for applications where a full acoustic enclosure is impractical, including externally mounted plant equipment, mechanical plant areas and site boundary noise control.

Burgess-Manning acoustic walls are constructed using high-performance acoustic panels mounted to a series of vertical steel posts fixed to a concrete foundation. The modular design places no limitations on overall dimensions, allowing barriers to be configured to suit any site layout or project requirement.

Panels are available in multiple thicknesses from 50mm to 150mm (2 to 6 inches) depending on the noise reduction requirement of the project. The outer panel casing is manufactured from galvanized steel, stainless steel or aluminum, enclosing layers of sound-absorbing mineral wool. This construction reduces noise transmission while preventing rot, mold and bacterial growth. Panels are independently tested and can provide up to 50 dB of sound reduction. Acoustic walls are designed for hurricane and typhoon conditions up to 160 mph wind loading.

Construction options range from pre-assembled modular builds for rapid deployment to site-built panel screens with integrated support steelwork, providing flexibility for projects with access or site condition constraints. Panels can be pre-cut to reduce installation time and are suitable for worldwide transportation by container.

Modular Designs

The modular panel system places no limitations on overall wall dimensions, allowing acoustic barriers to be configured to suit any site layout. Panels can be pre-cut for faster installation and are easily transportable by container for international projects.

Engineered Durability

Panel outer casings are manufactured from galvanized steel, stainless steel or aluminum, enclosing sound-absorbing mineral wool. This construction reduces noise transmission while preventing rot, mold and bacterial growth in all operating environments.

Tested Performance

Acoustic panels are independently tested and the wall system is designed to withstand hurricane and typhoon wind loads up to 160 mph, providing confirmed performance in the most demanding site conditions.

Relevant Industries

Oil and gas refineries, natural gas processing plants and LNG facilities represent remarkably intensive and acoustically challenging industrial environments, generating intense noise levels from complex processing equipment, high-pressure systems and continuous operations. Hydrocarbon processing facilities require comprehensive noise control solutions to ensure worker safety, regulatory compliance, community relations and operational efficiency.

Industrial applications generate considerable noise as a result of high-capacity machinery, continuous operations and complex infrastructure. Without proper noise control, these environments can pose risks to employee health, disrupt surrounding communities and violate environmental and occupational noise regulations. Implementing tailored noise mitigation solutions of acoustic walls, noise barriers and silencers while utilizing acoustic modeling, CFD, FEA and noise measurements to design solutions not only supports safety, but also enhances operational efficiency and community relations.

Acoustic Walls/Noise Barrier FAQ

Noise barrier walls are supplied by industrial acoustics companies like Burgess-Manning specializing in outdoor noise control. These barriers are designed to reduce noise propagation toward nearby communities and sensitive areas.

Soundproofing panels for factories are supplied by noise control manufacturers like Burgess-Manning offering absorptive and barrier panel systems. These panels are commonly used for walls, ceilings and partial enclosures to reduce reflected and transmitted noise inside industrial buildings.

The terms are used interchangeably to describe the same product. An acoustic wall or noise barrier is a free-standing structure designed to reduce noise transmission between a noise source and a noise-sensitive location. Both terms refer to panel-based systems mounted to structural posts, as opposed to enclosures that fully surround a piece of equipment.

Acoustic walls reduce noise transmission by approximately 15 to 20 dB due to sound passing over the top of the barrier. The acoustic panels themselves are independently tested and can achieve up to 50 dB of sound reduction depending on panel thickness and configuration. The overall performance of an installed barrier depends on the height of the wall, the distance between the noise source and the receptor and the frequency spectrum of the source noise.

Acoustic walls are used across oil and gas, power generation and general industrial applications. Typical installations include site boundary noise barriers for industrial facilities, screens around externally mounted plant equipment such as air handling units, chillers and compressors and noise control barriers between operational areas and noise-sensitive locations such as neighboring properties or personnel areas.

Acoustic walls are designed as modular, free-standing structures fixed to concrete foundations. The modular panel system and pre-cut panel option allow for installation with minimal disruption to existing site operations. If a noise study is not already available, Burgess-Manning can provide the acoustic analysis required to determine the correct wall height, length and panel specification for the site.
