Frequently Asked Questions

A noise control enclosure is similar to a "box" (5 sides including roof; or 6 sides if a floor is to be included) incorporating an engineered system of acoustic panels with interlocking tongue and groove seams to achieve noise reduction (and absorption) specifications by isolating the noise source. Silencers and other noise control elements may be integrated into the enclosure design.

An acoustic barrier wall is an engineered sound absorptive panel system that is placed between the noise source and receiver for noise reduction purposes. These systems can be installed indoors or outdoors, vertically or horizontally, at grade or on rooftops, to meet noise requirements.

Complying with government regulations usually determines how loud something can be. These regulations often stipulate what level of noise a worker can be exposed to without proper hearing protection, or what noise level is permitted at the perimeter of your property, for example. Typically, most companies strive to meet 85 dBA within the workplace.

Our construction materials include: galvanized construction, pre-painted steel, stainless steel and aluminum.

• Typically have much higher mass and density which is important as this prevents sound from passing through the panel.
• Superior longevity - made for the extremes of outdoor conditions.
• Optimized (and customizable) widths and lengths - longer and wider panels require fewer panels per installation, saving time and labor costs. (Vinyl panels typically come in a fixed size only)
• 100% recyclable, environmental friendly and non-combustible.
• Will not become brittle with time/low temperatures and will never crack. Factory zinc basecoat ensures a lifetime of durability.
• Can be recoated (repainted) in the field, if desired.
• Have a proven environmental track record.
• Can be used as versatile building blocks for many indoor/outdoor environmental applications including extreme heat, exhaust and gases.
• Have very good structural rigidity.

We design and construct a wide range of noise reduction solutions, including noise control enclosures, acoustic barrier walls and acoustic panels. We offer a maximum panel length of 24ft. (the longest in the industry) which allows for faster installation and reduces the number of structural steel supports and fasteners required and further refines appearance and quality. Our construction materials include: galvanized construction, pre-painted steel, stainless steel and aluminum.

We offer most industrial wet-paint systems and powder coating (limits based on size and weight).

Yes, we provide ground shipping to anywhere in North America and containerized ship transportation to the rest of the world. However, if you require a different shipping method, we can almost always accommodate you.

On small orders, complete turnaround time for a custom-designed unit is less than four weeks, often two to three. For larger custom-designed orders, six to eight weeks is typical.

We do on-site installations anywhere in North America.

Absolutely! Especially if there is a critical noise reduction requirements, dB Noise Reduction will review and/or test equipment to verify it is operating properly and can guarantee performance.

Our standard warranty covers any defects or imperfections in design, materials, fabrication or performance during normal operation for a period of 18 months after shipment or 12 months after installation, whichever comes first.
