Oversized Curtain Enclosure

Building an oversized curtain enclosure to reduce and absorb noise has never been a problem. Building an oversized curtain system without a lot of support columns has always been a challenge...But we enjoy a good Challenge. Here's how we did it-

Application Introduction

Acoustical Solutions, Inc. designed a 2 1/2" x 2 1/2" x 3/16" thick heavy-duty steel frame that easily supports large enclosures was developed. A ten-foot square curtain enclosure only requires four corner posts instead of the usual support columns installed at five-foot intervals.

According to the shop's engineer, the product grinder was the most noise offensive piece of equipment in the company's entire operation. Noise levels exceeded 100 dB(A). Because the unit was relatively small (3' x 4' x 6'), we knew we could easily reduce the noise level with a curtain enclosure. However, the steel pieces moving in and out of the roll shop are so big that a full10' x 10' access area was required.

Treatment Provided

Acoustical Solution's heavy-duty frame system and AudioSeal™ Combination blankets solved the problem. Even at a height of 10 feet, the enclosure only required four corner posts and no middle post. Even large fork trucks have easy access and the pre-drilled and tapped frame made it quick to assemble and easy to install. The structure was rugged enough to accommodate a partial roof over the grinder. Because only a partial roof was used, there was no need to consider ventilation, lighting or sprinkler systems.

 

 

Quantitative Results

AudioSeal™ Combination Blankets feature a heavy duty, reinforced loaded vinyl noise barrier exterior and a two-inch thick quilted fiberglass sound absorption interior. The panels were installed on sliding double tracks on two sides for quick and easy access. The remaining two sides were attached directly to the frame thus saving the cost of track and rollers. The result? An overall noise reduction of 17 dB(A). In addition to significantly reducing noise levels, the curtains are durable enough to withstand the punishment we know they'll get in that busy area. Virtually any large area can now be enclosed without compromising access.

The next time you're confronted with a large, noisy piece of equipment that looks impossible to enclose with acoustical curtains, don't hesitate. Think heavy duty.

Product Questions & Comments (2 items)

  • If you are looking to reduce the noise level in an indoor gun range, you will need sound absorbing materials. The most common of these are acoustical wall panels because people tend to prefer the look they provide. However, for an application like this, durability should also be considered, which is why we would recommend acoustical blankets for the walls as an alternative. They absorb noise just like panels, but have a sturdy vinyl cover, which may be important if you have people/equipment bumping into them (or hot ammo casings). Our Sales Rep Aaron Duncan recently did an order for the indoor gun range at University of Virginia and acoustical blankets are what were installed in that case as well. Acoustical foam is a third option. Foam is absorptive as well, and inexpensive, but is not as sturdy and the look is not always preferred in commercial applications.

    Absorptive materials could also be applied to the ceilings, as well as walls. There are acoustical ceiling tiles and baffles available, but if you have low ceilings the baffles would probably not be practical in a gun range. These recommendations are for reducing noise WITHIN the firing room, if you are looking to soundproof the firing room (keeping noise from escaping into other areas of the business) then a different set of products would be appropriate.

    Please let us know if this is the case and feel free to contact us with any other questions you may have. Thank you.
