Quilted Fiberglass Absorbers Case Study – Noise Control

Somers Maximum Security Prison needed a room where a judge, witnesses and Inmates would gather for a trial at the facility. The room chosen, surrounded by glass, needed acoustical treatment. All Noise Control Quilted Fiberglass Absorbers were chosen to surround the top perimeter.

Quilted Fiberglass Absorbers are soft, porous, open celled materials that are used to reduce the reflection of sound waves. As a result, reverberation time and ambient noise levels are reduced thereby improving communication in the room.

Acoustical Ceiling Baffles were also suspended from the ceiling to help reduce reverberation problems in the room as well.

RE: INSTALLATION OF SOUND CHANNELS-2 ACOUSTICAL FABRIC

The attached installation instructions and guidelines should be thoroughly reviewed before installing this product.

The appearance of the finished installation will depend on several factors. A few that should be mentioned are whether or not the installation instructions were followed; the condition of the wall surface to which the fabric is applied; the type of adhesive that was used and the lighting in the room.

It is very important to follow the installation instructions closely in order to insure a satisfactory appearance of the finished wall.

We hope you find this information helpful. Best Regards,

MAINTENANCE AND CLEANING
Structured acoustical wall covering, made with face fibers of Polyester, will stay attractive and serviceable with regular vacuuming. Most spots and stains will disappear when treated with mild detergent or cleaning solvent.

MATERIAL
Carefully inspect all shipments. Check and examine material. We cannot be responsible for any imperfections after goods are cut. Before cutting, be sure the pattern and color and satisfactory. Purchaser assumes all responsibility for goods after cutting. No claims will be allowed for labor. All returns must have prior Return Authorization Number and are subject to a 25% restocking charge. All requests for returns must be made within thirty (30) days of ship date.

WALLS
Walls are to be structurally sound and free of dirt, grease, and markings. All markings which cannot easily be removed should be sealed so that ”bleeding” through the wall covering shall not occur. Although it is not necessary for the installation of wall carpet, sealed walls, especially on newly installed drywall, could facilitate future removal of wall covering and lessen damage to walls.

INSTALLATION
Cut material to desired lengths, allowing for top and bottom trimming. Apply a premixed heavy duty adhesive directly to the wall, allowing it to dry to its maximum stack ability without it being overly dry. (IMPORTANT!!! ADHESIVE IS READY MIXED AND SHOULD BE USED AS IT COMES OUT OF THE CAN. DO NOT MIX WITH WATER AND DO NOT PASTE THE BACK OF THE ALLCOVERING). This material is not factory trimmed. It is necessary for the paperhanger to cut a straight edge. All edges must be butt joined. WALLCARPET SHOU LD BE HUNG STRAIGHT UP…DO NOT
ALTERNATELY REVERSE STRIPS…Apply a second coat of undiluted adhesive to the wall, allowing it to dry to its maximum tack ability without it being overly dry. Be careful not to get adhesive onto the face of the wall covering, as it cannot readily be removed. Should adhesive get onto the face, it is best to allow it to dry and flake it off with a stiff brush. Do not attempt to wash affected areas, as this will only serve to dilute the adhesive and spread it over a wider area Install three strips and inspect all for color, uniformity, and correctness of application. If satisfactory, proceed with work as work proceeds, small areas (3 strips) should be inspected so that there are no more than 3 strips in question at any time. If anything goes wrong, STOP WORK IMMEDIATELY and contact your nearest representative for inspection. All seams shall be vertical and only full widths of material should be applied for the most satisfactory installation. Headers over doors may cause shading. All seams shall be at least 6 inches away from inside or outside comers.

Adhesive should have low water base and dry clear or translucent. Room temperature should remain stable at about 65 degrees F- 85 degrees F and be well ventilated before, during and up to 72 hours of the installation. High humidity will extend curing time and may cause Sound Channels to ruffle. Apply adhesive with a 1/16” v-notched trowel at a 45 degree angle. Allow adhesive to tack up before applying the Sound Channels. Rollout Sound Channels with a 1/4” roller. Trim edges with wall covering back cutter or under cutter to true pattern repeat. You may want to tack a few small nails or staples at the top of the fabric to prevent any sliding.

For best results, it is recommended that a qualified textile installer be employed.

Guide to Cleaning Sound Channels 2 Acoustical Fabrics

1brough installation procedures, or consumer use, fabric may become contaminated and require spot cleaning from time to time. The following information is provided as a guideline for the care and cleaning of acoustical fabric made from Polyester fibers. Because this material is made from synthetic fibers, it cleans very well with virtually no damage to the color or construction itself. Most commercially available Carpet and Upholstery cleaners will do an excellent job removing stains. From time to time, additional cleaning methods may need to be employed to remove stubborn or difficult stains.

General

Soundproofing

Soundproofing is any means of reducing the sound pressure with respect to a specified sound source and receptor. There are several basic approaches to reducing sound: increasing the distance between source and receiver, using noise barriers to block or absorb the energy of the sound waves, using damping structures such as sound baffles, or using active anti-noise sound generators.

Soundproofing affects sound in two different ways: noise reduction and noise absorption. Noise reduction simply blocks the passage of sound waves through the use of distance and intervening objects in the sound path.

Noise absorption operates by transforming the sound wave. Noise absorption involves suppressing echoes, reverberation, resonance and reflection. The damping characteristics of the materials it is made out of are important in noise absorption. The wetness or moisture level in a medium can also reflect sound waves, significantly reducing and distorting the sound traveling through it, making moisture an important factor in soundproofing.

Clarke School needed a resolution to noise polution……………

Challenges:
Clarke School contacted All Noise Control; they needed a resolution to a noise pollution. Clarke School needed suggestions on what to use for their project, they needed something that would prevent echoing within the room, also to prevent vibration noise troubles in large place as well with noise going out. Clarke found in 1867 in Northampton by Gardiner Green Hubbard, whose four-year-old daughter, Mabel, became deaf from scarlet fever. Firmly believing his daughter could speak and learn just like other children, Hubbard hired a teacher to work with Mabel on her speech and language. At age 10, Mabel did as well in the classroom as any of her hearing peers. Clarke provides children who are deaf and hard of hearing with the listening, learning, and spoken language skills they need to succeed. Annually, more than 800 children and their families benefit from programs and services at their five campus locations: Boston, Jacksonville, New York City, Northampton and Philadelphia.
