    GO GREEN with Audimute sound absorbing drapery material

    Not only do Audimute Sound Absorption Sheets offer outstanding acoustic performance, but they are also manufactured from recycled cotton natural fibers, reducing landfill waste. Audimute's inexpensive sound absorbtion material is safe and non-toxic.

    So why choose man-made fiberglass, dubbed as the next asbestos by many? Exposure to airborne fiberglass particles or direct contact with the product can cause skin, eye, nose and throat irritation and itching. Coughing is also a reaction to inhaled fibers. What’s more, fiberglass is considered to be a probable carcinogen by National Institutes of Health.  Fiberglass product packages display cancer warning labels unlike Audimute's cotton inexpensive sound absorbtion material that do not require this warning. These labels are required by the U.S. Occupational Safety and Health Administration (OSHA) based on determinations made by the International Agency for Research on Cancer (IARC) and the National Toxicology Program (NTP).

    Be good to yourself and your environment, choose Audimute Sound Absorption Sheets, the natural and safe acoustic solution, a better alternative to fiberglass.

    How much absorption material is necessary for an effective room acoustics treatment? It’s a fair question to ask before starting a sound improvement project. Though there’s no one-size-fits-all answer, we can offer some guidelines and considerations for obtaining the right sound.

    The right amount of absorption for a room acoustics treatment depends on four main and related variables:

    •   intended use of the room and the sound source;
    •   room size, including ceiling height;
    •   materials in the room, including furnishings and wall, floor, and ceiling type; and
    •   the type of absorption used.

    Start by defining success: Does the room sound need to be only lightly corrected, or does the room construction or purpose demand serious sound deadening?

    As a general rule, a moderate percentage of “live” (untreated) space is preferred—without it, a room sounds flat and lifeless. Use the following wall coverage percentages as a starting point for your room acoustics treatment (assuming absorption products rated .65 to 1.0 NRC - Noise Reduction Coefficient):

    •   Light absorption (5 to 25 percent coverage)—is appropriate for live recording or listening rooms, offices, conference rooms and rooms where people gather and converse.
    •   Moderate absorption (25 to 50 percent coverage)—suits listening and control rooms that typically feature more subdued music, as well as larger business spaces. Moderate absorption of around 50 percent is a good estimate for many home theaters.
    •   Heavy absorption (50 to 100 percent coverage)—suits drum rooms, music practice space, rooms that handle high-energy music. Vocal booths and recording isolation booths require the most absorption.

    It’s impossible to give a precise percentage without analyzing each unique space.  The amount of absorption necessary as a room acoustics treatment will vary significantly based on size, furnishings, and construction materials, so consider those elements carefully. For example, a larger room may require more absorptive material, carpeted floors and soft furnishings absorb sound and therefore will decrease the amount of additional absorption material needed, and paneled walls or large amounts of glass may significantly increase the necessary treatment.

    We offer a free and personalized room analysis form that you can use to submit information about your space, and one of our acoustics specialists will review your information and contact you with advice tailored to your specific needs. If your application is for a particularly large space or is a commercial application, use our large/commercial room analysis form.

    Also bear in mind that some sound absorbers have a higher noise reduction coefficient (NRC) than others, and the right amount depends on the level of absorption required, the aesthetic needs of the space, and the budget. Audimute offers three distinct absorption products to meet any need: sheets, wall coverings, and panels. Panels, our most decorative and effective option, rate a 1.0 NRC, while the less-expensive wall coverings rate a still impressive .75 NRC and sheets rate .65NRC. 

    There’s a lot to consider when deciding on a room acoustics treatment, so don’t go it alone.

    Dude...the sound is awesome. You can pick out every instrument. The whole band is excited....more pics soon. You can "tailor" a space for a big band with just audimute and a few architectural details !!!! Thanks!

    These sheets are amazing. Not only they blocked the sound coming out of our rehearsal room, but they also improved the sound quality inside the rehearsal room. My band is very happy with the results, we now can hear eachother!!!

    The sound absorption sheets perform exactly as described in your videos. I doubled or triple layered were I could. Myself (along with my wife, my neighbors) and are very happy with this product. I used the Zoom H4N digital recorder to record drums in my studio. The sound (due to the absorption sheets)was beyond compare to anything I recorded in that room prior. The drum sound was deep, full, wet, and you could hear every little sound articulation from every percussion piece on my kit. I was a liitle bummed that my order took a little longer to ship due to an error with Paypal. It was clear my payment had gone through but apparently Paypal didn't send the funds to your company until days later. No worries....I fully intend to purchase items from you again - you guys rock!!

    VERY!!!!!!!!!!! I was using them in a F.R.O.G. (Finished Room Over Garage) where I do some recording of my original songs and some others for my work. The difference was obvious on play back of the first recording I did with them. I was blown away with the clarity. I did a rough recording that would have sounded amateurish and muddy before. Now I have beautiful clarity of the parts...on JUST a rough recording. I could have used a number of other products, but the sheets provide me the quality of sound absorption as well as versatility of applications. Quite simply, I will not part with them!

    I've got this stuff and it's awesome. It's cuts down on the reverb in here big time and I found that it REALLY tightens up the bottom end of my monitors by draping them over the back of each speaker. They might not be the prettiest way to cut down on reverb but they're the most economical solution that doesn't involve nasty fiberglass.

    A few months ago, I rescued a juvenile sun conure. As the bird grew older, her calls kept getting louder and more high pitched to the point where it became impossible to stay in the same room with her. More importantly, the amount of noise to the outside was becoming embarrassingly loud and affecting my roommate's day to day life, even though our rooms is separated by a spacey living room. After doing some online research, I came across the Audimute Soundproofing website and I realized the absorption sheets might be exactly what I was looking for. I bought a package of 4 absorption sheets; one went up on my room's door, one on each wall at the corner where the cage is placed (to prevent the walls from reflecting and transmitting vibrations), and one around the back of the cage. When she starts screaming, all I need to do is turn the cage around to create a confined space surrounded by the Audimute material, and I instantly got all the noise control I could wish for! This extremely simple set up cut down on at least 60% of the noise within the room and took out most, if not all, of the high frequency waves that used to make my ears ring. I can easily sit at the computer desk by the cage now without being annoyed by the noise. More amazingly, the noise to the outside of my room was cut down by a hefty 80%, and close to 100% to my roommate's bedroom! She can no longer tell if the bird is awake or asleep from her bedroom anymore! Thank you Audimute for allowing me to bring back everybody's quality of life without having to re-home my pet!!! - Hans

    I am a rehearsal studio owner and musician. I found your product on the Internet while searching for sound proofing materials. You have a great site and very good products and you're from my home town area of Cleveland! Pros: Audimute sheets are a simple but effective design that work! Easy to install and move if necessary. A great and affordable alternative to foam products and better for the environment.

    Absorption Sheets & isole™ Installation Instructions:


    This is a high performance sound absorption product.  As such, it works best when in the same enclosed space where sound is being generated.

    • Ensure the product is completely exposed as the primary surface within the space and not covered with any dense/ hard surface material.
    • Do not cut Audimute sound absorption sheets to fit specific size requirements.  Fold the product instead.
    • Avoid penetrating with curtain hooks, nails, etc. as this will permanently damage the sheet(s).
    • For best results:  Allow the product to hang freely with a slight drape (curve).   Avoid stretching product flat against the wall surface.  The billowing effect will make for better sound absorption especially when 2" – 3" away from a wall.  
    • Position product on opposite walls if possible.   Don't be afraid to experiment with the product's position within in a room for varying acoustical effect.  Dry Clean or spot clean only.
    • Sheet Rock (Dry Wall) Hanging:  Use nails, screws, or screw on nobs (available through Audimute)
    • Wood Walls/ Mounting Boards:  Use same as dry wall method OR Industrial Staples.  Stapling is more permanent.

    Sheets with Grommets may be hung using our Quick Hanging Knobs. To install the knobs:

    1. Attach the knob by hand twisting it onto the flat end of the threaded bolt (included)

    2. Place the plastic anchor (included) in the installation surface if needed (recommended when hanging in dry wall, wall board, or similar wall/ceiling surfaces), pre-drilling a .25 inch pilot hole.

    3. Screw the  pointed end of the threaded bolt into the anchor or installation surface.

    4. Grasp the bolt lightly with pliers (recommended to hold the bolt in place the first time) and loosen the knob by twisting counter-clockwise.

    How do I know how much sound this product will absorb?

    NRC ratings are one of the best ways to compare similar sound absorption products and determine which are most effective in absorbing sound at various frequencies.  The higher the NRC rating, the more effective the product.

    How are NRC ratings determined?

    Only products that have been tested in a controlled lab setting receive an NRC rating.  The process of determining a product's NRC involves testing its performance across some of the most common frequencies, then averaging the sum of these individual ratings to determine the product's overall NRC.  In general, an NRC of 0 means a product is perfectly reflective, whereas an NRC of 1 means the product is perfectly absorptive. 

    Another way to look at these ratings is as a percentage.  For example, if a product has an overall NRC of .65 (such as Audimute Absorption Sheets), the product is estimated to absorb up to 65% of the mid and high frequencies in a room.   

    NRC Depends on Proper Use & Installation

    It's important to remember that the NRC of sound absorption products is determined based on proper use and installation.  If a product has not been installed following our recommended installation method, it may not be as effective. 

    In general, sound absorption products achieve poor NRC ratings in the low frequency ranges, but do extremely well absorbing mid and high frequencies.  Based on these results, we typically recommend absorption products for mid and high frequency applications, such as those dealing with noise from pianos, flutes, voices, etc. 

    Please feel free to give us a call at 866-505-MUTE if you have any questions regarding the installation requirements of a specific Audimute product.
