Whisperwave Clouds at UVA OpenGrounds

UVA OpenGroundsThe OpenGrounds facility at the University of Virginia was designed as a collaborative meeting and workspace for faculty and student groups. William Sherman, the architect behind the renovation of the building knew that a space with high ceilings and an open layout like this one, needed to have acoustics taken into consideration.

Large gatherings, open table discussions, and presentations require a room with low reverberation for speech intelligibility. So to achieve this, Sherman contacted us and we recommended Whisperwave™ Clouds. Whisperwave acoustical clouds are made with sound absorbing foam material with an NRC .85 and are effective at reducing high reverberation times created by bare surfaces.

Lindsey Hepler, the program manager for OpenGrounds, says that there was a noticeable difference in the sound and usability of the space after the Whisperwave Clouds were installed.

Quick Solutions: Soundproofing an Interior Window

Many business don’t own, but rent, their office space. This can cause a headache when modification of the facility is needed to suit the organization’s changing needs, but isn’t allowed by the landlord.

This was the case with a clinical social worker who rented a small office space in a great location. There was originally a receptionist’s office with an interior window connected to the waiting room. This office needed to be converted to a patient counseling room to accommodate the growing number of clients, but obviously the room had to be as private as possible. The transition would be impossible without completely soundproofing the opening in the wall - ideally by filling it in and making the whole wall solid.

The owner of the building wasn’t open to any permanent modifications, so the social worker called Acoustical Solutions to see if anything could be done to block sound completely through the opening.

ASI Rep Kevin McIver came up with the idea to use a combination sound blocking and absorbing product on the opening, that could be covered to hide the modification and put clients more at ease:

“We used an ABSC-25 blanket to cover the window on one side and they put up artwork on the either side”

The blanket has an STC of up to 33, the same sound transmission class as a standard interior wall. The response from the client was positive, and the installation method used suited their need for a removable solution:

“Hi Kevin . . . worked out great! Perfect fit and the heavy duty velcro helped to hold it securely to the outer molding!

Here is a pic of the blanket up and the outside of the window for you to get an idea of what it looks like underneath the blanket.

Thanks so much . . . I have given your card to a colleague of mine too! – Renee”

Acoustical Wall Panels and Ceiling Clouds for The Spirit of the Mountain Band at Liberty University

The Liberty University Band was upgrading and moving to a new rehearsal room when they called Acoustical Solutions.

Together, the two came up with a plan to install acoustic panels and hanging acoustic ceiling tiles to compliment the sound diffusion that had already been planned.

In the end, the noise control solutions that were put into place greatly improved the band room acoustics in the new facility. Read More

Soundproofing a Computer Lab: NCSU’s Acoustical Solution

North Carolina State University’s lab and office space in the engineering department had very low speech intelligibility making it difficult to hold conferences and classes. The problem was a long RT60, or reverberation time. Soundproofing against this noise issue requires sound absorbing materials like acoustical wall panels.

PolySorpt™ Sound Panels were installed along the walls to absorb sound energy, lowering the reflection of sound and therefore reducing the echo.






From the client: “I have the panels up and they look and sound great” 

PolySorpt are non-fibrous sound absorbing panels that can be used both indoors or outdoors to reduce ambient noise levels and excessive reverberation.

The panels can be glued directly to any wall or ceiling, or bolted down as pictured in this appication. These acoustical panels are offered in a standard flat surface pattern or a more decorative designer pattern you can see here.

PolySorpt comes in either charcoal gray or white, in 2′x2′ or 2′x4′, and 1 and 2 inch thicknesses. The 2″ version is NRC.70 and the 1″ is NRC.45.

Win Primacoustic Scatter Blocks for Your Music Room!

Our first giveaway of the year to celebrate our 25th Anniversary will be a set of Primacoustic Scatter Blocks!anniversary-seal2

Primacoustic Scatter Blocks are an easy-to-install acoustical treatment used in spaces where you want to control sound, but do not want to eliminate the natural room ambiance.

Scatter Blocks are an excellent choice for live-end, dead-end designs such as sound studios, media rooms, practice spaces, and home theaters. This acoustical treatment is designed to be randomly spaced on large wall surfaces to create an effect we call “soft diffusion”—an affordable alternative to full scale quadratic diffusion. By leaving reflective spaces between the panels, some sound energy is absorbed while the remainder is reflected back into the room. This helps control flutter echo and reduces standing waves while retaining a sense of liveliness and space in the room. 

If your music practice or recording room needs improved acoustics, you need to enter to win!

Simply go to our facebook page and comment on this image by telling us your favorite genre of music!



A winner will be chosen at random after one week, and will be notified through Facebook.

Good luck!

Reduce Outdoor Noise with a Sound Blocking Fence

As it gets warmer and people emerge from their winter hibernation into the summer sun, noise always becomes an issue. This is especially true when it comes to backyard noise in residential neighborhoods.

The source of the noise can be cookouts, pool pumps, air conditioning units, young children, or number of other things.

Regardless of whether you’re the one making the noise or the one trying to enjoy some quiet time one yard over, we recommend a sound blocking fence.  Also referred to as a soundproof fence, these sound barriers absorb noise and can also block it from transferring between properties.

Specifically, our most commonly used acoustical solution, and the most affordable product for residential sound blocking fences is our AudioSeal™ Exterior-Grade Acoustical Blankets.  These products are sold by the individual blanket or roll in standard sizes, making retrofits to existing structures easy and cost-effective.

Case Studies:
This particular person lived near Philadelphia and installed central air conditioning. Their neighbors complained to the city about the noise levels (notice how close the houses are) and she was told she couldn’t use her AC until she got the noise levels below the city ordinance. After discussions she decided to install a stockade fence and line it with AQFA-10 EXT sound absorbing blankets. She expedited the order since it was the week before memorial day. After installation of the AQFA-10 EXT material, the AC noise was well under the city ordinance noise limits. She stayed cool and comfortable all summer long!

The next story involves a bank next to a church. The bank installed a new AC system and it was too loud for the church. They weren’t required by law to do anything about the noise, but the business wanted to be a good neighbor. They installed ABBC-13 EXT blankets in the 2″ thick version (this model comes in 1″ or 2″ thicknesses, with an option for 2lb psf instead of 1lb for the 2″) on the side of the bank building and reduced the noise level to an acceptable level for the church..  Even though these panels aren’t supported by a fence, the acoustical treatment is just as effective. During the summer the church was able to open the windows without hearing a constant hum from the bank’s AC unit.

Both of these stories happen to be specifically about outdoor HVAC noise blocking, but this solution would work for any kind of outdoor noise. If the barrier will block the line of sight between you and noise source, it will block the sound as well.

The model AQFA-10EXT blanket is purely sound absorbing and consists of an exterior grade vinyl coated polyester on both sides of 2″ quilted fiberglass. These sound blankets are constructed with all edges bound and grommets across the top for easy hanging.

Features and Benefits:

  • STC 19 Rating, NRC .85*
  • Standard Width 48”
  • Roll Length 25’

The ABBC-13EXT blanket is both sound absorbing and blocking, which makes it something we call a “combination blanket”. It consists of a vinyl-coated-polyester-cloth facing encapsulating a 1″ quilted fiberglass that is bonded to a reinforced 1-lb per square foot mass loaded vinyl barrier.  These sound attenuation blankets are constructed with environmentally sustainable fiberglass filling with grommets across the top and Velcro® along the vertical edges of the blankets.

Features and Benefits:

  • STC 30-38 Rating, NRC .65 – .75*
  • Standard Width 54”
  • Roll Length 25’
  • Available Facing Colors Grey, Black,
    Tan or Olive Drab
