  1. What’s That Noise? Gymnasiums

    1 Comment

    In this ongoing blog series, the acoustic experts of ASI will detail common noise concerns of different environments and offer solutions to resolve any issues. This month’s edition of What’s That Noise? focuses on gymnasiums—wide-open spaces that are highly conducive to generating echoes and reverberation.

    Upon entering a gymnasium, the first thing that people notice—almost immediately—is the noise. At any given time, there are dozens of unwanted sounds fluctuating throughout these recreational facilities. Squeaking sneakers, booming voices and footsteps, and piercing music are only some of the sounds you’ll encounter regularly.

    Gymnasiums aren’t limited to just exercise and sporting events; these multi-purpose spaces often serve as venues for banquets, concerts, performances, and business conferences as well. Regardless of their specific purpose, all gymnasiums are constructed similarly; they are always composed of wood, painted concrete or cinder blocks, and metal roof decks—all of which are highly reflective surfaces.

    When you combine large gym spaces, reflective surfaces, and a lack of absorptive surfaces (e.g. carpet, furniture, drapery or ceiling tiles), this results in excessive echoes and reverberations. With little to no absorption in the room, sounds constantly bounce around until running out of energy.

    This noise problem is especially troublesome when gymnasiums are for conferences or instructional events; speech intelligibility in the room suffers greatly since people hear sounds that have been reflected several times. This delayed response causes a lot of confusion, as people have difficulty distinguishing one sounds from another.

    How Can I Resolve the Problem?

    To facilitate appropriate noise abatement, many gymnasiums are treated with hanging baffles or absorptive wall or ceiling panels. Baffles are ideal for this application, but it’s important to observe and take note of the fire suppression sprinklers; installing baffles in a location that’s inhibiting the coverage of the fire sprinklers is a huge safety concern.

    Acousitcal Surfaces, Inc. (ASI) has led the soundproofing industry for over 30 years. People frequently rely on our sound expertise to solve noise problems in various settings.

    In gymnasiums, our Echo Eliminator™ Acoustical Panels are a great resource for noise abatement for walls or ceilings. These panels are cost effective, lightweight, and easy to install. Our Echo Eliminator™ panels are sold in 2×4 panels and are available in 10 different colors in both 1” and 2” thickneses. In addition to possessing exceptional absorptive properties, these panels are also Class A fire rated to provide added security.  It is also important to know that these panels are generally in stock and because they do not need to be made/fabricated, we can generally ship an order in just a few days.

    ASI’s PVC Wrapped Acoustical Baffles are also a popular choice for gymnasiums (with high ceilings and no fire suppression systems). These high-performance baffles are composed of heat-sealed polyethylene (PVC) with a fiberglass fill, making them absorbent enough to cut down reverberations. Our baffles are available in sizes up to 4’x10’, as well as various colors to compliment the design of you gym.

  2. What’s That Noise? Office Environments

    This month’s edition of What’s That Noise? focuses on office environments—enclosed areas that depend on quietness to ensure the clearest communication possible.

    Millions of Americans spend 40 or more hours working in office buildings each week. Unfortunately, not all the time spent by office employees is productive, as the buildings they work in are a constant source of unsolicited noise.

    If you’ve worked in an office, or even briefly visited one, then you are well aware of the noises people encounter in these buildings—keyboard clicking, calls with clients or other employees, and loud music are a few prime examples. These individual noises are irritating and distracting, but they aren’t the biggest problem befalling offices today; sound transmission from room to room is the real culprit.

    Interestingly enough, the construction of office buildings is what promotes sound transmission. During construction, components like heating and cooling systems, water pipes, are run along the ceiling of a building. Next, walls are built and a “drop-ceiling” is installed to cover the surfaces. Finally, doors are installed and the rooms are finished. In each of these areas, very little attention is given to sound absorbing materials.

    People tend to assume that walls are the main source of sound transmission, but generally speaking, sound travels too fast (1,130 feet per second to be exact) to determine its precise location. Regardless of location, these sounds interfere with office productivity, and often cause confusion among employees.

    How Can I Resolve the Problem?

    It can be challenging, but the first step is to try and pinpoint the general problem area—your choice of noise abatement products will depend on the specifics of the room.

    For ceiling tiles, the Acoustical Surfaces team recommends two exceptional products: NOISE S.T.O.P.™ Sound Barrier ACT Tiles offer both high sound absorption (for echo and reverberation within a room) and are designed with a noise barrier on the back of the tile to help to block sound from entering or leaving an office; Barrier Decoupler  can be used on the back of STANDARD ceiling tiles to reduce sound transmission and contain intrusive noises.

    For office doorways, we recommend Door Seal Kits—these products are adjustable, durable, and are ideal for decreasing the amount of sound transmission through door seals. Our door seals are easy-to-install and available in several custom sizes.

    Finally, adding wall panels will help absorb echoes and reverberation throughout the office. Our NOISE S.T.O.P. FABRISORB™  fabric-wrapped fiberglass panels are custom engineered to provide high-performance noise reduction in any office area.  These panels can also be fabricated with a core of a dense, heavy vinyl that will offer the ability to block sound transmission as well.
