What’s That Noise? Gymnasiums
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.

I have looked at PVC baffles and will continue to research them. I have had someone mention to me a spray on material for the ceiling. Because of the sporting activities that may be something I would want to know more about. It’s effectiveness and cost and what types of surfaces it can be applied to.
