Institutions / Gymnasiums & Multi-Purpose Rooms Soundproofing

In the heart if Texas, Milan middle school had a noise reverberation problem typical to institution spaces such as gyms, cafeterias, auditorium and general purpose rooms. We all associate the echoes, noise and reverberation of sound with gyms, pool areas & large auditorium / multipurpose rooms and certainly can relate to the high noise levels in these types of rooms. In this middle school gymnasium (a problem in virtual all gymnasiums), the sound bounces off the walls more than the basketballs. Do to the volume and space in these rooms and lack of noise absorbents, the noise grows and creates echoes and reverberation seriously impeding speech intelligibility. When the gym was in use, the conversation next to you was indistinguishable from the conversation across the floor. During sporting events, the noise became unbearable with the gym full of fans, parents and students. The noise levels at sporting events Is already an unhealthy exposure to high decibels especially with no acoustic noise control absorbents in place.

The school reached out to All Noise Control to help them solve their problem. One of All Noise Control’s core markets are Institutions be it middle school, college or other.  All Noise Control suggests their Ceiling Baffle products to help these types of institution noise problems due to their cost effectiveness and noise reduction qualities. Ceiling baffles are a great source of noise reduction in these types of applications benefiting a NRC rating of 1.25. A series of 2’ x 4’ x 1.5” thick ANC-600 acoustical ceiling baffles in between the ceiling trusses was suggested to Milan Middle School. The ANC-600 baffles are constructed of a high density fiberglass core to absorb maximum sound. In addition they have great fire ratings and fire retardant properties. By installing these baffles high in the ceiling, institutions like this Middle School benefit by avoiding most if not all contact between the acoustical baffles and mobile gym equipment such as basketballs, volleyballs, etc.

Once the ANC-600 ceiling baffles were installed the noise quieted down, speech became coherent and their problem was solved. Using the gym for future events was not only healthier for the ears of students and visitors alike, but it also made the use of the gymnasium much more enjoyable.

We invite you to call All Noise Control at 561-964-9360 to discuss the noise control materials supplied to this particular middle school and are just as happy to listen to your individual needs and supply you with a customized All Noise Control Solution.

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.

Soundproofing Case Study


The problem:

HHI Corporation contacted All Noise Control; they needed a resolution to a noise pollution that would prevent echoing within the room, also to prevent vibration noise troubles in large place as well with noise going out. The main objective of the project was to avert the echoing, and to prevent sound exposure noises within the project.

The Solution:

All Noise Control recommended the Acoustical Ceiling Baffles. This would eliminate built up sound due to noise reflection, in other words the echoing, and sound exposure. With the Acoustical Ceiling Baffle the noise would be dramatically reduce. This Acoustical Ceiling Baffle it is ideal for these applications.

Soundproofing and Noise Control Frequently Asked Questions

We have listed below some of the most common questions and their answers in hopes of providing basic knowledge related to noise, and noise control products and systems.

What is Noise?
Noise is defined as unwanted sound. Unwanted sound can be hazardous to your hearing or can be simply disturbing, interfering or annoying. Sound does not have to be loud to be unwanted.

What level does noise become harmful to me?
Driven by OSHA standards, corporate safety departments and insurance carriers, noise levels are typically set 85 dB-A as the high noise level. Individuals exposed to this noise are permitted to work an 8 hour shift with hearing protection. Administrative and engineered controls should be taken to reduce the employees noise exposure at 85 dB-A.

What is dB-A?
The sound pressure level designed to closely reflect the response of the human ear. We are less sensitive to low and high frequencies, thus an “A” weighted noise level is what we hear.

What does 85 dB-A sound like?
Buses, motorcycles, and pneumatic tools at 50 feet. You must raise you voice to a near shout to speak over 85 dB-A.

What is N.R.C.?
The Noise Reduction Coefficient of a product is the average absorption across four octave band center frequencies. (250 Hz., 500 Hz., 1000 Hz., 2000 Hz.) You can roughly estimate that a product with an NRC .75 will absorb 75% of the sound energy that hits it. The highest level is NRC 1.0.

What is STC?
A single number decibel rating of the transmission loss properties of a product. Doors, windows, walls, floors, etc. are tested to determine how much noise passes through. The testing determines a product’s STC. The higher the number the better.

How do we prevent equipment from overheating in a noise enclosure?
Silenced ventilation systems can be as simple as a blower system that moves existing plant air through the enclosure or as complex as separate HVAC systems. Silencers on the intake and exhaust will prevent the passage of noise in or out of the enclosure.

How do we maintain access to the equipment for maintenance?
Maintenance access is a key consideration in the design of an enclosure. Lengthy discussions with the equipment operators and maintenance personnel will ensure proper access is provided to all required areas. Swing, sliding, and removable doors and plugs are how most access is obtained.

Why is the machinery louder in my shop than what the manufacturer’s data shows?
Most equipment is tested in a free field condition, a room with no hard surfaces that reflect sound. Most industrial facilities have hard floor, hard walls, and hard ceilings. The reflected sound can build up to create a higher noise level. When the equipment is placed near other machinery making noise you can build noise as well. Isolating each piece of equipment can dramatically reduce the noise levels.

Why do I care about noise at my property line?
Noise is measured at your lot line. The neighbor’s home may be 400 feet from the lot line but codes state that you cannot send noise off your property. Communities may or may not have a noise ordinance for you to follow. If they do not have an existing ordinance you can be assured they will write one directed at you.
