Industrial Noise Control:

Supporting Employee Safety and Productivity

The right combination of acoustic baffles can cover acoustically reflective surfaces and dampen the sound around noise sources to create a safer and more productive work environment. Proper echo reduction can help your facility meet OSHA standards of acceptable noise levels and protect employee health. Your employees will be able to work longer and safe.

Industrial Use - Acoustic Baffles

More than 30 million workers experience dangerously high levels of noise in the workplace and hearing loss is one of the most reported work injuries in the United States. To protect workers, OSHA is enhancing its enforcement of industrial noise control standards.

Installing acoustic baffles can help you protect employee health, improve productivity, and avoid costly fines and penalties.


Acoustic baffles offer noise control for all industries, including:

Manufacturing

Auto Body

Food Processing

Aviation

Pharmaceuticals

Sports/Recreation

Retail

Farm/Agricultural

Architectural Noise Control: Improving the visitor experience

The many hard surfaces of an industrial facility or other large venue reflect sound. The result is echo and reverberation. With so much ambient noise, visitors may struggle to hear a speaker or even hold a conversation.

A combination of free-hanging, ceiling, corner, and wall baffles can provide architectural noise control and even add to the aesthetics of the space. With a variety of colors to choose from, you can select acoustic baffles that fade into the background or stand out as part of the decor. Whichever noise control solution you choose, your visitors will enjoy the improved sound quality AmCraft baffles offer. The more you add, the more acoustic energy you can absorb. That leads to an improved visitor experience and better events.

Our sales team of acoustic baffle experts can help you find the solution for your noisy space.

Excessive noise is a common hindrance to productivity.

To shield employees, it is important to absorb sound that may become not only a productivity issue, but also a health issue (headaches, tinnitus, high blood pressure, anxiety, etc.). More than 30 million workers experience dangerous high levels of noise in the workplace; hearing loss is one of the top reported work injuries in the United States.

Ceiling Mounted Acoustic Baffles

When considering sound baffle and/or acoustic banners, any sound reflecting surfaces are a good place to start. Please note lighting and fire suppression system outlet locations within your facility when considering your industrial acoustics project. Your local fire authority is the best source of guidelines for ceiling-mounted baffles / acoustic banners when a fire suppression system exists. Depending on your ceiling type, you can employ horizontal, vertical, or a soft wave type sound energy panel system. Both ceiling and wall-mounted acoustic baffle panels are exceptionally effective with mid to high frequency noise containment situations and are best handled with some combination of partition sound blockage and panel or cloud type sound absorbency.

When people need to stay in an area with a high noise level, reasonable efforts and expense can render significant noise level reduction. Since effective sound-absorbing materials are typically soft and not highly abrasion-resistant, the placement of acoustic baffle systems is vital to its effectiveness for echo reduction.

What are reverberations (reverb)?

Reverberation (reverb) happens when sound reflects off of a hard surface, prolonging the noise. Drywall, glass, tile, architectural peaks, domes, and other concave surfaces reflect sound long after the initial energy is generated, resulting in echoes.

In the short term, echoes can make it difficult to hear what’s going on in the room. Over the long term, high levels of noise can damage hearing and even contribute to hearing loss.

Intense, or high-decibel, sounds can discomfort people, whether they are workers in a manufacturing facility or an audience at a sporting event. AmCraft sound baffles help absorb reverberation for a more comfortable work and entertainment environment.

Evaluate Sound Baffles: noise reduction coefficient

To choose the right combination of sound baffles for your space, consider the Noise Reduction Coefficient (NRC). The NRC standard is a numerical index that indicates the absorption qualities of a material based on four general sound frequencies (250, 500, 1000, and 2000 Hertz).

Acoustic baffles are categorized based on the NRC value, which indicates the level of sound that is absorbed. For example, a material that has an NRC of .90 absorbs 90% of the sound, while it reflects 10% back into the space.

So, can you actually expect a 90% noise reduction? No, you can not. It is a different NRC per frequency band. With a complex broadband noise, it isn’t so simple to say the product will absorb a certain percentage of the noise in the room. The absorption will be frequency dependent and also depend on the physical dimensions of the baffle, the room size and what kind of hard surfaces are in the room. If the baffle has a high NRC close to 1.0 that is ideal, but it will also have to be deployed in the right locations and amount of coverage for the room, to achieve the wanted measured ambient noise level.

AmCraft acoustic baffles have an acoustic chamber on the inside that can be customized to meet your echo reduction and noise dampening needs.

Low-frequency vs. High-Frequency sounds

Low-frequency sounds, between 100 Hz and 150 HZ, are generally more common in warehouse and industrial settings. Generators, mental punch presses, and pneumatic jackhammers all produce low-frequency sounds. The resulting sound waves are longer than high-frequency waves, making them audible at greater distances and more difficult to dampen. They create vibrations that can impact the structural integrity of a building as well as the physical safety and comfort of personnel.

You’ll need more acoustic treatment panels to dampen low-frequency sounds. This can be achieved with a mix of our sound baffles and acoustic curtains. Acoustic curtains don’t just absorb sound. They also give you the option to enclose the source of the noise.

AmCraft manufactures acoustic curtains, sound-absorbing wall panels, and acoustic baffles to reduce reverberations and sound reflection.

Where to Install Acoustic Baffles

When considering sound baffles, any hard surfaces are a good place to start since they’re most likely to reflect sound. Wall and corner baffles can help minimize echo in almost any space.

You can use hybrid baffles to divide wider spaces that have multiple work zones. Since they absorb sounds on both sides, they’re also useful to hang directly over the noise source. We can customize the width and height of hybrid baffles to fit your space even if there are obstructions. Tall spaces with metal ceilings or girders may benefit from ceiling baffles or free-hanging baffles that intercept sound before it hits these surfaces.

Please note lighting and fire suppression system outlet locations within your facility when planning acoustic baffle installation. Your local fire authority is the best source of guidelines for how to install sound baffles without disrupting fire suppression systems.

Noise Reduction Coefficient for Sound-Absorbing Systems

It is important to have a basic understanding of Noise Reduction Coefficient (NRC) when considering acoustic baffle systems for your work environment. The NRC standard is a numerical index that indicates the absorption qualities of material, based off of four general sound frequencies (250, 500, 1000, and 2000 Hertz). An NRC value will indicate the level of sound that is absorbed.

A material that has an NRC of .90 means that the material absorbs 90% of the sound, while it reflects 10% of the sound back into the space. AmCraft acoustic baffles have an acoustic chamber on the inside of the curtain wall that can be customized to your echo reduction (also known as reverberation reduction) and/or noise dampening needs. The acoustic chamber has a core that can include insulation rated for sound absorption.

Sound-Absorbing Baffles and Panel Systems

With a combination of AmCraft’s sound-absorbing wall panels, acoustic baffles, and acoustical curtains, the echoing and sound reflection can be reduced to a more comfortable level. Higher frequency sounds (i.e. woodworking machinery, stone cutters, ambulance sirens, etc.) are much easier to absorb than low frequency sounds (i.e. generators, printing presses, metal punch press operations, pneumatic jackhammer, etc.). Low frequency sounds are generally more common warehouse and/or industrial acoustics and are in between the range of 100 Hz – 150 Hz, whereas high frequency sounds have a higher “pitch” to them. Low frequency waves are much longer than high frequency waves, making low frequency waves more audible at greater distances and greater difficulty to reduce echo and noise. This creates a “vibration” effect that tampers with structural integrity of a building as well as the physical safety and comfort of personnel.

AmCraft manufactures the ideal acoustical curtains, sound-absorbing wall panels, and acoustic baffles that will help to reduce reverberations and sound reflection. For low frequency sounds, it is important to have more soundwave-absorbing “obstructions” in order to break down and interrupt the wavelengths. This can be achieved by having a mix of the sound baffles, wall panels, and acoustic curtains occur more often with high frequency noise situations.
