Acoustic Hanging Baffles

Acoustic hanging baffles

are ideal for large spaces with trusses or beams. Hung overhead with chains, these baffles can absorb sound in even the largest industrial spaces or noisiest venues. Install them across a whole warehouse or gymnasium to dampen echo without obstructing vision or mobility. Or group them around noise sources like manufacturing equipment to help reduce the noise.

Installing free-hanging sound baffles

Sound Absorbing Hanging Baffles

are almost always suspended on chains from beams or girders. Where you choose to use them depends on how sound travels through the space. They’re most effective when placed close to the source of the noise. You can also use them to intercept noise before it hits hard surfaces that would cause the sound to echo.

Installation options

When hung perpendicular to the existing structure, free-hanging sound baffles are suspended between girders. A staggered pattern, like the one shown below, offers the most efficient way to break up sound waves.

Baffle Echo-Sound Reduction Layout
If we know the distance between the trusses (center on center dimensions) we can adjust the shiffener width on the top edge of the free hanging baffle to make sure the vertical chains are straight.

Other baffle hanging options

You can also install free-hanging baffles parallel to the girders so that both chains of the baffle attach to the same beam.
Free Hanging Noise Baffle
Create sound-absorbing corners by hanging baffles at a 90-degree angle or in a square formation above a noise source. This is especially helpful in the corners of a large room or when hung directly above noisy equipment. If possible, consider using hybrid baffles for even more noise absorption.

How many free-hanging baffles do I need?

The more soft surfaces you have, the more sound you can absorb. Acoustic baffles are filled with sound-absorbing material to interrupt the flow of sound waves and minimize echo.

Exactly how many you need depends on the space and the type of sound.

Low-frequency sounds, often caused by generators and manufacturing equipment, are the most difficult to absorb. You’ll need more baffles to get the job done. We also recommend the 4” thick absorption material for industrial settings. It gives you double the absorption material of the standard product.

If your budget doesn’t allow you to hang baffles from every beam, start with a few and then test the noise levels to measure the effect. With just two anchor points, free-hanging sound baffles are easy to install wherever you need them.

The objective is to prevent the sound to hit hard surfaces to give the sound soft materials to absorb in to.
