Our AlphaEnviro® PVC Sound Baffle is an economical hanging sound absorbing baffle with a wipe-able surface. Suspended vertically, these acoustical baffles are used to reduce and lower excessive reverberation times (RT60) in large open spaces. The baffles work to interrupt the path of the noise and reduce sound reverberation. Available in an array of bold colors, they can be manufactured in custom sizes up to 4′ x 10′.

Easily install these baffles using simple hardware through the grommets provided on the top width edge. You can suspend these baffles from ceilings, bar joists, cable, per-engineered truss systems and arranged in a manner to create dynamic looks or avoid lighting and HVAC equipment.

  7. Verified Customer

    The baffles work great to reduce the echo and sound in our dog kennel.

  8. Verified Customer

    Used these in the ceiling of our church gym to help knock out reverb from the ceiling. Easy to install and effective.

  9. Verified Customer

    We use the waterproof baffles in our indoor canine pool facility, in Rockville, VA. The baffles absorb the echo made by a dog barking. Their are so many hard surfaces in the pool area, such as the cinder block walls, glass windows,the ceiling, and finally the water from the pools. Without the well constructed baffles that drape down from the ceiling in rows, It would be uncomfortably loud. The baffles allow me to instruct my lessons with confidence the dog and handlers can hear me clearly.
