For those wracked with guilt that their acoustic treatment is a burden for the planet — petroleum product, exotic hardwood, et al — Auralex rides to the rescue with Sustain Bamboo Sound Diffusors.
Made from fast-growing and easily replaced bamboo, the Sustain series is available in many standard acoustic treatment product configurations: pyramids, slats and those checkerboard designs that look like curio holders when mounted on a wall.
Also available are KeyPac perforated panels for mounting with Auralex ProPanels or Studiofoam. KeyPacs can temper the amount of sound absorption a room has.
And if you’re still having unexplained guilt pangs with Sustain Bamboo, rest easier since Auralex points out that the bamboo used for its products isn’t the same as that pandas eat.
