Acoustishell™ Curvilinear Diffuser-Reflector


AcoustiShell™ Curvilinear Diffuser-Reflectors are constructed of FRP composites, are extremely rigid for low resonance and are more durable than gypsum products. Internal dampening is standard on all FRP AcoustiShell™ with AVL’s exclusive GeoMatrix core, which prevents unwanted ringing and resonances that color sound and tone. Different shapes and curvatures are available to provide various elements of diffusion and longitudinal back-scattering of sound energy as well as opportunities for various aesthetic designs. Canopied arrays and grouping by the installer may allow the acoustical consultant to design and achieve non-periodic responses and grouped sequencing.


AcoustiShell™ Curvilinear Diffuser-Reflectors are the ideal wall & ceiling treatment where sound must be reflected without absorption or conversion of energy. Some applications include:

  • Auditoriums
  • Performing Arts Centers
