diffusion / absorption

Description:

OptiDi system diffuses sound in mid and high frequencies, most effectively as a combination of positive and negative modules. Due to internal filling and variable slots’ width, bass absorption may be adjusted to a particular frequency of choice. OptiDi is usually used on walls but it can be designed for ceilings or as a portable panel as well.

Sound absorption coefficient:

αw, max = 0,20

Application:

  • concert halls
  • philharmonic halls
  • theater halls
  • opera houses
  • rehearsal rooms
  • recording studios
  • control rooms
  • radio and TV emission rooms
  • lecture halls
  • classrooms
  • conference rooms
  • waiting rooms
  • offices
  • dedicated listening rooms

Custom-made:

Usually custom-made due to specific absorption needed.
Ceiling structure and mobile version possible. Various depth and bass absorption properties on demand.

Fire safety:

Made of materials with flammability class A0.

Additional information:

Optidi system was developed in cooperation with AGH University of Science and Technology.
Registered Community Design number: 004417723-0001 and 004417723-0002.
