[Aesthetics and Functionality] The panel has been specially developed for situations where acoustic absorption and greater visual sophistication are required, such as offices, meeting rooms, home offices, dining rooms, recording studios, podcast booths, and more. By dampening unwanted sounds such as echoes and noise, you can get much clearer sound. [What effect does it have?] The tiles are a simple, elegant acoustic solution for almost any space. Thanks to the high density, the tiles are excellent for reducing background noise, echoes, reverberation time (RT) and reducing standing waves, improving speech intelligibility and helping to increase sound clarity in a room or space.
