Acoustic data
Reverb control in a decorative diamond shape
The open structure of Basotect® absorbs sound energy, helping calm the sound of the room. The chart shows curves for 3, 5 and 7 cm thicknesses - the thicker the panel, the more effective the absorption of lower frequencies.
α = 0,57at 315 Hz (7 cm)
α = 0,94at 1000 Hz (7 cm)
α = 0,98at 1600 Hz (7 cm)
- Fewer reflections support a clearer voice in recordings, streams and calls.
- The greater the thickness (from 3 to 7 cm), the better the performance at lower frequencies.
- The diamond shape lets you extend the absorbing surface in multiple directions.
- Greater thickness provides better absorption of low frequencies.
Sound absorption coefficient α
Curves for 3, 5 and 7 cm thicknesses. Conditions: 23°C, relative humidity approx. 48%; range 250-4000 Hz.

Très joli motif et pose facile au mur. Le son est moins reverbérant, dommage juste que la mousse marque vite quand on appuie.

Zamówiłem na próbę kilka sztuk i bardzo dobrze. Lekkie, kleją się od ręki, a pomieszczenie wyraźnie mniej dudni od głosu. Dorzucę jeszcze kilka.

Easy to stick up, super light, and the diamond shape actually looks like decor instead of studio foam. Echo in my office dropped right away

Sehr leicht, in zehn Minuten an der Wand und sieht echt schick aus. Der Hall im Raum ist spurbar weniger geworden.
