Acoustic data

A felt relief that absorbs sound

Dunes are made of Pro.Felt acoustic felt. Our flat panels use the same felt. Its absorption chart is alongside.

Reliefup to 100 mm
  • Less reverb and echo.
  • Each module has 50 felt slats.
  • The modules join into one consistent wall.
Sound absorption coefficient α

The chart shows the absorption of Pro.Felt felt. The slats and the base are made of this felt. It was measured as for flat panels, at 23°C and 48% humidity.

Construction

Felt slats on a felt base

Each module has 50 slats set every 24 mm. The slat height changes smoothly, and this creates the dune pattern.

  1. A 9 mm felt base

    A flat 600 × 1200 mm board of PET acoustic felt. The slats stand on it.

  2. 9 mm slats every 24 mm

    50 slats per module. Each has a different profile and rises up to 100 mm above the base, so up to 109 mm from the wall.

  3. Eight modules A1–B4

    The pattern runs from one module to the next. Eight modules make a 2400 × 2400 mm wall.

  4. Wall mounting

    With plugs, included in the set.
