Siuakustik Type 28/4 wooden grooved acoustic panel provides high acoustic absorption in low and mid frequencies. Groove distance is 4mm in front of the panel.  

The distance between each groove is 28mm. There are 2000holes/m² at the back of this model. The diameter of each hole is 10mm. Perforation ratio is 7.5% is an effective noise absorption element especially in the frequency range up to 500 Hz. The option of T-perforation enables a good flattened noise absorption over the entire frequency range from 125 to 4000 Hz. Therefore adequate for basically all frequency ranges.

Siuakustik Type 28/4 Panels can be installed by stapling to a timber batten or clamping to siuakustik Omega profile with clips.
