alpha AKUSTIK is the acoustics brand of Staudigel GmbH from Veitshöchheim — a family business with over 70 years of experience in wood processing. On around 7,500 m² of production area the company manufactures sound-absorbing perforated, slotted and micro-perforated panels (NANOLITE) on an MDF base for wall and ceiling. The panels are built up with a backing acoustic fleece (SoundTex) and mineral insulation into acoustically effective claddings. The range spans from discreetly perforated visible surfaces to highly absorbent slot-and-hole patterns and is broadly documented by accredited reverberation-chamber measurements (Fraunhofer IBP, BAE Fiedler, ita).
WebsiteALPHA-AKUSTIK Slotted Panel (inner groove 20/N10) & WAVY
The slotted acoustic panel of the inner-groove type (20/N10) by alpha AKUSTIK: an MDF panel with narrow visible slots and a rear groove, backed with acoustic fleece. The fine line look stays calm while the rear groove enlarges the sound-absorbing area. Tunable via slot pattern (e.g. 20/N10-16-2) and backing, from medium to very high absorption. This range also includes the three-dimensional WAVY wall lining.
