Diffraction Hole Absorber (DHA)
The Diffraction Hole Absorber (DHA) panels provide a wider architectural pallette to the acoustician and architect. These panels are constructed of real wood veneers with a variety of hole patterns, including microperf, for tuning the acoustic needs of a room.
The DHA is a single hole product while the DHA/T is a T-hole product providing a wider absorption curve while maintaining a smaller, less visible hole in the front of the panel. Front perforations as small as 2mm are available.
