Greatly improving the acoustics of a room divided using a DORMA Hüppe Variflex or MOVEO sliding, partitioning wall system, the new DORMAcoustic panels maximise sound absorption in the frequencies from 250 to 1,600 Hertz, the range most relevant for good speech audibility and intelligibility.
Exclusive in the UK to partitioning experts Style, the 22mm thick panels are constructed with a precision perforated composite surface, an acoustic fleece and an acoustic core.
DORMA Hüppes moveable walls already deliver excellent acoustic privacy between divided areas, explains Julian Sargent, MD for Style. The DORMAcoustic panels now improve the auditory ambience within each room by effectively reducing noise reverberation and increasing sound absorption.
The acoustic surfaces are available in a choice of two precision perforation patterns. With microfine perforation, the holes have a diameter of just 1.5mm, offering a sound absorption coefficient of αw = 0.50, as measured according to ISO 11654. This ensures a balanced in-room acoustic performance with no visual trade-off. With wide-band perforation, the holes are 3mm in diameter, delivering a sound absorption coefficient of αw = 0.45.
Both types of DORMAcoustic panel ensure especially good sound absorption to promote both verbal understanding and effortless listening pleasure in any interior environment.
Customized perforation designs are also possible, depicting images, graphics or ornamental patterns as required, giving the interior design unique individuality. The acoustic surfaces are also available in a variety of attractive colours and decors and surrounding fixed walls can be supplied to complement the moveable wall system.
Committed to ensuring a healthy interior environment, DORMAcoustic panels satisfy relevant health and environmental protection requirements, complying in the drilled state with class E1 as determined using the WKI test (Wilhelm-Klauditz Test per EN 717-1:2005-1), with values far below the permissible threshold according to the EU Chemicals Regulation.
