BVS Akustik GmbH & Co. KG from Verl (East Westphalia) has been active in the furniture industry since 1990 and produces custom acoustic panels with CNC saws, purpose-built drilling lines and an in-house laser system. Almost all board materials are processed: solid wood, veneered, composite and decor boards, each cut, edge-finished and lacquered to the customer's specification. The range covers drilled (AKUSTIbohr), micro-perforated (AKUSTIpur), slotted (AKUSTIpan) and sound-absorbing partition elements (AKUSTItrenn), each in numerous hole patterns and build-up depths. The elements are available in fire classes B1 and B2 and, for sports halls, with certified ball-impact resistance. References include Princeton University, NYU and the Emser Therme.

AKUSTIbohr micro
AKUSTIbohr micro is a micro-drilled acoustic panel from BVS that removes the trade-off between appearance and acoustic performance. It is produced from a wide range of carrier boards with veneers, an extensive selection of lacquers, decors and coatings in concrete, stone or rust looks, so wood grain and surfaces keep their natural expressiveness. The holes are drilled without visible edges and are practically invisible: the standard diameter is 1 mm, with 1.5, 2 and 2.5 mm also available, alongside grids of 4, 4.8, 6 and 8 mm and a staggered 6/3 mm grid. The panel can be perforated over the full surface or with unperforated edge margins, cuts and cut-outs are possible directly on site, and the maximum dimensions are 4080 mm length, 2100 mm width and 21 mm thickness. The smooth, micro-perforated surface reduces the risk of injury and avoids visual irritation; together with the certified ball-impact resistance it can also be used close to floor level. Acoustically, AKUSTIbohr micro only works through the interplay of perforation and the depth of the build-up behind it: the hole pattern and the distance to the wall or ceiling behind determine in which frequency range sound is converted into heat. Sound absorption is measured in the reverberation room per EN ISO 354 and rated per EN ISO 11654. For design work the full third-octave curve matters alongside the weighted single-number rating, because only its shape shows how the panel actually performs at low, mid and high frequencies.

Completed projects with AKUSTIbohr micro
New York · 2017
The NYU Kimmel university hospital in New York received a distinctive, acoustically effective balustrade construction for its five-storey entrance hall, running from the first to the fourth floor. Veneered acoustic panels with an AKUSTIbohr micro perforation were fitted to the substructure of the balustrade. To refine the appearance further, the larch-veneered acoustic panels were fitted with solid wood battens in a modern ribbed look.
Jordan · 2020
This state-of-the-art office complex was fitted with more than 1,600 m² of AKUSTIbohr micro panels. Each square metre received 125,000 holes with a diameter of 1 mm. In the offices and meeting rooms, the panels create a pleasant working atmosphere.
Offenbach · 2020
For this high-quality building, the covered courtyard was fitted with acoustic elements made from AKUSTIbohr micro. More than 280 façade and reveal elements were produced for it. A large part of the components was mitre-folded and bonded in the factory. The acoustic elements create a pleasantly quiet atmosphere.
Darmstadt · 2015
This sports hall in Darmstadt was fitted with AKUSTIbohr micro impact walls. What makes this sports hall special are the silhouettes of athletes perforated into the impact walls with a larger hole diameter. The higher open area makes each silhouette appear like a shadow on the walls. The silhouettes run continuously across several panels.
Rietberg · 2014
AKUSTIbohr micro panels were used as impact walls for the refurbishment of the listed Emsturnhalle in Rietberg, which dates from 1892. The new impact walls integrate harmoniously and connect the old with the new. At the same time, this combination provides lastingly pleasant acoustics for sport.
