vitAcoustic - Acoustic absorbers for wall and ceiling

The transparent or translucent acoustic absorbers reduce reverberation times and noise levels. Almost invisible with the transparent foils the architecture inside can still be seen.
The foils are easy to install and versatile. They can be installed in front of walls and glass facades and all types of ceilings- even underneath thermoactive ceilings. It allows visions of transparency and open space to come true while meeting demands of acoustics.

Combine acoustic sound absorption with visual art pictures. The foils are spanned with springs between stainless steel bolts mounted on wall or on an aluminum frame. The advantage is that the foils can be easily replaced and maintained.
New possibilities for artists and graphic designers:
3d acoustic sound absorbing visual art picture are designed through combination of printed translucent and transparent foils behind each other.
Putting a source of light behind leads to enhanced a room design which is not possible with standard acoustic pictures.
We help you to design your individual picture, no matter if it’s just some special color, a visual art motif or a design with your logo or products or other CI elements..

The placement of sound absorbing panels has an immense influence on how noise is enhanced or reduced. In large open rooms it is necessary to refract sound through objects and furnishings for optimal sound absorption of the installed acoustic ceiling.
In less diffuse rooms sound absorbing panels on parts of walls  additionally to the ceiling enhance the overall sound absorption significantly. This also reduces flutter echoes between parallel walls.
Advisable is to position sound absorber opposite the speaker’s wall as well as installing absorbers in the room’s corners. Because direct and angular refractions with their long echo time of more than 50ms are clearly, as very much stressing echo, audible for the human ear.

Sound barrier and sound absorption between work stations and work groups:
Blocks direct sound transmission - Significantly absorb sound Still remain transparent.
Transparent acoustic absorbers installed on partitions which can be placed between work stations.
They are placed in rows of 2-4 m length between two working stations or sideboards.
The partitions are available 0.8 or 1m wide and up to 2.2 m high, lower part up to 1.27m with fabric and upper part with acrylic glass plus micro perforated foils on one or two sides, mounted with springs on stainless steel bolt.

The high level of noise absorption results from the micro-perforation. The holes in the patented foil have a diameter of approx. 0.2mm and are spaced 2mm apart. The conversion from noise to thermal energy mainly occurs at the edges of the holes. Reverberation times and sound levels are reduced significantly.
We advise a distance of 30 to 100 mm to the sound-reflecting surface. Optimal effects are achieved by using two layers of acoustic foils. By having a distance of 30 mm between the two layers the acoustic spectrum of absorption is broadened.
All building materials are class B1 in accordance with DIN 4102 and therefore not easy ignitable.
The poly carbonate foil is UV-stabilized and non-static.

Akustikvorhänge, das sind transparente, bedruckte Folien, die den Reflexionsschall und die Nachhallzeit senken. Die Folien sind als Flächenvorhänge leicht und flexibel einsetzbar. Sie ermöglichen Visionen von Transparenz und Raum auch akustisch optimal zu realisieren. Die hohe raumakustische Wirksamkeit beruht auf einer vom Fraunhofer Institut entwickelten Mikroperforation. Sobald Schallwellen auf die Folien treffen, kommt es zu einer physikalischen Reaktion: Die Schallenergie wird an den Lochrändern in Wärme umgewandelt. Nachhallzeiten und Schallpegel werden deutlich reduziert. Ob in Großraumbüros, Konferenzräumen oder Eingangshallen – das Vital-Office Akustikvorhänge Konzept der transparenten individuell gestalteten Schallabsorption schafft vollkommen neue kreative Freiräume in der Bürogestaltung.

Acoustic panel curtains are transparent or translucent sound absorbing foils with print on individual motifs and images. It can be installed in front of walls and glass facades. It allows new designs of transparency and colorful structured glass facades to come true while meeting demands of room acoustics. Vital-Office® acoustic-panel-curtains absorb sound and reduce the reverberation time while at the same time are transparent or translucent and painted with stimulating motifs. The clarity of speech is increased and people adapt their speech volume to the improved quieter situation. Vital-Office® acoustic-sun protect blinds can control light and shade in
the work area, influence the internal and external effect of a building and optically structure large area window facades.

吸音挂帘是用透明的印刷薄膜制作 的,它具有减低反射声波和混响时 间的作用。 该挂帘可以灵活地挂在窗前或墙壁 上。除了优化室内的音响效果之 外,同时还以透明表面上的设计和 颜色,展现出完美的视觉效果。 基于弗劳恩霍夫研究所发明的微孔 技术,该产品具有高静音效果。一 旦声波抵达薄膜,就产生一种物理 效应:声能会在微孔边缘转化为热 量,从而降低回响和声波峰值。 无论是在超大的办公场所,还是在 会议场馆及门厅,活力办公室公司 出品的特制透明吸音制品,都能有 创意地满足装修的需要。
