The trend towards open-plan offices is leading to growing interest in acoustic
solutions. Even if the building’s exterior is well-insulated against noise, poor room
acoustics can have a considerable impact on your staff’s productivity.
With its sound-absorbing products, REHAU helps to modify the room
acoustics to allow uninterrupted concentration in relaxing surroundings.
The product range comprises acoustic solutions for furniture fronts and acoustic
partition screen systems:

REQUIREMENTS FOR MODERN OFFICE ENVIRONMENTS
Customised near-field shielding for work stations
The average person spends around a third of their life at work. Typical
everyday life at the office: a printer clatters nearby, the phone rings on
the desk to your right, and a colleague is on the phone to your left.
Noise is one of the key stress factors in open-plan
office environments. This is not only irritating but
also has adverse effects on staff’s mental health,
accompanied by a reduction of up to 20% in
productivity.
Given that staff costs account for more than 80 %
of a business’s outgoings, this leads to significant
financial losses that no company should have to
simply endure.
The solution to this is clear: given the current
popularity of architectural design features such
as concrete and glass, the use of effective indoor
acoustics is becoming increasingly important.
When used correctly, acoustic furniture has the
versatility to significantly improve comfort in the
office, reduce stress and, in turn, boost staff
productivity.

REQUIREMENTS FOR MODERN OFFICE ENVIRONMENTS
REHAU solution
With its Acoustic Solutions, REHAU has developed a range
of effective products that suppress noise directly at source
while simultaneously functioning as acoustic screens to
prevent its dispersal. Efficient and attractive solutions for
a customised acoustic office environment – acting primar­
ily in the near field and therefore more effective than
measures in the far field.

ACOUSTIC SOLUTIONS FOR FRONT PANELS
RAUVOLET acoustic-line & RAUVOLET fabric-line
With its unique RAUVOLET systems, REHAU has developed effective alternatives
to conventional cabinet closures.

These acoustic solutions take advantage of
the existing surfaces on the fronts of the modules,
providing efficient acoustic screening and absorption. Moreover, they achieve a smart combination of
storage space and additional functionality.
Unlike in conventional swing-out doors, the opening
mechanisms take up no additional
space in the room. The functional area specified for
furniture in DIN 4534 is therefore unnecessary.
The patented RAUVOLET acoustic-line multielement shutter system, already widely in use,
impresses as a highly effective broadband absorber
in absorber class B (αW=0.8).
Thanks to its textile surfaces, the unique
RAUVOLET fabric-line textile cabinet closure
combines cosiness and acoustic comfort within the
living space. Sound absorption class B (αW=0.8)

ACOUSTIC SOLUTIONS FOR FRONT PANELS
Too much office noise?
Office work always involves a trade-off between concentration and
communication. Acoustic screening and noise absorption can help deliver
constructive acoustic conditions in the work space. Here, we explain what
this means exactly:
Sound absorption
Effective absorbers can be used to achieve significant reductions in sound pressure levels
and reverberation time.
In doing so, they absorb the sound energy and convert it into other forms of energy.
It is advisable to use so-called broadband absorbers, which absorb sound uniformly across
the entire relevant frequency range. The sound absorption rate is used as a measure of a material’s
absorptive capacity and ranges from αW = 1 (complete absorption)
to αW = 0 (complete reflection).
A = ultra-absorbent,
αW: 0.90–1.0
B = ultra-absorbent,
αW: 0.80–0.85
C = highly absorbent,
αW: 0.60–0.75
D = absorbent,
αW: 0.30–0.55
E = weakly absorbent,
αW: 0.15–0.25
Complete sound absorption
Partial sound absorption
Complete sound reflection
Acoustic screening
As a rule, sound disperses spherically from an acoustic source in all directions.
Acoustic screening elements, such as partition walls, desk panelling or cabinets with acoustic front panels,
interrupt the sound’s direct path from the acoustic source to the receiving end. For effective
acoustic screening – e.g. from the person sitting at the next station – the acoustic screen should be
positioned immediately next to, or around, the acoustic source.
17
RAUVOLET acoustic-line
The all-rounder: the patented RAUVOLET acoustic-line multi-element shutter
system, already widely in use, performs impressively as a highly effective broadband absorber and ensures complete concentration in all office environments.
Moreover, the closure offers unrestricted access to the entire contents of the
cabinet.
Highly effective class B
broadband absorber
RAUVOLET acoustic-line absorbs
sound linearly across the entire frequency
range. Its sound absorption rate of 0.8
means up to 80 % of incident sound is
absorbed.

For a relaxing ambience
Thanks to its homely fabric surface, the
textile cabinet closure ensures greater
comfort in the workplace. Its design
clearly sets it apart from conventional
multi-element shutter systems.
For effective acoustics
By combining our highly effective RAUVOLET
acoustic-line multi-element shutter system with
a sound-permeable fabric, the RAUVOLET fabricline acts as a highly effective class B broadband
absorber (αW=0.8) whilst contributing to a pleasant
office atmosphere.

In comparison with other screen and partition
systems, the RAUWORKS range impresses in two
ways. The systems specific structure and thickness
ensure greater efficiency of sound absorption in
the near field. The second advantage is the system
height, which at 70 cm reduces the spread of
sound to colleagues in surrounding areas.
This allows RAUWORKS to deliver a better acoustic
performance than thinner, smaller systems.
The sound-absorbing 1 RAUWORKS desk screen
system was designed especially for use at double
work stations. For example, RAUWORKS split
screen impresses with versatile shielding thanks to
its individually height-adjustable dividing
elements that – when lowered – enable easy
communication between colleagues and –
when raised – allow uninterrupted concentration on the task at hand.
Sound absorption class B/C (depending on the
system, the sound absorption rate αW is between
0.75 and 0.85).
The RAUWORKS partition 2 partition wall system
allows not only flexible zoning within open-plan
offices, but also improves the room’s acoustic
conditions. Whether alone or positioned in groups
– RAUWORKS partition achieves optimum acoustic
and visual privacy in all situations.
Sound absorption class B (αW = 0.8)
A beading connection allows versatile and straightforward replacement of the fabric cover. This allows
you to easily customise and install replacement
covers on your existing system.

How does RAUWORKS affect the acoustics of office spaces?
A study by the Institute for Building Services and Energy Design at the TU Braunschweig
in collaboration with REHAU
In order to test the effect of RAUWORKS screen and partition systems, the modern office and meeting rooms at the
TU Braunschweig were furnished with REHAU products. During the testing phase, which lasted one year, it became clear that
RAUWORKS systems were able to demonstrate a clear improvement in room acoustics and the occupants general well-being.
