sound

means that there is now
an interesting lightweight
alternative for the high-frequency resonators in the air
intake systems that combats
the annoying turbo noise.
All in all, Röchling precisely
matches the engine sound to
the requirements of vehicle manufacturers. From a
smooth and balanced sound
to a powerful and sporty
one, sound design is used
to achieve optimum sound
quality.

A new structure
for more comfort
In the new field of complete
car body elements made
of composites, Röchling
sustainably generates - and
makes full use of - comprehensive optimization potentials. A multi-layer car body
floor made from StraturaTM
is one of the company's newest solutions in this field.
In production, the expert
in lightweight construction and acoustics uses its
innovative SoftloftingTM

technology and combines
two functions. As a result
of using LWRT sandwich
structures, the combination of acoustically and
thermally insulating layers,
as well as integrated stabilizing aluminium elements,
provides an optimized
NVH behaviour. For the
first time ever, the supplier
presented the integration of
aluminium profile elements.
With a field of action that
rapidly takes effect upwards
of a 500 Hz frequency, the
LWRT material reduces
ambient noise significantly.
The multilayer car body
floor also offers protection
against stone chipping and
corrosion while providing

of 6dB(A), and up to 10dB(A) in certain frequency ranges

very good crash characteristics and low weight. This
solution is innovative in
terms of design and material, and its excellent acoustic
properties not only increase
passenger comfort, but also
mean less noise on the road.

Acceleration without
splashing noises
As a result of the increasingly stringent global exhaust
standards and the associated
increase in the demand for
selective catalytic reduction (SCR) tank systems,
the company launched an
acoustically optimized SCR

tank for the first time ever.
In selective catalytic reduction, a urea solution is used
to transform nitrous oxides
in the exhaust gas into
nitrogen and water without
forming undesired by-products. In the tanks required
for this solution, energy-intensive noise often occurs at
high accelerations. As one
of several improvements
in the field of SCR tank
systems, targeted anti-splash
measures provide for more
driving comfort. n
