Protection from sound and noise
from outside - but also from inside - is becoming
increasingly important in both new constructions and
restorations. Expert advice is essential to guarantee an
appropriate level of sound insulation all over the building.
Obviously, we can close our eyes, but not our ears! Noise is
an unpleasant, undesirable or harmful sound. The philosopher
Arthur Schopenhauer (1781-1860) characterized it as follows:
‘Noise is the most impertinent of all forms of interruption.
It is not only an interruption, but also a disruption of
Sound as a physical dimension can be measured precisely.
However, noise is quite another matter. Factors such as
sensitivity and a subjective assessment of what is perceived
to be noise have a decisive role in this case. This is where
the field of psychoacoustics comes into play.
Psychoacoustics classifies the various attributes of sound,
giving them objective valuation standards, for example
‘pleasant-unpleasant’ or ‘sharp-dull’.
By the way: The unit dB (i.e. ‘decibel’ or ‘one tenth of a
bel’), which is used to measure sound, was named after
Graham Bell, inventor of the telephone. We take a systematic
approach to planning to specification, providing all the
services required in the field of sound insulation both
inside and outside buildings.
Our range of services in this field includes:
• Planning and proof of sound insulation in accordance with
DIN 4109, supplementary sheet 2 or VDI 4100,
and in accordance with individual requirements
• Advice on detailed planning, ceiling, wall, window, façade
and stairway construction to provide airborne,
impact and structure-borne sound insulation, including catalogue of
• Sound insulation of service installations
• Vibration insulation of service installations and other
• Protection from outside noise from traffic and commercial
• Preparation of expert evaluations
• Sound technology analysis of current situation (status quo
report) and feasibility studies
