Norsonic is a leading supplier of noise
excitation equipment as well as sound measuring
systems for building acoustics. With more
than 40 years of experience and by carefully
listening to our customer’s requirements we
have developed a complete range of noise
excitation equipment. Besides, fulfilling the
technical requirements set in the ISO140 and
ISO3382 standards, our products is featuring
a unique combination of small dimensions,
low weight but yet robust and easy to use.
A field assessment often requires the
equipment to be carried up several floors. It
is therefore important that the equipment is
as small and light weighted as possible. However,
new building constructions often have a
much better sound insulation than previous
constructions. It is therefore important that
the emitted sound power is as high as
possible in order to get a good signal to noise
ratio in the receiving room. These are contrary
requirements not easy to achieve with standard
commercial equipment. Norsonic has therefore
designed extremely powerful and lightweighted
loudspeakers and a power amplifier
with equalization, ensuring that the power
is distributed to the frequencies that are
required
The Tapping Machine Nor277 follows the
same design philosophy; light weighted,
small and robust, with a weight of only 10 kg
including the battery option. It is the first
tapping machine with a build in self calibration
test for hammer fall speed and rotational
speed.
