Most of the renowned research facilities
worldwide appreciate the advantages of an absorbent
wedge type lining system due to its high fidelity. The special
shape of the wedge absorbers offers a good impedance match
and low reflection combined with the advantages of a large
absorbing surface. If you have to deal with narrow band
or even sine sources, the wedge type lining is the only
way to ensure sufficient absorption over a wide frequency
range. After yeas of extensive research and development
the required lining depth of modern wedge type systems is
much lower than demanded by the traditional λ/4 rule of
thumb.
In
addition to theoretical design layout of anechoic chambers,
Kapolnek GmbH regularly carries out measurements in the
KUNDT tube, which allows PK anechoic rooms stand out for
their high fidelity and best possible approach to free-field
conditions allowing even lower deviations from the inverse
square law than stated in ISO 3745.
