Most of the renowned research facilities worldwide appreciate the advantages of an absorbentwedge 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 We regularly carries out measurements in the KUNDT tube, which allows Our 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.
