Anechoic Chamber* University Oldenburg, Germany
This room of the dimensions 8.50 x 7.00 x 4.00 m3
(measured from wedge-tip to wedge-tip), equipped with foam-wedges
of about 1.5m in depth, fulfills the requirements for free-field
measurements down to a lower limiting frequency of 50Hz.
It is enclosed in a rigid cement housing, which is mounted on springs
inside a separate building.
The resonant frequency of the mass-and-spring system lies below 5Hz.
