WS01

The WS01 is a test device to determine the sound absorption coefficient and impedance in impedance tubes

This special impedance tube allows measurements on large square samples.
Sound absorbing materials measuring up to 200x200mm (max. thickness = 250mm) can be measured in the WS01.

This also makes the WS01 very suitable for samples with large structures / shapes.
The WS01 measures in the frequency range of 50-2500 Hz.
