Experience with in-situ measurements using EASERA

To measure the absorption coefficients of built-in materials is quite often necessary but in reality the results deviate from those values measured in the reverberation chamber. Using the measurement platform EASERA our experiences are reported which we gathered during measurements in a big assembly hall. The measurement procedure will be explained and the needed software and hardware tools are described.
It turned out that the quality of the reference signal and the reflected one is crucial for the quality of the obtained results. Hints for the right windowing are expounded to get usable impulse responses. Also, it is explained how the selected window limits in-fluence the stability of the results.
