This paper article outlines the problems of in situ vibroacoustic testing of low-vibroactive devices. Moreover a comparison of selected methods of object's surface velocity mapping was carried out in the paper. Primary features, advantages and limitations of these methods are stated here. On the example of tests on a refrigerator the methodology and specifics of testing of this type of devices using a laser vibrometer is also shown.
