Abstract
Acoustic particle velocity sensors can be an alternative sensor category for end of line testing next to microphones, accelerometers or scanning laser vibrometers. As any other category of transducers, particle velocity sensors have their specific features.
The acoustic particle velocity field is far less susceptible to background noise than the sound pressure field, allowing acoustic testing to be carried out in a manufacturing environment with significant background noise levels [2].
Close to a vibrating surface, acoustic particle velocity is a good estimate of the normal structural velocity, allowing non contact vibration measurements [4].
The results of some case studies will be summarized.
