Original Abstract

This paper deals with real measurement results on simply supported steel beam producing sound field in short distance from the beam surface. Beam resonant frequencies can be calculated analytically, measured with classical piezoelectric transducers with information about acceleration on the beam, and also with microphone array and near-field acoustic holography calculation. The non-contact technique with microphone array measurement has many advantages in compare with classical measurement with accelerometers.
