Abstract
The methodical features of measuring the power of acoustic radiation of model panels in the field of aerodynamic pressure pulsations are considered. We show the possibility in principle of using intensimetry in the near field of a vibrating surface. We establish the effect of static loading of the panel on the power of its acoustic radiation in the vicinity of the first resonant frequencies. It is shown that the effect decreases with increasing frequency.
