Abstract
The paper presents the methodological features of measurements to determine the acoustic radiation of model panels in the field of aerodynamic pressure fluctuations. The fundamental possibility of application of intensity measurement in the near field of a vibrating surface is demonstrated. The article presents the significant influence of static loading of the panel on its acoustic radiation in the vicinity of the first resonant frequencies and a significant weakening of this influence with increasing frequency.
