In the various methods of non-destructive testing, which working with the deformation fields, diagnostic accuracy is largely dependent on the intensity of structural noise caused by small-scale irregularities of building structures. In this paper we investigate the effectiveness of using a vector-scalar receiving systems for diagnostics of vibration and defectoscopy of building structures. Comparative analysis of the fluctuations of the scalar and energy flux components of the structural noise acoustic field was conducted using computer simulation. Suppression of this noise contributes to a more precise localization of defects in constructions. The study was conducted in view of the fact that the component of the stream of the acoustic field, for which the intensity of the structural noise is minimal, is measured indirectly, using two sensors: scalar and vector. It is shown that the use of energy flux component can increase the detection efficiency.
