Presented study indicates the possibility of using complex estimators of vibrational energy flow used in quality testing of concrete blocks, as part of a dedicated research methodology and detailed methodologies developed in many previous studies by the author. Theoretical analysis and practical verification of the sensitivity testing measures of complex vibration processes indicate the wide possibilities of their applications. Recognizing the need to improve the testing methods of building
