Annotation A physical model with a capacitor for excitation of long-wave longitudinal and surface acoustic waves in metals has been developed. It is shown that the model allows the calculation of the output signal and choice of methods and means for receiving data from acoustic oscillations during the defectoscopy of metals. The possibility of long-wave excitation and reception of acoustic oscillations of capacitive transducers are defined. Solution of the electronic device for implementing the original capacitive acoustic defectoscopy method s designed.
