The paper presents a study of wave processes occurring in the experimental
measuring acoustic probe. The probe is designed for contactless measurement of linear dimensions
and micro-movements of physical objects using acoustic oscillations in the sound range. In the
course of the study, an equivalent circuit of the probe in the form of a T-link band electric K-filter
was drawn up. According to the design geometric parameters of the acoustic probe, the electrical
parameters of the K-filter components are calculated. To verify the theoretical results, a set of
experimental equipment was developed, and a method of experimental research was developed.
Experimental studies have confirmed the possibility of designing acoustic probe using the proposed
method of calculating the geometric parameters of its elements.
