Abstract
The paper presents a mathematical analytical justification of the scheme of a small-sized acoustic probe of pressure pulsations insensitive to changes in the average pressure. An option of engineering implementation of a device for measuring pressure pulsations in high-temperature conditions is described. Amplitude-frequency characteristics of a small-sized probe at various values of the average pressure in the unit under test are given.
