Carrying out the above-mentioned works made it possible to ensure the stability of reproduction, storage and transmission of the size of the unit of sound pressure (Pa) in the air environment, the unit of ultrasonic pressure (Pa) in the water environment and the unit of ultrasound power (W) in the water environment by state primary standards and to create conditions for ensuring unity and traceability of acoustic measurements in Ukraine. According to the results of the NDR, the studied national standards meet the standards established in the technical documentation for standards and are suitable for use in the indicated ranges of the main parameters.
