Abstract

System errors in the method of measuring sound intensity are considered. They are based on the mutual diffraction interaction of the receivers used. It has been shown that diffraction interactions affect the sensitivity of the receivers and the sound pressure in them. The double effect of these phenomena increases the error in measuring sound intensity and limits the frequency range of both high and low frequencies. This article provides recommendations for choosing the measurement wave interval between microphones. This is important if you know the level of diffraction error limitation.
