Specification for electroacoustics. Instruments for the measurement of sound intensity. Measurement with pairs of pressure sensing microphones Ingestion-build-224916 when much measurement data has1 Scope The primary purpose of this Standard is to ensure the accuracy of measurements of sound intensity applied to the determination of sound power in accordance with ISO 96141. To meet the requirements of that standard, instruments are required to analyse the sound intensity in one third octave or octave bands, and optionally to provide required to measure sound pressure level in addition to sound intensity level to facilitate the use of the field
