Measurement with pairs of pressure sensing microphones Ingestion-build-100998 This document does not imposeWhat is BS EN 61043 Sound intensity testing instruments about? BS EN 61043 is an international standard that discusses using electroacoustics techniques for sound intensity testing. BS EN 61043 describes the specifications to meet the requirements, where instruments are required to analyze the sound intensity in one third octave or octave bands, and optionally to provide A weighted band levels. They are also required to measure sound pressure levels,
