Electroacoustics. Instruments for measurement of aircraft noise. Performance requirements for systems to measure sound pressure levels in noise certification of aircraftWhat is BS EN IEC 61265 Electroacoustic performance in aircraft about? BS EN IEC 61265 is standard covering electroacoustic performance in aircraft systems to measure sound pressure levels in noise certification of aircraft, to determine the noise pollution caused by aircraft. BS EN IEC 61265 specifies requirements for the electroacoustical performance of systems of instruments used to measure sound for the purposes of aircraft noise certification and
