What 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 for other comparisons among aircraft models.
BS EN IEC 61265 provides methods by which tests can be made periodically to verify that the performance continues to conform to the requirements within stated limits.
The sound measurement system mentioned in BS EN IEC 61265 comprises a combination of instruments extending from a microphone, including its windscreen and other accessories, through data recording and processing devices to a suitable output.
Different measurement systems, regardless of their composition, perform the necessary functions in different ways and operate on either analogue or digital principles.
