Title

Language: EN Electroacoustics - Instruments for measurement of aircraft noise - Performance requirements for systems to measure one-third-octave-band sound pressure levels in noise certification of transport-category aeroplanes

Language: FR Electroacoustique - Instruments pour la mesure du bruit des aéronefs - Prescriptions relatives aux systèmes de mesure des niveaux de pression acoustique par tiers d'octave, pour la certification acoustique des avions de transport

Abstract

Language: EN Specifies requirements for the electroacoustical performance of systems of instruments used to measure sound for the purposes of aeroplane noise certification, and recommends methods by which tests may be made periodically to verify that the performance continues to comply with the requirements given within stated tolerances. The requirements apply to the instruments used to measure the sound produced by jet-or propeller-driven transport-category aeroplanes of maximum certificated takeoff mass over 9 000 kg, or their propulsion systems when installed on a suitable outdoor engine test stand. This publication supersedes IEC 60561. The contents of the corrigendum of June 1995 have been included in this copy.
