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

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.

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

Spécifie les caractéristiques électroacoustiques des systèmes instrumentaux utilisés pour la mesure des bruits dans le cadre de la certification acoustique des avions et recommande des méthodes d'essais de vérification périodique qui permettent de s'assurer du maintien des caractéristiques en conformité avec les prescriptions, à l'intérieur des tolérances spécifiées. Les prescriptions s'appliquent aux instruments destinés à la mesure du bruit produit par des avions de transport à réaction ou à hélices de masse maximale certifiée au décollage de plus de 9 000 kg, ou par leurs systèmes de propulsion lorsque ceux-ci sont placés sur des bancs d'essais statiques installés en plein air.

FOREWORD
1) The IEC (International Electrotechnical Commission) is a world-wide organization for standardization comprising all national
electrotechnical committees (IEC National Committees). The object of the IEC is to promote inte rnational cooperation on all
questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, the
IEC publishes International Standards. Their preparation is entrusted to technical committees; any IEC na tional committee
interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental
organizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International
Organization for Standardization (ISO) in accordance with condi tions determined by agreement between the two organizations.
2) The formal decisions or ag reements of the IEC on technical matters, prepared by technical committees on which all the Na tional
Committees having a special interest therein are represented, express, as nearly as pos
