EN 61094-2:2009

Electroacoustics - Measurement microphones - Part 2: Primary method for pressure calibration of laboratory standard microphones by the reciprocity technique

IEC 61094-2:2009 is applicable to laboratory standard microphones meeting the requirements of IEC 61094-1 and other types of condenser microphone having the same mechanical dimensions and specifies a primary method of determining the complex pressure sensitivity so as to establish a reproducible and accurate basis for the measurement of sound pressure. This second edition cancels and replaces the first edition published in 1992. This second edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- an update of Clause 6 to fulfil the requirements of ISO/IEC Guide 98-3;
- an improvement of the heat conduction theory in Annex A;
- a revision of Annex F: Physical properties of humid air.

Electroacoustique - Microphones de mesure - Partie 2: Méthode primaire pour l’étalonnage en pression des microphones étalons de laboratoire par la méthode de réciprocité

La CEI 61094-2:2009 est applicable aux microphones étalons de laboratoire répondant aux prescriptions de la CEI 61094-1 et aux autres types de microphones à condensateur présentant les mêmes dimensions mécaniques et spécifie une méthode primaire de détermination de l'efficacité en pression complexe de manière à établir une base reproductible et exacte pour la mesure de la pression acoustique. Cette deuxième édition annule et remplace la première édition publiée en 1992. Cette deuxième édition constitue une révision technique. Cette édition inclut les modification techniques majeures suivantes par rapport à l'édition précédente:
- une mise à jour de l'Article 6 afin d'être en conformité avec les exigences du Guide ISO/CEI 98-3;
- une amélioration de la théorie de la conduction thermique en Annexe A;
- une révision de l'Annexe F: Propriétés physiques de l'air humide.
