Résumé

On décrit les plus récents travaux en recherche et développement sur l'étalonnage primaire acoustique au CNRC. On discute notamment de 1‘instrumentation et de l'appareillage pour l'étalonnage des microphones à condensateur par les méthodes de comparison et de réciprocité précise. On présente aussi une technique en cavité à trois orifices utilisant deux microphones pour l'étalonnage total des sonomètres ainsi que diverses méthodes de vérification des calibrateurs acoustiques.
