Anotation

Specifies mechanical dimensions and certain electroacoustic characteristics for condenser microphones used as laboratory standards for the realization of the unit of sound pressure and for sound pressure measurements of the highest attainable accuracy. The specifications are intended to ensure that primary calibration by the reciprocity method can be readily carried out. Establishes a system for classifying laboratory standard condenser microphones into a number of types according to their dimensions and properties. Specifie les dimensions mecaniques et certaines caracteristiques electroacoustiques des microphones a condensateur utilises comme etalons de laboratoire pour la realisation de lunite de pression acoustique et pour les mesures de pression acoustique faites avec la meilleure exactitude possible. Les specifications sont destinees a assurer que letalonnage primaire par la methode de reciprocite puisse facilement etre mis en oeuvre. Etablit un systeme de classement des microphones a condensateur utilises comme etalons de laboratoire en un certain nombre de types, selon leurs dimensions et leurs proprietes.
