Sound system equipment. Methods for measuring and specifying the performance of sounders (electroacoustic transducers for tone production) Ingestion-build-201039 Part 5: Welded cold sized1 Scope and object This International Standard is applicable to sounders, which are treated as entirely passive electroacoustic transducer elements. Piezoelectric diaphragms, which are the principal components of piezoelectric sounders, are also included. Buzzers which are sound sources with built in electric circuits are excluded. The object of this standard is to standardize the definitions relating to these electroacoustic transducers, and to list
