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 characteristics to be specified and the relevant methods of measurement.
