Annotation of standard text IEC 60268-22-ed.1.0 :
IEC 60268-22:2020 applies to transducers converting an electrical input signal into a mechanical or acoustical output signal. However, if the electrical input terminals and the surface of the radiator are accessible, this document can also apply to passive and active sound systems such as loudspeakers, headphones, TV-sets, multi-media devices, personal portable audio devices, automotive sound systems and professional equipment. This document describes only electrical and mechanical measurements that help assess the transfer behaviour of the device under test (DUT). This includes operating the DUT in both the small- and large-signal domains. The influence of the target applications acoustical boundary conditions (e.g. car interior) can also be considered in the physical evaluation of the sound system. Perception and cognitive evaluations of the reproduced sound and the impact of perceived sound quality are outside the scope of this document. LIEC 60268-22:2020 sapplique aux transducteurs qui convertissent un signal dentree electrique en signal de sortie mecanique ou acoustique. Toutefois, si les bornes dentree electriques et la surface du radiateur sont accessibles, le present document peut egalement sappliquer aux systemes electroacoustiques passifs et actifs tels que les haut parleurs, les casques decoute, les televiseurs, les appareils multimedias, les appareils audio personnels portables, les systemes electroacoustiques pour automobile et les equipements professionnels. Le present document ne decrit que les mesurages electriques et mecaniques qui aident a evaluer le comportement de transfert de lappareil soumis a lessai (DUT). Cela comprend le fonctionnement du DUT dans les domaines des signaux faibles et des signaux forts. Linfluence des conditions de limite acoustique de lapplication visee (par exemple, habitacle dun vehicule) peut egalement etre prise en consideration dans levaluation physique du systeme electroacoustique. La perception et les evaluations cognitives du son reproduit et limpact de la qualite acoustique percue nentrent pas dans le domaine dapplication du present document.
