(Main)Sound system equipment - Part 23: TVs and monitors - Loudspeaker systems
Sound system equipment - Part 23: TVs and monitors - Loudspeaker systems
IEC 60268-23:2023 specifies acoustical measurement methods that apply to TV sets, monitors with built-in loudspeakers, and other audio devices having similar acoustical properties (e.g. flat-panel loudspeakers). The acoustical measurements are performed under free-field conditions and in-situ. This document does not assess the perception and cognitive evaluation of the reproduced sound, nor the impact of perceived sound quality.
Elektroakustische Geräte - Teil 23: Fernsehgeräte und Monitore - Lautsprecher Systeme
Équipements pour systèmes électroacoustiques - Partie 23: Téléviseurs et moniteurs - Systèmes de haut-parleurs
L'IEC 60268-23:2023 spécifie des méthodes de mesurage acoustique qui s'appliquent aux téléviseurs, aux moniteurs avec haut-parleurs intégrés et à d'autres appareils audio qui présentent des propriétés acoustiques similaires (haut-parleurs plats, par exemple). Les mesurages acoustiques sont réalisés dans des conditions de champ libre et in situ. Le présent document n'évalue pas la perception et l'évaluation cognitive du son reproduit, ni l'incidence de la qualité perçue du son.
Oprema zvokovnega sistema - 23. del: Televizijski sprejemniki in monitorji - Sistemi zvočnikov (IEC 60268-23:2023)
Standard IEC 60268-23:2023 določa metode akustičnih meritev, ki se uporabljajo za televizijske sprejemnike, monitorje z vgrajenimi zvočniki in druge zvočne naprave s podobnimi akustičnimi lastnostmi (npr. ploskovni zvočniki). Akustične meritve se izvajajo v pogojih prostega zvočnega polja in na mestu uporabe.
Ta dokument se ne uporablja za ocenjevanje zaznavanja ter kognitivno vrednotenje reproduciranega zvoka in vpliva zaznane kakovosti zvoka.
