This standard BS EN IEC 60268-23:2023 Sound system equipment is classified in these ICS categories:
33.160.01 Audio, video and audiovisual systems in general
33.160.50 Accessories
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.
