Over deze norm
||Geluid, beeld en multimedia-apparaten en -systemen
NEN-EN-IEC 62777 applies to directional loudspeaker array systems of any kind, and to the parts of which they are composed or which are used as auxiliaries in such systems. This standard deals with the determination of the performance of directional loudspeaker array systems, the comparison of these system types, and the determination of their proper practical application, by listing the characteristics which are useful for their specification. It specifies uniform measurement methods for these characteristics. This standard is restricted to a description of the audio space around a person and the relevant method of measurement. It does not consider characteristics of loudspeakers, which are specified in IEC 60268-5.
