BS EN 62760 discusses the audio reproduction method for normalized loudness level. BS EN 62760 specifies the audio reproduction method for normalized loudness level of audio sources for consumer equipment and systems.
BS EN 62760 describes the system model of reproduction. BS EN 62760 specifies the method is applied to the appropriate part of audio devices. For instance, a TV set may apply this model in its final stage of audio reproduction, an audio amplifier may apply this model in its first stage of audio reproduction.
BS EN 62760 on audio reproduction method is useful for:
The loudness level of audio reproduction varies according to the level of the input source and whether it is mono, stereo, or multichannel. Without a suitable form of automatic control, users are forced to adjust the volume level of equipment to obtain an appropriate loudness level when the user selects another audio source or audio mode such as mono, stereo, or downmix.
BS EN 62760 specifies the method for reproduction with channel mode level setting and other level settings and provides improved quality of listening for users. BS EN 62760 provides a method that is also applicable for various audio content other than broadcasting audio. BS EN 62760 is applicable to electrical signal levels and excludes acoustic audio levels from loudspeakers.
