EBU R 128 is a recommendation for loudness normalisation and maximum level of audio signals. It is primarily followed during audio mixing of television and radio programmes and adopted by broadcasters to measure and control programme loudness. [ 1 ]
Loudness units relative to full scale (LUFS) is a synonym for LKFS that was introduced in EBU R 128. [ 10 ] The EBU has suggested that the ITU should change the unit to LUFS, as LKFS does not comply with scientific naming conventions and is not in line with the standard set out in ISO 80000-8.

See the EBU reference (EBU R 128) LOUDNESS NORMALISATION AND PERMITTED MAXIMUM LEVEL OF AUDIO SIGNALS. An estimate of momentarily perceived peak loudness in broadcasting is meaningful only if it integrates over long enough time to properly resolve the critical band containing the lowest audio frequency component that may be 20 Hz.
Loudness monitoring of programme levels is needed in radio and television broadcasting, as well as in audio post production.Traditional methods of measuring signal levels, such as the peak programme meter and VU meter, do not give the subjectively valid measure of loudness that many would argue is needed to optimise the listening experience when changing channels or swapping disks.
If you've been shopping in a big box retail store you've probably heard an announcement on the loudspeaker such as, "code yellow toys, code yellow toys."
In 2010, the EBU published EBU R 128 which introduces a new way of metering and normalizing audio. The Recommendation uses ITU-R BS.1770 loudness metering. As of 2016 [update] , several European TV stations have announced their support for the new norm [ 16 ] [ 17 ] and over 20 manufacturers have announced products supporting the new EBU Mode ...
The loudness war (or loudness race) is a trend of increasing audio levels in recorded music, which reduces audio fidelity and—according to many critics—listener enjoyment. Increasing loudness was first reported as early as the 1940s, with respect to mastering practices for 7-inch singles . [ 1 ]
