EBU Technology & Innovation – ‘EBU Mode’ metering to supplement EBU R loudness normalisation
Complaints to broadcasters about the intrusive level of interstitials programs advertisements, commercials has resulted in projects to develop such meters. One such device was developed by CBS Laboratories in the s.
Loudness monitoring – Wikipedia
Traditional methods of measuring signal levels, such as the Peak programme meter and VU meterdo 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.

The need for proper loudness monitoring is apparent in the loudness war that is now found everywhere in the audio field, and the extreme compression that is now applied to programme levels.
Audio engineering Broadcast engineering Sound production technology Sound recording Broadcasting stubs Sound technology stubs. Loudness monitoring of programme levels is needed in radio and television broadcastingas well as in audio post production.
Meters have been introduced that aim to measure the human perceived loudness by taking account of the equal-loudness contours and other factors, such as audio spectrum, duration, compression and intensity.

Based on loudness metering, many manufacturers have developed real-time audio processors that adjust the audio signal to match a specified target loudness level that preserves volume consistency at home listeners.
