22 / LM6 Radar Loudness Meter
Post Script
Control of loudness is the only audio issue that has made It to the political agenda.
Political regulation is currently being put into effect in Europe to prevent hearing
damageanddisturbancesfromPAsystems,andtoavoidannoyingleveljumps
during commercial breaks in television. In Australia, something similar may happen.
Many years of research into loudness of not only dialog, but also of loudness relating
to any type of audio programming, has brought TC to the forefront of companies
in the world to perform realtime loudness measurement and control. Therefore, TC

Europe and other areas.

while the total number of viewers remains roughly the same. On the sound production
side, it is therefore important that delivery criteria can be easily specified and met,
even by people not primarily concerned with audio: Journalists, musicians, video
editors, marketing professionals etc.
Using only dialog based audio measurements in digital broadcast, has led to

chain ends with the capability of quality controlling everything upstream by applying
the same loudness measure for logging purposes: A closed loop.
