What is it for?

Traditional PPM level meters (Program Peak Meters) were designed for analog production. They were tools to drive the AM and FM transmitters as far as possible without overmodulation.


But PPM meters do not measure how loud a listener will perceive a specific piece of your program.


Why Loudness?

Applying the same levels to different program signals does not normally result in the same Loudness impression. This is especially evident when comparing music and speech. 
The subject of loudness has been under discussion for a long time, and many attempts have been made to design a meter that gives a reading that correlates to our hearing.


The European Broadcasting Union (EBU) has a recommendation for Loudness measurements called EBU R128, which is being implemented by all European Public Broadcasters over the coming years.

The International Telecommunication Union (ITU) has a separate Loudness measurement standard called ITU-R BS.1770. It is very close to R128 but not quite the same at time of writing (March 2016). US public broadcasters, with PRSS as the fulcrum, have agreed on a standard Loudness target level of -24 LUFS using the ITU standard for radio.


Transom has a great explanation of how to implement Loudness in your productions.


The Loudness Meter in the Hindenburg product line follows all EBU R128 and ITU-R BS.1770-3 recommendations.
