As of September 2012 a number of areas have adopted a recent ITU recommendation on a loudness (rather than level) based form of metering and specification for broadcast.To get the best out of our equipment, we need to understand how it works and interconnects this means knowing about the various different dB scales we will encounter, and how they should align.This is particularly true if we tire our ears out with working – it becomes harder to make reasonable decisions. Our judgement of frequency balance and loudness is not constant with time.The levels at which we monitor in the studio have an impact on how we hear our work, and consequently on how the work translates to different spaces and systems, because our relative perception of frequency is not constant across different levels.Our perception of loudness is not constant (or even remotely linear) at different frequencies, so it is possible to have high level signals that nonetheless sound weak (and vice versa) depending on their frequency content.
Understanding this relationship turns out to be very important to us as designers of sound for a number of reasons: In Lecture 1 you were introduced to the complex relationship between sound level and perceived loudness. If you wish to jump straight to that and read the text later, then click here Note: There is an embedded video near the bottom of the post that provides a comprehensive and accessible introduction to the new EBU loudness standards.
