1. Loudness, volume, level, amplitude, gain, drive - Is there a difference?

In this brand new module, we'll try to answer the question of how loud a sound is. As we dive through this module, we'll quickly find out that answering this question is not as easy or intuitive as it seems. But before delving into the concept of measure of levels and the human perception of loudness, we'll take a look at the obscure and often and often overloaded terminology used in acoustics to represent the general concept of how loud a sound is. Loudness, volume, level, amplitude, gain and drive.

In this module on Loudness and Level we'll delve into how our sense of loudness is different for different frequencies and all the nuances associated with hearing. We'll look at level, and the technical ways of measuring and calculating the amplitude of signals. And finally we’ll look at a new way of measuring loudness that’s all the rage at the moment, the Loudness unit. It has redefined the standard used in streaming and broadcast, and promises to bring an end to the age of super compressed audio and the so-called loudness war.
