We'll look at sound power
We'll look at sound power as our first power quantity, and we'll find out how it's different from a field quantity like pressure. Sound power is a constant, non directional, calculated value and is quite significant in the field of acoustics. In this video, we'll see the applications of sound power as a tool for labelling, derive the formula for Sound Power Level (SWL) in decibels, and derive the formula for calculating sound pressure produced by a source of known power at any distance in an ideal space.

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.
