What is brown noise?
While you might not recognise the term ‘brown noise’, it’s likely you’ve heard it without realising it has a special name.
There are three main ‘colours’ of noise – white, pink, and brown (also often referred to as red).
All three forms of noise are made up of all frequencies that are audible to the human ear, but the key difference is how energy is distributed across these frequencies.
In white noise, energy is equally distributed, resulting in a consistent humming sound.
