Taken from uaudio.com “In this article, we’re going to have a close look at the tool we all use every day: the ear. This small organ has quite a few surprises in store for us. We’ll see that it’s literally crammed with equalizers and dynamic compressors, including a multi‑band one. It even includes an extremely efficient filter bank, as well as a highly sophisticated analogue‑to‑digital converter. Armed with this knowledge, sometimes referred to as ‘psychoacoustics’, we’ll discover numerous practical consequences for music production. Those include the choice of monitoring level, ideas for how to deal with bass frequencies in a mix, and a surprising antidote to frequency overlap.

Note that this article won’t attempt to cover psychoacoustics in its entirety. In particular, we’ll be restricting our focus to monaural audition and setting aside the notion of integration time, which is the audio equivalent of ‘persistence of vision’.”
