Psychoacoustics: Where Sound Meets Your Brain
In this article, Emmanuel Deruty (Sound on Sound) has a close look at psychoacoustics and the human ear. He shows that it’s literally crammed with equalizers and dynamic compressors, including a multi‑band compressor. It even includes a filter bank, as well as a highly sophisticated analogue‑to‑digital converter. Having this knowledge has practical consequences for music production: topics like choice of monitoring level, how to deal with bass frequencies in a mix, and how to deal with frequency overlap are all covered in the article. Miss this, and you’ll miss out!
- The ear includes a built‑in analogue‑to‑digital converter.
- The reverberation of the auditory canal boosts frequencies around 3 kHz by 15 to 20 dB.
- The human ear can withstand a dynamic range of roughly 140 dB, which corresponds to a ratio of 100,000,000,000,000:1 between the loudest and the quietest sounds we can perceive.
- On midrange: The ear privileges the frequencies around 0.5‑4 kHz. Get your message across right there.
- Harmonics include more information about the pitch of a sound than does the fundamental frequency.
