The ear’s analysis resembles Fourier frequency decomposition of sound

Evidence

Representing signals in the frequency domain, as decompositions into their frequency components, is important not only as a powerful signal processing technique but also because it resembles the way the human ear analyses signals. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 377
