Computational models extract quantitative metrics for the ear’s perceptual dimensions

Evidence

As discussed in previous chapters, the fundamental psychoacoustic theory of hearing describes the peripheral hearing system as a kind of spectral analyser that extracts several perceptual aspects like specific loudness and overall loudness, pitch, duration, sharpness, and roughness, to mention a few, from the ear canal input. Since each of these aspects can be described in a quantitative manner depending on the properties of the input signal, computational models can be designed to extract metrics related to these aspects and, consequently, to emulate the functionality of hearing at least to some extent. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1572
