Perceived sharpness is stable across subjects and rises with spectral centre of gravity

Evidence

When subjects are asked ‘how sharp is the sound?’ on being presented with sounds having different spectral content, a relatively stable, repeatable, and subject-independent response can be measured. The resulting response is the psychoacoustic quantity called sharpness (Fastl and Zwicker, 2007, Chapter 9). The higher in frequency the centre of gravity of the amplitude spectrum is located, the higher is the sharpness measured. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1206
