`1/fnoise' in music and speech
Abstract
THE power spectrum S(f), of many fluctuating physical variables, V(t), is `1/f-like', varying as f-γ (0.5<~γ<~1.5), over many decades of frequency (see ref. 1 for review). We have found that loudness fluctuations in music and speech, and pitch (melody) fluctuations in music exhibit 1/f power spectra.
