Noise with a sharp spectral peak is perceived as pitched.
Evidence
In addition to periodic signals, non-periodic signals may also give rise to a perception of pitch in many situations. A band-pass filtered noise signal with a single spectral peak is perceived to have pitch corresponding to the centre frequency of the peak. The salience of pitch perception is better the narrower the peak is. β Ville Pulkki, Matti Karjalainen, Communication Acoustics- Anβ¦, 1106
