Roughness from harmonics requires fundamental frequencies below 100 Hz
Evidence
Roughness (Daniel and Weber, 1997; Fastl and Zwicker, 2007) is a psychoacoustic quantity which is caused by relatively fast amplitude modulations (15β300 Hz) that take place for stimuli within the range of a critical band. For example, narrowband noise always sounds slightly rough, since there are random amplitude fluctuations in it. β Ville Pulkki, Matti Karjalainen, Communication Acoustics- Anβ¦, 1237 (
