Beschreibung:
In the case of complex periodic tones, several simple tones overlap to create one “overall tone" (sound).
With the violin, several simple tones overlap their upper harmonics to form “sounds" and the sounds and tones of several strings form complex “tone and sound mixtures". A complex periodic sound signal is formed through the combination of simple harmonics or partial tones.
Information and ideas:
Possible cross reference: Examination of aperiodic speech signals with the help of spectral analysis.
