Composite sound

Nyquist Team
In nature, we rarely encounter perfectly pure, single tones – that's the domain of laboratories. What we hear every day – the human voice, the sound of the wind, or the tone of a guitar – are complex mixtures of frequencies that our brain interprets as a single, rich whole. Discover the anatomy of the sounds that surround us.
Professional Definition
A sound made up of at least two simple sounds.
From the point of view of spectral analysis, a complex sound is the sum (superposition) of many sinusoidal waves with different frequencies and amplitudes. In the case of musical sounds, they usually consist of a fundamental tone (determining the pitch of the sound) and a series of harmonics (harmonic tones) that give the sound its unique timbre. Fourier analysis allows us to decompose any complex sound into its basic components, which are exactly the simple tones.
Acoustics in Simple Words
A simple sound can be compared to pure flour, while a complex sound can be compared to finished dough. The dough consists of flour, eggs, sugar, and baking powder. Although you eat one piece of cake (hear one sound), it is actually a composition of many ingredients that determine its flavor (timbre). The piano and violin can play the same note (the same fundamental tone), but they sound different precisely because they have a different
