Beats & SuperpositionLive

two close frequencies interfere

Controls

Two tones close in frequency add to a wave whose amplitude throbs at the difference frequency — the beats a musician hears when tuning.

Effectamplitude throb

Governing equation

f_{beat} = ∣ f_{2} - f_{1} ∣ = ∣11 - 10∣ = 1.0 Hz

Reading this result: At a 1.0 Hz beat the throb is too fast to count as a pulse; the ear stops hearing separate beats and instead hears roughness or dissonance around the 10.5 Hz average pitch.
