Beat Frequency Calculator — Formule
## Beat Frequency
When two waves of slightly different frequencies overlap, they produce a pulsating amplitude variation called beats.
### Formula
**f_beat = |f1 - f2|**
The beat period is **T_beat = 1 / f_beat**. Beats are commonly used by musicians to tune instruments.

Exemple Résolu
Two tuning forks at 440 Hz and 443 Hz played together.
- f_beat = |f1 - f2|
- f_beat = |440 - 443|
- f_beat = 3 Hz
- T_beat = 1 / 3 = 0.333 s
