Categories of Beat Frequency Calculations:
| Category | Range (Imperial) | Interpretation |
|---|---|---|
| Slow Beat | 0 – 5 Hz | Like a relaxed heart rate, calm and steady. |
| Medium Beat | 5 – 20 Hz | The groove is picking up – moderate excitement. |
| Fast Beat | 20+ Hz | Heart-pounding, like a drum roll at a concert! |
Beat Frequency Examples:
| Individual | f1 (Hz) | f2 (Hz) | Beat Frequency (Hz) | Calculation |
|---|---|---|---|---|
| Calm Carl | 10 | 9 | 1 | “Carl’s heartbeat is as steady as a metronome!” |
| Groovy Grace | 15 | 13 | 2 | “Grace’s groove is getting groovier!” |
| Drummer Dave | 100 | 120 | 20 | “Dave’s drum solo is out of this world!” |
Different Ways to Calculate Beat Frequency:
