Beat Frequency Calculator

Find the beat frequency of two tones.

Beat frequency (Hz) 4

Formula: beat = |f₁ − f₂|

Step-by-step with your numbers:

1. Values used:

2. Frequency 1 = 440 Hz

3. Frequency 2 = 444 Hz

5. Beat frequency = 4Hz

Did we solve your problem today?

Two close frequencies produce a pulsing 'beat' at their difference.

The math behind it

beat frequency = |f₁ − f₂|.

440 & 444 Hz → 4 Hz beat.

Tuning use?

Musicians tune by reducing the beats to zero.
