Formula and methodology
Formula: For two ideal frequencies, beat frequency fB = |f1 - f2|.
This calculator returns the absolute frequency difference for two ideal sinusoidal components. The result is the repetition rate of the basic beat envelope under the simple superposition model; amplitude, phase, room acoustics, and instrument tuning are outside the calculation.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- First frequency — Hz; Finite nonnegative frequency in hertz.; minimum 0; maximum 1000000000
- Second frequency — Hz; Finite nonnegative frequency in hertz.; minimum 0; maximum 1000000000
Worked example
| Input | Value |
|---|---|
| First frequency | 440 |
| Second frequency | 442 |
Two frequencies of 440 Hz and 442 Hz produce an ideal beat frequency of 2 Hz.
Assumptions and limits
- Both inputs are finite nonnegative frequencies in hertz.
- The two components are treated as stable frequencies that can be superposed.
- The beat rate is modeled as the absolute difference, independent of amplitude and starting phase.
- Waveform shape, propagation medium, room response, perception, and instrument adjustment are outside the calculation.
