Doppler Shift Calculator
Sound only: the observer and medium are stationary. Positive radial source speed means approaching; negative means receding. This is not a relativistic light calculation.
A QUICK WALKTHROUGH
How to use this tool
- Enter source frequency and sound speed.
- Enter signed radial source speed, with magnitude below sound speed.
- Calculate the observed frequency.
Which formula is used?
f′ = f × c / (c − v), where v is the source speed toward the stationary observer. It does not model moving observers or supersonic sources.
