More about: Doppler Effect (Sound)

What it calculates

The “Doppler Effect (Sound)” calculator computes Observed frequency in Hz from 3 parameters: source frequency (Hz), source speed (m/s), sound speed (m/s).

A standard physics formula used in educational and engineering tasks.

Example calculation

With parameters Source frequency = 440 Hz, Source speed = 30 m/s, Sound speed = 343 m/s the result is 482.17 Hz (f = f₀·c/(c−v)).
