Doppler Effect & Acoustic Frequency Shift Physics Calculator
Calculate observed sound wave frequency f', frequency delta Δf, and pitch shift percentage for moving sources and observers in acoustic physics and astronomy.
Calculator Inputs
Live Real-TimeObserved Frequency (f' Hz)
Frequency Shift Delta (Δf Hz)
34.59 Hz
Frequency Shift Percentage
7.86%
Source Velocity (m/s)

Detailed Calculation Breakdown
Calculation Methodology
Equation: f' = f0 * (v + vo) / (v - vs), where v is speed of sound (343 m/s at 20°C), vs is source velocity (positive when approaching), and vo is observer velocity.
