Doppler Effect For A Moving Observer
f' = f·(v + v_o) / v
What it says
The frequency perceived by a listener moving toward a stationary source equals the source frequency times the sum of the speed of sound and the observer speed divided by the speed of sound. The observer intercepts wavefronts more rapidly, raising the pitch.
