For a sound wave: A car is moving towards a person at 50m/s and toots its horn. Let's say the speed of sound relative to the air is 340m/s. Does the person measure the speed of the sound to be 390m/s or does it remain at 340m/s?

Stilll 340 m/s, but the frequency of the horn will be Doppler shifted up.

Excellent, thanks for the help.
