problem: Two similar speakers are driven by the same oscillator at 200Hz. They are positioned on a vertical pole and 4.00 m apart. A man walks straight towards the lower speaker perpendicular to the pole.

A. How many times he'll here a min in the sound intensity?

B. How far from the pole at such moments?

Use speed of the sound 330m/s and avoid the reflection from ground.
