Find number of minimum intensities of sound heard by a man while walking towards the speaker and finding the positions of the man when he heard minimum intensities of sound.

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

A) How numerous times he'll here a min in sound intensity?

B) How far from the pole at these moments?

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