When a helicopter is hovering 1450 m directly overhead, anovserver on the ground measures a sound intensity I. Assume thatsound is radiated uniformly from the helicopter and that groundreflections are negligible. How far must the helicopter fly in astraight line parallel to the ground before the observer measures asound intensity of 0.25I?
