What is the power output of the source

Reference no: EM13553165

The intensity of the sound from a certain source is measured at two points along a line from the source. The points are separated by 17.2 m, the sound level is 70.00 dB at the first point and 56.13 dB at the second point.

a) How far is the source from the first point?
b) What is the power output of the source?
