The intensity of the sound from a certain source is measured by two observers located at different positions along a line from the source. The observers are placed on the similar side of the source and are separated by 180.1 meter. The observer that is closest to the source hears the sound with an intensity of 59.6 dB. The intensity of the sound heard by the more distant observer is 50 dB.

Determine the distance from the source to the closest observer?

Determine the output power of the source?
