Find sound output of man whose loud speech produces pressure

a) The noise level from a sewing machine was found to be 96dB (linear) at a distance of 1 metre. Find the sound power of the machine in picowatts. (Assume it is in free field.) b) A lighthouse has a foghorn with a sound power output of 100W. If it radiates over a quarter of a sphere, at what distance would the level be 100dB? c) Calculate the sound output of a man whose loud speech produces a sound pressure level of 80dB(C) at a distance of 1 metre.
