Two small speakers emit sound waves of different frequencies equally in all directions. Speaker A has an output of 1.00 mW, and speaker B has an output of 1.50 mW. Determine the sound level (in decibels) at point C in the figure assuming (a) only speaker A emits sound, (b) only speaker B emits sound, and (c) both speakers emit sound.
