Question 3: You measure the sound level of the call of a single tree frog to be 55 dB. a) If the single tree frog is joined by 29 other tree frogs so that there are 30 in total and they are all about the same distance away as the first frog, what sound level (in dB) would you measure? Assume all the frogs emit identical calls. ignore interference effects. b) How much farther away would you have to move (how many times the original distance) for the sound level of the 30 frogs to be 55 dB
