A speaker at an open-air concert emits 600 W of sound power, radiated equally in all directions. A.)What is the intensity of the sound 4.50 m from of the speaker? B.) What sound intensity level would you experience there if you did not have any protection for your ears? c.)Earplugs you can buy in the drugstore have a noise reduction rating of 23 decibels. If you are wearing those earplugs, but your friend Phil is not, how far from the speaker should Phil stand to experience the same loudness as you?

Question1:Speaker A emits sound with an output power of 20 W. Speaker B emits with an output power of 80 W. Suppose you stand some distance, r, from speaker A. How far would you have to stand from speaker B to hear the same loudness of sound? For clarity, only one speaker is playing at a time , so we do not have to think about interference Question2 :You send a transverse pulse down a slinky. A moment later...
A source emits sound waves equally in all directions. The intensity of the waves 2.50 m from the source is 1.90 times 10^-4 W/m^2. Find the power of the source, If the diameter of your eardrum is 8.4 mm, how far from the source do you have to be located so that your ears combined receive 0.42 times 10^-12 J of energy each second?
