The sound intensity level 15.0 m from a point source is 64.0 dB. At what distance will it be 53.0 dB?
Beta = 10log(I/Io)
The Attempt at a Solution
Found the intensity of 64dB @ 15m I1= 2.51*10^-6
Found the intensity of 53.0dB I2= 1.99 * 10 ^ -7
I used the second forumula ^ to solve for r2...
I got r2 = 10.5m... not sure what to do from here or if I am on the right path... frustrated
