Homework Statement
You are 10m away from a sound source. If you want the intensity in DB to double, you must move to a distance...?
Homework Equations
Idb = 10log(I/I0)
I is proportional to 1/r^2
The Attempt at a Solution
I know the answer is 1m and I know that in order to make the sound louder, you need to get closer
Not sure how to get 1m though
Thanks
