other guys recommended here. However, alignment won't fix the noise, only to stop getting worse. You would have to replace the tires to get rid of the noise. Since your car ran into a hole, it's a little hard to say if the tires are the root cause.
My assumption was that the noise was getting loud over time (was ok before right after the accident, right). Was that noise like beating a drum? (rubber noise).
If your tires got enough miles already, maybe it's worth to replace them for trouble shooting.
