When it comes to problems of sound, there are three paths you can take in solving the issue:
1.) Address the problem at its source (where is the sound coming from. We'll say we're dealig with a loud sound. . .can the source be eliminated?)
2.) Address the transfer of sound between the source and the receiver (put up a soundproof barrier, maybe)
3.) Address the problem at the receiving end (Make the people who have to listen to the loud sound wear earplugs)
While this sort of a structure can't be applied in every situation, I've found it can be a useful tool in helping solve a range of problems.
1.) Move somewhere warmer
2.) Invest in warmer clothes
3.) Teach yourself not to be bothered by the cold

3.) Change the way you think about them.

Can't concentrate on homework?
1.) Change the homework . . .work on something else
