I find that some peaceful music without any words can be really helpful when I am trying to study. I like to listen to ambient CDs by composers like Brian Eno, Steve Halpern, or Laraaji. These are soothing and help me focus without distracting me with lyrics.
This Brian Eno album, Music for Airports, for example, is one that I find particularly good:
You may also find classical music to be a good choice. Many people like to listen to Mozart because they think it makes them smarter. This isn't actually true, but it is still a good choice. Background music also helps you drown out any distracting noises, like traffic or people talking in the next room.
Making sure that you have a routine that you stick to can also really help. If you get in the habit of studying at a certain time and place, it will eventually be a lot easier to get down to work. Be sure that your study space is free of distractions. This means no TV, turn off your tablet or smartphone, and don't check your e-mail every few minutes.
Be sure that anyone that you live with knows not to bother you when you are trying to study. Your studies are important, so don't be afraid to say no to people when you are busy. They need to respect your space and your needs so that you can get your work done.
