If you are always reading at home (and therefore tips like try reading in the library aren't relevant), then give reading a go with the TV on low in the background when people are asleep/out as an initial experiment and go from there. Essentially, you want to expose yourself to a bit more noise as time goes on. Effectively white noise but not as 'loud' and with a bit of difference in the sound. Work your way towards regular white noise.

Another idea might be (and this I'm basing on your wanting to read but doing other things in your free time instead) to start with very short books - a novelette or short story collection or, at most, a novella. They may not be the books you're currently interested in reading but may help to form a habit and will give you that 'reward' of finishing a book quickly which could help all by itself, giving you that feeling that you've done it once, now you can do it again.

This. It providing the book in a different format may also do wonders because it's then not the same as a university book which is on paper/screen.

This. It doesn't 'cure' it, but it helps a whole lot.
