I can put up with soft noises, or very repetitive/constant (like running water or a tapping sound) noises of moderate sound level. If people are talking I can't sleep, so I've never been able to sleep when I can hear a TV, radio or music.
I have trouble sleeping when there's a lot of light, too, but I think that has more to do with my internal clock telling me that it's not time for sleeping.
