I keep a television on near my birds, even when I'm away at work, at moderate volume. From the time they are little pips on, they are accustomed to having this big old shop vac roaring through ~ and they remain unflappable.

I do most of my cleaning and feeding when they are fast asleep in the morning when all the lights are on ~ and they seem to sleep through that as well. It makes cleaning the cages easier as I can leave all the doors open, knowing that they are fast asleep.
Do others acclimatize their birds to noise as well? What types of noises do you use? Soft Mozart? Rap? Any special television channel? Do you find that your birds can sleep through your noise as well?
Thanks.
