My parents and siblings aren't musicians, and yes, my practice is really really irritating to them, so I try my best to be considerate and not practise during people's favourite tv shows, etc.
Because I also work and go to uni, I try to get to work really early, then I can leave work early and come home to do my practice before other people get home. Or else I do my practice in the morning, when everyone is too hectic to care, and I go to work late.
My bf, however, loves my practice. He's a mathematician, and an academic, and he somehow finds he thinks better if I'm making a ridiculous amount of noise. So he likes doing his reading and thinking in the same room where I'm practising. In fact, he used to ask me to do my practice so he can do some thinking!!!
