All my hamsters are in my lounge, so they have to manage with the tv, music and conversation when I have guest or I'm talking to myself, lol.
I make sure that the volume of the tv and any music is never too loud but I haven't noticed that any of the fluffs are bothered. They all have their different routines, regardless of what I am doing. They aren't even bothered when Henry the budgie comes to stay and chirps etc all day.
