My husband just started using a BiPAP last week and we've had to sleep in separate rooms because of the noise of the machine. He did a 1 week test with a machine that recorded his breathing and that machine was silent. This one sounds like a tiny turbo with each breath--in, out, in, out.... I think I'd be OK with a solid white noise, but the in and out keeps me awake, or wakes me if I've managed to fall asleep. Using a loud white noise generator to drown out the machine might work, but I cherish the quiet nights with windows open listening to crickets when I wake up at 2 AM.

Has anyone had experience using sound insulation material around the machine?
