You can sleep within a couple of feet from the small Snomaster, Even if you are awake trying to get to sleep they run that quite getting to sleep is not a problem, I am a light sleeper and the slightest noise wakes me, Other fridges really annoy me when it comes to getting asleep but not the 35L Snomaster, nothing comes close in that respect when it comes to the lack of noise.Can you sleep near a 12v without getting woken up by a cycling compressor?
This depends on the person. Some people can sleep through almost everything, while a drop of a pin wakes up the next person. Mothers can here a baby roll over in their crib in the next room and sleep through a barking dog outside of their window.
Living on a ship with with constant noise around you, many people adjust to the noise.
