How noisy will my sleep apnea machine be?

Treatment should not be louder than a whisper - after all, you're supposed to be sleeping. If your equipment is making loud noises, some of the parts might not be connected properly, causing air to escape (or 'leak' out). You can usually work out where the noise or leak is coming from: the machine, humidifier, tube or mask.

Check that everything is connected properly, and then see if you notice a change in noise.
