How loud is a CPAP Machine?
Most manufacturers list the noise output level of a standard CPAP machine at 30 decibels. Formally, 30 decibels is considered “almost total silence”. The sound a machine outputs does vary on the make and model, and smaller does not always mean louder. If looking to purchase one machine over another, I would suggest looking at various CPAP chat rooms and blogs to see what users have to say.
