Unless there’s a leak (and there shouldn’t be) CPAPs are much quieter than you think they are. The only time I even notice mine (Resmed with P10 nasal pillows) is when using it from a battery during a power outage when everything is dead quiet. If you have any kind of background noise (fan hum, AC, air purifier, living near a freeway) you probably won’t even notice it.
