Gel or silicone ear plugs
Moldable ear plugs that block noise from the CPAP, mask vent air or a bed partner.
Why it helps
Most current CPAP machines are quiet (ResMed lists sound levels around 33 to 35 dBA for the AirSense 11 in its guide), but the hiss of the mask vent, an air leak or a snoring partner can still keep light sleepers awake. MedlinePlus notes that sounds that make it hard to sleep are worth mentioning to your provider and suggests placing the machine under the bed to limit noise.
How to choose
Moldable silicone or gel plugs sit over the ear canal opening rather than deep inside it, which many side sleepers find comfortable under a mask strap. Foam plugs block more noise but go into the canal. Choose a size and type that does not press on your mask headgear.
Ear plugs can stop you hearing smoke alarms, alarms or a child, so plan for that. A new or louder noise from the machine or mask can be a sign of a leak or fault worth checking rather than masking.
Frequently asked questions
How can I make my CPAP quieter?
Check the mask fit first, since leaks are a common cause of noise. Placing the machine lower than the bed and using ear plugs help many people; tell your provider if a noise persists.
Are gel ear plugs comfortable with a CPAP mask?
Many side sleepers prefer moldable silicone plugs because they sit flat. Check that the plug does not press on a headgear strap.
