Taking the concept of low noise further is the Whisper Quiet enhancement which allows the device to work at sound levels as low as 26.6db. Besides, this gadget from ResMed is a doctor’s delight as patients and their family members cannot change the pressure levels without hands-on experience. However, this attribute might be restrictive if you are considering a machine for treating different levels of OSA within the same household.
