OSA health risks aside, we all know that disturbing our bed partners sleep quality with noise can also be hazardous to our health! The transition from loud offensive snoring in the bedroom to a semi-silent CPAP machine is a great step forward but how do we choose the right device for the balance between cost, portability & noise level?
We are commonly asked, which CPAP machines are the quietest to use and there are many factors that can affect the "bedroom" noise level. For example, the decibel rating of a CPAP machine is one way however a CPAP machine with a lower decibel rating might sound louder in the bedroom if it has a higher pitch.
Another factor to consider is that some devices are quieter at the machine-end but louder through the exhalation port on the mask because the noise is conducted through the tube. Some machines emit the same noise level at one pressure, and vastly different noise levels at other pressures. Others are noisier on inhale and silent on exhale meaning that the inconsistency is more annoying than a constant hum.
