How loud is a cpap machine?

A CPAP machine typically operates at a noise level of about 25 to 30 decibels, which is comparable to a whisper or a quiet room. Some models may be slightly louder, but advancements in technology have made many machines relatively quiet. Most users find the noise unobtrusive, and many report that they adapt to it quickly, often finding it less disruptive than snoring or other sounds.
