A:Answer I'm sensitive to noise pollution, (don't get me started on leaf blowers!)
One's tolerance of noise is, of course, subjective.
My assessment:
Low speed is barely audible.
Medium speed emits a gentle, soothing white sound. The white sound masks background noise, therefore, I enable it when meditating and sleeping.
High speed is considerably more audible, but when compared to many other fans is not bad. I never need the high speed.
I hope this helps you.
