I measured the following at the lowest level:
5 cm from fan outlet, 60db max. value / 50db average
50 cm from fan outlet, 30db Max. value/ 25db average

I chose this dehumidifier because of its comparatively low power consumption. The volume is ok for me. The noise of the fan is not disturbing at a distance.

I can't say in DB. But I find that the unit runs at a reasonable volume. It also works well and quickly. I am satisfied with it.
