The air moving past the blades gets "chopped" similar to how an old
fashioned siren (rotary) works. There is a substantial sound level
difference on my planer as well when I pull the DC line off.
The bottom line is if you cut back too much on the DC, you'll start having
chip imprints in the wood.

My planer got much quieter when I changed the blades. I hadn't realized
how dull they had gotten.
