calmly ranted:

Check the mounting. Are the screws evenly and gently tightened? You
might try loosening them a skoach when the fan's running, if you can.
Then slowly ease them back in. I had a real noisy muffin fan in a
Miller welder that got quiet when I tightened the screws.

0.5 to 2.0 sones is considered quiet. He bought a 6.5 sone fan.

listings only up to FIVE sones. g

Exchange it for a quieter style or learn to live with it, Jeridiah.

P.S: Shy people LOVE noisy bathroom fans.

P.P.S: Venting stairway air to the attic? Have you looked into
using a thermostatically controlled louvre in the ceiling instead
of a fan?

For reference - fan is 8" with a baffle rated at 180CFM and 6.5
