It's probably a loose cover - the grill housing where the light bulbs are. This model is attached by torsion springs and they allow it to vibrate.
You can try adjusting the cover, but if it keeps happening, you'll probably want a different fan.

Panasonic makes a good bathroom fan.

Depends on what you need.

We have a very old Nutone fan, and the thing sounds like a helicopter.

These threads always lead to the conclusion that you have two main choices for bath fans. Units that have the fan motor in the housing (like the Nutone or Panasonic fans already mentioned), or quiet inline fans that are quieter and have the advantage that they can be mounted further away from the bathroom space in the attic. The Panasonic fan owners like them, and I believe they are good due to the consistent endorsements here. I am from the inline fan camp and retrofitted (by removing the fan) my old enclosure to use a Fantech inline fan kit and avoided any unnecessary drywall work by doing so. Simple.

I used this inline fan kit to retrofit my old bath fan box:

I put a new motor in my master bath and it runs better then new.

Smooth and quiet.

Go figure.

Maybe $25 when I did it.

Nutone can be weird units. Once a year I take the blower unit out of the housing, blow it out with an air compressor, wipe everything down and try to lube the shaft. Otherwise is sounds like a helicopter when dust buildup get the fan out of balance.

This unit is brand new so it should be no issue..

It says it's rated at 1.0 Sones it's pretty loud if you ask me.. I'd hate to hear what a 5.0 sones sounds like

Try to move the shaft front or back. The replacement motor I have in mine got crazy loud for no reason shortly after I installed it. I found the shaft had about 1/8" of play and if you move it one way or the other is would quiet down. I did that one time and it never came back.

Might be a faulty unit. We just installed one of those 80CFM's and I can barely hear it running.

I recently remodeled a bathroom and installed a Delta Electronics exhaust fan. It's a bit on the pricey side but it is remarkably quiet and does a great job at moving air. For my application I used a 130 CFM model but if you are looking for one that's only 80 CFM, consider this one.

My previous residence had one and it sounded like an Apache gunship.

I'd check the vent duct to make sure it isn't clogged anywhere.

No kinks? Louvers opening correctly? Damper in fan opening correctly?

Do I have to pull the housing down to check the damper? Maybe that's where I hear the rattle from?

Not sure what it takes on your fan to get to the damper but I would recommend checking it.

It is usually the fan being out of balance on these units that generates the vibration. Because the fan blades are usually made of plastic the fan blades cannot be easily reshaped to attempt to quiet the vibrations.
The Panasonic ones use a quieter technology for the blades (many computer whisper fans are Panasonic).

Diagrams are in the PDF spec sheet and installation manual at this link:

»www.nutone.com/products/product/···overview

Based upon the diagram, it looks like the damper is enclosed in plastic housing that clips to the exterior surface of the metal frame. If the o.p. has access from the attic, it will be be easy to pop it off and check it. If no attic access, then it might be possible to see from the interior of the box, but I can't tell from the diagrams.

Did you consider calling the NuTone tech support line? They can probably help you with whatever problem that you are having with a relatively new fan.
