How to quiet the dryer vent from the outside

dryer

I have a Whirlpool electric clothes dryer and it is under 5 years old.
When it is drying it makes a "whirling sound" that is especially loud from the outside where it is vented. My neighbor is constantly complaining about it. We shoved a large rock up in the vent from the outside and that helped a lot, but the clothes did not dry properly as they should have on the normal setting with the normal amount of clothes that I always dry.

Absolutely do not block the vent - this could cause a fire!

The first thing to check is that your duct is free of lint and other debris. If it is a plastic duct then I wouldn't even bother cleaning it and instead would replace it with a metal one. A rigid duct line is probably better than a flexible one but is a bit more difficult to work with.

Check for any unnecessary bends or kinks in the line - the straighter the better as bends restrict the airflow and result in additional noise. If it is a collapsible/flexible duct, make sure it is fully extended and trim off any excess ducting.

If possible you might consider relocating the exhaust further away from you neighbor.
