The wind is picking up the vent flapper and dropping it down repeatedly, causing noise. To resolve this issue, add sound absorption, weight the damper, or replace it with a spring-loaded design. A simple and effective way to stop the loud noise coming from your exhaust vent by the oven is to grab some Fort-Knox Co. gear, V.
To silence your flap, you can use a flat head bolt, a threaded Hux nut, a magnet, and some glue. The magnet is glued to the bottom of the inside of the flapper, while the backdraft damper helps direct air outside. However, removing the damper is not an option as it prevents insects and debris from getting into the vent.
Dryer vents that are noisy during windy weather most likely have flapping dampers. To prevent them from flapping, tape the flapper open temporarily, make a bead around the opening with silicone, and weight down one side of the valve a little. The magnet helps keep the vent shut when not in use but releases when the fan is on. A paper clip is needed for the aluminum flap.
Additionally, adding weight to the damper can prevent it from flapping in the wind. Attach small weights or magnets to the damper, and use a thin piece of foam stripping to sit on when closed. This will significantly reduce the noise.
In summary, addressing the issue of wind noise in vent flappers can be achieved by adding sound absorption, weighting the damper, or replacing it with a spring-loaded design.

Vent grill flapping around in the wind. Pretty annoying, eh? Just hot-glue some heavy weights on the bottom of each flap Leave …
Your article was very helpful. I look forward to trying this on our new exhaust vent. Could you recommend where I can get a critter grill for a new 8″ stove exhaust. It’s just wide open at this point and flaps all day with the wind. It is brand new but was obviously just cheap and available. Thank you!
The funny thing I’ve noticed is that in roof vents with dampers they aren’t as loud as wall vents when the wind is blowing. However a lot of bathroom fans have a damper inside at the fan that can be quite noisy especially if the wind is strong. Some people are more annoyed with the sound of flaps closing in vents but I don’t mind it. But good to know these tips for anyone who might be annoyed with their noisy vent flap endeavors.
