That loud, jarring *BANG* when the wind catches your metal trash can lid is enough to startle anyone. It's a common nuisance, but thankfully, preventing it is usually straightforward and inexpensive. The core issue is the hollow, resonant nature of the metal and the loose-fitting lid. Here are several practical solutions to restore peace and quiet to your outdoor space.
First, address the inside. Line the bottom of the can with an old towel, a piece of carpet, or a rubber mat. This absorbs impact when bags are tossed in and dampens the can's natural resonance. For extra sound dampening, you can glue or stick rubber pads (like furniture pads) to the inside walls.
Next, secure the lid. This is often the main culprit. A simple bungee cord hooked from the handle to the can's side or a sturdy elastic strap can hold the lid firmly in place. For a permanent fix, consider installing lid locks or latch kits designed for trash cans. If the lid just sits loosely, adding self-adhesive foam weatherstripping around the rim creates a tighter, quieter seal.
Weight is your friend. Place a heavy brick or a large, smooth rock inside the bottom of the can (under your liner bag). This makes the entire unit heavier and less likely to be rocked or tipped by the wind, which is a primary cause of banging.
Finally, consider the can's placement. Moving it to a more sheltered spot, like against a fence or wall, can block much of the wind. Placing it on a soft surface, such as an area with grass or mulch, instead of concrete, can also muffle any incidental movement sounds.
By combining a few of these tips—like adding a bottom liner and securing the lid with a bungee cord—you can effectively eliminate that disruptive banging noise for good.
