Fabric Door SweepsĮxpected Sound Reduction of 0-2 dB: Fabric door sweeps, sometimes called draft stoppers, may seem like they would reduce noise transmission between rooms, but they’re actually quite bad at that. Door sweeps are much better for thermal insulation and draft reduction between rooms. Door sweeps block sound to a minimal level, the best you will get is up to 4dB noise reduction. Effective soundproofing just requires a greater attention to detail, which is why insulating door sweeps, while better than nothing at all, aren’t great at soundproofing. A small glass window in a solid brick wall, for example, can reduce the noise blocking effectiveness of the wall by nearly half. Even the tiniest gaps in a door, window, or wall can allow sound to escape as though there were nothing in the way at all. The larger the leak, the faster the water rushes through. If you don’t have a perfect seal around the bottom and sides of the pool, water leaks out through the gaps, cracks, and seams. We like to think of soundproofing a room like building a pool. So for our purposes, soundproofing is a lot like waterproofing. Sound is a wave, and it tends to behave more like water in that it finds a weak point and “leaks” its way through the gap. If the air isn’t moving from one room to another, neither is the heat. That’s why standard door sweeps are so effective at insulating, because while they may not form a perfectly air-tight seal, it’s enough to reduce the movement of air to a less noticeable level. For example, in a large bedroom, a tiny gap in a window frame, say less than the width of a human hair, won’t make a noticeable difference in the room’s temperature as a whole, even on a very cold day. It takes a pretty significant volume of air to change the temperature of a room. We’ll explain why standard door sweeps aren’t great at soundproofing and offer some alternatives that block sound more effectively, including the best soundproof door sweep, our Sound Lock Door Seal Kit. This article will cover the different types of door sweeps, including their uses and benefits. For homeowners, apartment dwellers, and business owners who have to live with an imperfect door seal, there are DIY solutions to turn down the volume and minimize drafts. In a perfectly soundproofed world, all doors would be solid core and form a perfect seal against the frame and the floor below, but we don’t live in a perfect world. Ready to start your project?
