How to Create Sound Barriers for Houses Next to Freeways

Have a natural fence put in. A berm, which is a raised strip of earth, is a good option for blocking freeway noise. A berm is an effective and co-friendly sound barrier, although one drawback is that having it constructed might be a bit pricier than a fence. See whether you can cut down on costs by finding surplus dirt, soil or earth from a construction site to use. Another factor to consider is that berms require more space than a fence, so this might not be a good option if the available space around your home is limited.

Plant trees. Though not as effective as fencing, trees are another way to muffle noise. They provide privacy, like fences, and also add beauty to your landscaping. Inquire at a gardening center or plant nursery for which trees would be the best to use. The Leyland cypress grows quickly, it adapts to different climates and is low maintenance. Plus, its large crown grows in a pyramid shape, which helps block noise and wind. If you don’t want to have to wait for your trees to grow, you can spend a little more and purchase mature trees to plant in your yard.

Create background noise. Drastically lessen the noise from the freeway by drowning it out with a sound barrier of competing, more enjoyable and preferred noise. A waterfall can do this. The soothing sound of falling, splashing water not only is relaxing but also will mask traffic racket. Have a pond and waterfall installed in your yard, hang a wall-mounted waterfall, or purchase an ornamental, free-standing waterfall to not only cover traffic noise but also serve as a focal point. Also, hang a large wind chime to produce the pleasant sound of bells when the wind blows.
