Reduce Outdoor Noise with a Sound Blocking Fence As it gets warmer and people emerge from their winter hibernation into the summer sun, noise always becomes an issue. This is especially true when it comes to backyard noise in residential neighborhoods. To solve this problem, you can reduce outdoor noise with a sound blocking fence. 

The source of the noise can be cookouts, pool pumps, air conditioning units, young children, or number of other things.

Regardless of whether you’re the one making the noise or the one trying to enjoy some quiet time one yard over, we recommend a sound blocking fence.  Also referred to as a soundproof fence, these sound barriers absorb noise and can also block it from transferring between properties.

Specifically, our most commonly used acoustical solution, and the most affordable product for residential sound blocking fences is our AudioSeal™ Exterior-Grade Acoustical Blankets.  Sold by the individual blanket or roll in standard sizes, these products make retrofits to existing structures easy and cost-effective. 

Please be sure to verify your structure will comply with local building codes, ordinances, or homeowners’ association.

Case Studies:

Reduce Outdoor Noise with a Sound Blocking Fence This particular person lived near Philadelphia and installed central air conditioning. Their neighbors complained to the city about the noise levels (notice how close the houses are). She was told she couldn’t use her AC until she got the noise levels below the city ordinance. After discussions she decided to install a stockade fence and line it with AQFA-10 EXT sound absorbing blankets. She expedited the order since it was the week before Memorial Day. After installation of the AQFA-10 EXT material, the AC noise was well under the city ordinance noise limits. She stayed cool and comfortable all summer long!

The next story involves a bank next to a church. The bank installed a new AC system and it was too loud for the church. They weren’t required by law to do anything about the noise, but the business wanted to be a good neighbor. They installed ABBC-13 EXT blankets in the 2″ thick version (this model comes in 1″ or 2″ thicknesses, with an option for 2lb psf instead of 1lb for the 2″) on the side of the bank building and reduced the noise level to an acceptable level for the church. Even though these panels aren’t supported by a fence, the acoustical treatment is just as effective. During the summer the church was able to open the windows without hearing a constant hum from the bank’s AC unit.

Both of these stories happen to be specifically about outdoor HVAC noise blocking, but this solution would work to reduce outdoor noise of any kind. If the barrier will block the line of sight between you and noise source, it will block the sound as well.
