You can increase the height of the wall or try to diffuse the diffraction to reduce the noise. This is only a partial solution, since the diffraction property of sound waves still allows some noise to go around the wall or fence. You can add a wall in your back yard to try to block noise from reaching your house. You can also build a higher wall, but that may not be practical. In this way, the wall stops much of the noise, while the shrub diffuses the other part of the noise. One example is placing shrubs that go above the top of the wall. Since the diffraction is caused at the edge of the wall, placing objects or material above that edge can help to diffuse the diffraction.

This is a form of diffraction of the sound waves.Įdge diffracts the noise Possible solutions When sound waves reach the edge of an obstacle, that edge causes waves to curve as if the edge was a source of the sound. The problem is that some noise still seems to reach your back yard, due to the diffraction property of sound. A common way to do that is to build a tall fence or wall in an attempt to block out the sound and noise.Ī solid wall or fence can reflect some sound waves and absorb other waves, such that very little noise gets through the wall.

If your house is near a busy freeway, or there is some other source of noise reaching your home, you might want to find a way to block out that noise.
