If you live next to a highway, you probably hear a lot of noise from the road.

A few ideas for creating a sound barrier between the highway and your back yard:

Build a tall, solid wooden fence and plant vines on it -- this will absorb sound.

Soften up your hardscape -- noise is probably bouncing off of your concrete and flagstone.

Buffer your yard with plants -- deciduous trees and broad leaf plants are the best sound-reflectors.

Plant as densely as possible. You might also consider installing a water feature -- it will add noise, but the sound of trickling water is soothing and might distract you from the highway noise.
