Landscaping Ideas to Cut Down on Noise

Hedges

• Dense hedges can reduce street-level noises because they create a barrier that deflects and disguises some of the sound. Hedges may do more to lower noise levels psychologically than physically. According to "This Old House" magazine, homeowners perceive noise differently based on whether they look directly at the source of the sound or if they are looking at hedges and trees. Carry this theme of psychoacoustics further and use fragrant foliage to reinforce the presence of the plants by using another of your senses to remind you that something stands between you and street noises.

Water

• Water splashing in a fountain can help to mask other sounds and alter whether you perceive those sounds as intrusive or as forgettable background noise. The sound level you can generate from a fountain varies according to the diameter and depth of the vessel as well as the speed and volume of water. Water fountains will also sound different based on whether they are in a walled courtyard or out in an open garden. The closer you can position yourself to the fountain and away from the source of the offending noise, the better the fountain will be able to block the outside noise.

Berms

• A berm is a hill or mound of earth that you build up to divert wind and sound. Berms are organic alternatives to high brick or stone walls. The keys to success with berms as a sound barrier are location and landscaping. The specific height and placement of the berm depends on the source of the noise and the layout of the property. Homeowners should take advantage of the services of sound engineers to help them decide where to place the berm. Adding plants and shrubs helps the berm to blend into its surroundings.

You

• Reduce the amount of noise that you produce on your property by choosing grass lawns over tile or concrete courtyards. Use soft, sound-absorbing materials, such as packed dirt and rubber pavers, instead of hard, sound-reflecting materials, such as stone or tile for pathways. Plant flowers and berries to attract birds that can fill the air with natural whistles and songs. Position gathering spots, such as swimming pools and decks, behind berms or thick walls.
