Evergreen shrubs make the best plants for noise because they provide year-round noise reduction. Broadleaf evergreens are more effective than narrow-leaf plants and conifers. Choose trees and shrubs with dense branches that reach all the way to the ground.Click to see full answer. Keeping this in consideration, what plants make good sound barriers?For year-round noise reduction, plant a mix of evergreens such as arborvitaes, spruces, pines and hollies. To be effective sound barriers, these trees must have foliage that reaches to the ground. Deciduous plants are also effective for noise abatement, but only when foliage is present.Also, how much can trees reduce road noise? North Carolina State University estimates that a well-placed tree can reduce noise as much as 40 percent, adding that a barrier 45 feet high and 100 feet long can reduce it as much as 50 percent. Similarly, you may ask, do trees help reduce noise? Trees that not only absorb carbon dioxide, give shade, avoid soil erosion it also helps to reduce sound pollution. One way to reduce sound pollution is sound absorption. Tree parts such as thick branches, leaves and wood are effectively absorb sound. So it reduce sound.Does bamboo make a good sound barrier?Living bamboo can be an excellent choice, both as a noise barrier and as a privacy screen. The ideal way to buffer street sounds is to interpose a mass of sound-absorbent material between your home and the street. A bamboo privacy hedge can form just such a mass, because its canes grow together so densely, by nature.
