How effective are highway sound barriers?

Noise barriers are solid obstructions built between the highway and the homes along a highway. They do not completely block all noise they only reduce overall noise levels. Effective noise barriers typically reduce noise levels by 5 to 10 decibels (dB), cutting the loudness of traffic noise by as much as one half.Click to see…

They do not completely block all noise they only reduce overall noise levels. Effective noise barriers typically reduce noise levels by 5 to 10 decibels (dB), cutting the loudness of traffic noise by as much as one half.Additionally, how can you make an effective noise barrier? 4.16 To be effective, a barrier must block the “line of sight” between the highest point of a noise source and the highest part of a receiver. To be most effective, a barrier must be long and continuous to prevent sounds from passing around the ends. It must also be solid, with few, if any, holes, cracks or openings. Also to know is, who pays for sound barriers on highways? And anytime a highway is widened, like they’re doing on 128 in Westwood, the state is mandated by the federal government to do something. It’s called a “Type 1” project. The feds pay 80-percent, and the state has to pick up the other 20-percent. Usually a barrier costs about $4 million per mile.How do you drown a highway noise? Steps Build a fence. Building a fence around your yard can help block out any unwanted noises. Place a fountain near your house. Running water does two things: drown out other noise and create a peaceful environment. Shape hedges around your yard. Hedges are an attractive way to reduce traffic noise.
