I am concepting out an 80 foot sound barrier to run along my property approx 15 feet above a busy road, and wondering if any one who has built a sound barrier knows anything about the company connected to the link above?

Hey Ana.

Still digging for an answer. Below are a few links that should help you.

The most important thing I have learned (other than the positioning of the source noise and your ears and the sound barrier in between) is that any material you use works, as long as the density of it is equal or above 20kg per meter cubic, sounds cryptic I know, but is explained better in one of the attached links.

(this is for the clear sound barrier option, best company I have found so far. Just about to connect with them for contractors in Southern California USA)

http://www.fhwa.dot.gov/environment/noise/5.htm
(positive/negatives of different materials, via USA gov study.


http://www.fhwa.dot.gov/environment/noise/3.htm#3.5.2

(See 3.4 for sound barrier defraction info, very good, bottom line, high frequencies, when deflected off a wall, continue up, low, bend down. High = whind noise in wheels of cars, Low = rumble of rubber)

http://www.fhwa.dot.gov/environment/keepdown.htm
(great USA gov article about basics of sound barriers. See "Type of material" for 20kg density info, tho entire article is really helpful)

http://www.simetric.co.uk/si_wood.htm
(info for wood density, good against the 20kg info)

Hope this helps. Good luck. And remember, just 5dbs of noise reduction is pretty significant and 10dbs, say 70 dbs (heavy traffic) to 60dbs (light traffic) is excellent. - AB
