| Abstract: |
Along side with the fast infrastructure development such as highways, roads and railroad tracks there is increasing stress on protection against noise produced by these line sources. In general it seems to be the most efficient way to reduce noise by building anti-noise walls along line sources of traffic noise. Anti-noise walls absorb the noise and protect from distribution to surrounding environment. The paper describes possibilities of use of waste from production of technical hemp for production of anti-noise walls with high level of sound absorption. Advantages of these walls are not only good acoustic properties but also lower price and utilization of environmental friendly material. The used technical hemp is easily renewable material source; technical hemp can be substituted by another similar material typical for the particular area or more easily accessible. |
