The alternative solution of absorptive noise barriers
Original language description
The noise from traffic on roads can unpleasantly affect humans and therefore we must search for means to reduce the intensity of the noise. It can be achieved either by reducing the sound intensity at the source (active measures) or by preventing the transmission of sound by shielding structures (passive measures). In both cases this can be achieved in several ways, which are briefly described in the article. Two main wais are typical for passive measures - either the sound is absorbed by a solid construction and it is subsequently converted to another energy (heat), or the sound is reflected off a monitored area, The combination of these two methods of noise reduction brings modern combined acoustic barriers with higher effiiciency. One of such methodis presented here, but the idea of sound absorption massive structure is replaced by the idea of damped oscillation lightweight construction.
