Abstract
Noise pollution caused by heavy traffic of road motor influences in a manner becoming more marked, the quality of life. Understand and study the noise’s nature and quantify the entity, finding out the right solutions to avoid the impact on the population is not so easy like conceive a standard survey, but is necessary to entrust the study to professional peoples, able to identify the entity and the type of noise and subsequently, study the right solution to solve each specific problem through suitable projects. Street absorbing panels result from such research.(1,2,8,11)
Fibers of many types, including some natural fibers, have been used widely for architectural applications in structural and non structural assemblies. The mechanical proprieties, along with relatively low cost and ease of handling indicate good possibilities for their use in composites. In terms of cost, flax fiber rates among the more expensive of the natural fibers, often exceeding that of e-glass.(3)
It is necessary to optimize the material formulation, the workability for different application cases. This remark introduces the multi-material notion or the multi-functional structure notion, where the association of different components permits to increase the performance. .
The most common materials in the manufacture of street soundproofing panels are metal, wood, ceramics, concrete, reinforced cement, glass laminated, polimetilacrilat, polycarbonate and plastic.(10)
