“…The minimal values of the acoustic characteristics for the analyzed types of panels are reported in [51,53,73]. It should be noted that the acoustic performance of the panels strongly depends not only on their materials but also on the thickness of their absorbing layer, their texture, and the cross-sections of their surfaces [89] (flat, trapezoid, or undulating (low or high waves)).…”

Despite the long-term experience in the application of noise walls, the uncertainty in wall panel service life efficiency is almost equal between panels built from established and new materials, which are—because of the desire to increase the sustainability of noise walls—developing at an ever-faster pace. The presented meta-analysis of data collected during a systematic review of concrete, metal, and wood panels’ acoustic and non-acoustic characteristics, long term performance, and cradle-to-gate sustainability aims to reduce this uncertainty and support the process of noise wall design and management by shifting the emphasis in decision making from construction costs to the long-term sustainability of the road traffic noise mitigation project. The multi-criterial analysis showed that when choosing a panel, preference should be given to those using lightweight concrete materials. A further comprehensive cradle-to-grave assessment of lightweight concrete panels with expanded clay and recycled tire rubber aggregates, which was performed to fill a knowledge gap observed in the literature and identify opportunities for the improvement of lightweight concrete sustainability, showed that the main environmental impacts of these panels are due to their production processes and that the way to reduce such impacts is to use panels made with aggregates from secondary raw materials.

“…According to the findings of this study and practical experience, the length of the protective noise barrier should be longer compared to the length of the existing roadside facilities. The analysis and measuring the noise on the A2 motorway (E-65) "Majka Teresa" section: Skopje -Tetovo When choosing the type of noise barrier, it is certainly recommended to perform optimization by acoustic, technological and economic features in order to obtain the optimum sound barrier [24].…”

The analysis and measuring the noise on the A2 motorway (E-65) "Mother Teresa" section: Skopje -Tetovo Traffic noise measurements on the Skopje -Tetovo Section of the Mother Teresa A2 Motorway in the Republic of Macedonia are presented in the paper. The first measurement was conducted in 2003 immediately after the motorway was opened to traffic, while the second one was conducted in 2014. Noise levels were estimated according to two calculation methods. After it was established that noise levels exceeded the legally allowed limits, appropriate protection measures were proposed and adequate conclusions for solving the noise problem on the section under study were adopted.

Nowadays, each individual is exposed to noise on a daily basis, and noise is often referred as in literature as a plague of modern society. Noise pollution is often overlooked when compared to other environmental pollutions (e.g. air, water, soil pollution). However, same as the all aforementioned pollutions, noise exposure has an accumulating character, meaning that the harmful effect of noise is detected only after a long period of time. Long exposure to noise pollution can be displayed as a bad mood, fatigue, insomnia, headache and loss of concentration, which causes reduced work ability and ultimately permanent hearing impairment. The goal of this chapter is to present two different approaches (traditional and contemporary) in noise reductions. The aim of both approaches is to link objective and subjective acoustic parameters, in order to plan future urban infrastructures while keeping in mind the existing acoustic environments, and to create and implement new solutions that will design, preserve and improve acoustic environments. Thus, we can conclude this chapter will be oriented towards human health and overall quality of life in terms of noise reduction.
