“…Despite the higher costs, we must consider not only its higher sound absorption [23] but also its environmental durability [24]. A big plus is also the use of secondary materials, where waste plastics are used for production, mainly from municipal waste [22], demolition waste [25] and waste from the automotive industry (recycled rubber products, technical textiles,…). Thanks to this fact, they can be 100 % recycled again.…”

The authors present the first ideas of contextual design (CD) of noise barriers (NB), which integrates acoustic, architectural, environmental, and economic aspects of a holistic approach to the design of these engineering structures. The paper presents an example of an economic subsystem of CD focused on the economical optimization of NBs with an emphasis on the circular economy. It also demonstrates the significant potential of NBs to improve the architectural visual appearance of built-up areas as essential spatial elements and improve the microclimate of their surroundings. The authors focused on comparing the costs of construction of NB with acoustic elements made of the most used materials in the Slovak Republic: aluminium, chipped cement, transparent NB, and NB made of recycled plastic. The comparisons show that the most cost-effective option is a noise barrier made of recycled plastic. Despite the higher cost, its higher sound absorption and the environmental durability of the acoustic elements are decisive. The use of secondary raw materials is also a significant advantage of CD. Waste plastics, mainly from municipal waste, are used for production, making it possible to recycle 100 % of them again.

“…Implementations similar to noise barriers could support the noise control approach. According to simulations and actual implementations, the use of a noise barrier can affect sound attenuation due to diffraction that is highly dependent on the barrier's height [54,55].…”

Quietness in an urban environment is vital for the well-being of city residents. Nevertheless, the ambiguity in the conceptualization of the terms noise and quietness as urban acoustic planning and design objectives, has resulted in two different approaches: the soundscape approach and the noise control approach. The main purpose of this research is to supplement the existing approaches by proposing a new ecological acoustics approach in order to identify quiet areas in the city of Mytilene (Lesbos Island, North Aegean, Greece). The use of the soundscape approach involved the participation of Mytilene’s residents and the collection of subjective and objective eligibility criteria. By means of Multi-Criteria Decision Making two urban green areas were highlighted as potential quiet areas. For the noise control approach, road noise maps have been created through a commercial noise mapping software, validated by trough measurements. As a result, two areas located in the outskirts of the city were highlighted. Finally, the novel ecological acoustics approach involved acoustic recordings and the extraction of the Composite Urban Quietness Index (CUQI). The outcome of this approach converged with the soundscape approach results. Quietness, as an urban acoustic planning and design goal, could be viewed as an opportunity for ecologically sustainable urban environments.

“…Xiao and coworkers have systematically investigated the engineering properties of concrete with CDW aggregate and filler (Duan et al, 2020a,b;Sun et al, 2021). Moreover, CDW may act as the source materials for geopolymer fabrication (Ulugol et al, 2021a,b), composite manufacturing (Sormunen and Karki, 2019;Clark et al, 2020), and functional materials development for control of environmental noise (Amarilla et al, 2021).…”
