“…The use of foamed polystyrene aggregates has some effect on noise reduction owing to its lower stiffness, which has a high ability to dissipate energy. Expanded polystyrene granules (EPS) can easily be added in concrete to produce a lightweight concrete of varying density [ 60 ]. EPS are ultra-lightweight aggregates with a density <33 kg/m 3 , non-absorbent, hydrophobic, and closed cell nature [ 97 ].…”

Concrete is the most common building material; therefore, when designing structures, it is obligatory to consider all structural parameters and design characteristics such as acoustic properties. In particular, this is to ensure comfortable living conditions for people in residential premises, including acoustic comfort. Different types of concrete behave differently as a sound conductor; especially dense mixtures are superior sound reflectors, and light ones are sound absorbers. It is found that the level of sound reflection in modified concrete is highly dependent on the type of aggregates, size and distribution of pores, and changes in concrete mix design constituents. The sound absorption of acoustic insulation concrete (AIC) can be improved by forming open pores in concrete matrices by either using a porous aggregate or foam agent. To this end, this article reviews the noise and sound transmission in buildings, types of acoustic insulating materials, and the AIC properties. This literature study also provides a critical review on the type of concretes, the acoustic insulation of buildings and their components, the assessment of sound insulation of structures, as well as synopsizes the research development trends to generate comprehensive insights into the potential applications of AIC as applicable material to mitigate noise pollution for increase productivity, health, and well-being.

“…Gupta et al [289] also proved that the addition of biochar that had been pyrolyzed at 550 • C improved concrete elevated temperature properties far better than fume silica, with a strength increment of up to 20%. Biochar concrete composites showed interesting properties for the sound adsorption across the range of 200-2000 Hz, as reported by several research papers [290,291]. One of the most promising discoveries was comprised of the outputs presented by Kua et al [292].…”

Biochar is the solid residue that is recovered after the thermal cracking of biomasses in an oxygen-free atmosphere. Biochar has been used for many years as a soil amendment and in general soil applications. Nonetheless, biochar is far more than a mere soil amendment. In this review, we report all the non-soil applications of biochar including environmental remediation, energy storage, composites, and catalyst production. We provide a general overview of the recent uses of biochar in material science, thus presenting this cheap and waste-derived material as a high value-added and carbonaceous source.

“…It was determined that the use of superfine aggregate type can decrease sound absorption, the use of lightweight aggregate type can improve sound absorption and the use of polypropylene fiber additive can enhance sound absorption. In the research of Oancea et al [ 106 ], the sound absorption coefficient of sustainable concrete with different waste replacements are investigated, and five different types of sustainable concrete, which consist of polystyrene granules, polyethylene terephthalate granules, corn cob granules shredded sunflower stalk, and balls made of sheep wool, were analyzed. Oancea et al [ 106 ] stated that each of the sustainable concrete has sound absorption coefficients higher than those of the conventional concrete and in the cities, and these types of materials can be used as a sustainable solution for both waste and noise problems.…”

Environmental noise control is necessary for human health and auditory comfort conditions. In this respect, it is required that industrial noise should be kept under control and healthy living spaces should be obtained in residential areas. This paper aims to explain industrial noise control at urban and building scales. In this study, the strategic noise mapping process related to industrial activities in a line with the Environmental Noise Directive (END) was clarified. Besides this, what type of factors are effective in the industrial noise mapping process were defined, and important basic parameters, which are essential in the industrial noise mapping, were detailed. The preparation of the industrial noise mapping process was explained in detail. It was mentioned that the regions exposed to excessive noise should be defined according to the strategic noise map and improvement plans should be performed. Improvement methods that reduce excessive noise in living spaces are clarified and it was explained how the improvement of environmental quality can be acquired. In this regard, this paper gives information on industrial noise mapping and industrial noise control at the urban scale.
