Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Review Description
Urban sustainability issues in buildings have become more prominent in waste recycling and noise control studies. This work aimed to produce and characterize the composition of polyurethane foam residues and recycled plasterboard sheet cores for acoustic absorption. The mechanical properties of ABNT NBR 16831 (2020) for transverse direction 160 N and longitudinal direction 400 N have been followed. The morphology has a porosity of 47.45% due to the large number of small open pores with relevant sound absorption coefficients in all frequencies compared to the original waste and the commercially-available mineral lining. The experiment resulted in a mechanical energy absorption composite at frequencies 250, 500, 1000, and 2000 Hz with the potential to improve acoustic comfort.
