TL;DR: In this article, the use of a numerical time-domain simulation based on the finite-difference timedomain approximation for studying low and middle-frequency room acoustic problems is described, and an interesting approach lies in using the FDTD simulation to adapt a digital filter to represent the acoustical transfer function from source to observer.

TL;DR: Soundscape research represents a paradigm shift from noise control policies towards a new multidisciplinary approach as it involves not only physical measurements but also the cooperation of humanity and social sciences to account for the diversity of soundscapes across countries and cultures, with more focus on how people actually experience the acoustic environments; and it considers environmental sounds as a "resource" rather than a "waste" as mentioned in this paper.

TL;DR: In this paper, the influence of a green roof on the facade noise load was investigated numerically for road traffic at close distance for non-directly exposed (parts of) facades and showed that a sufficient green roof area is needed to obtain significant reductions in total A-weighted road traffic noise level.

TL;DR: In this article, a large set of black carbon (BC) measurements was collected in Antwerp, Belgium, using a bicycle equipped with a portable BC monitor (micro-aethalometer).

TL;DR: In this article, a vegetation belt of limited depth (15m) containing periodically arranged trees along a road is numerically assessed by means of 3D finite-difference time-domain (FDTD) calculations.
