Evaluating annoyance mitigation in the screening of train-induced noise and ground vibrations using a single-leaf traffic barrier

External sources such as traffic and construction work cause noise vibration in nearby buildings, potentially annoying human residents. Today, almost every fifth European is harmfully affected by vibration. Wave barriers placed on or embedded within the soil between source receiver can mitigate transmission of ground vibration, airborne be reduced a similar manner with screen acting barrier. As novel approach, present explores efficiency combining into one. To this end, numerical experiments were performed semi–analytic finite-element method for boundary-element sound propagation. This involved time-harmonic analyses carried out order to study performance various configurations focusing vertical rigidly attached surface soil. Parametric conducted achieved mitigation different types ground-vibration barriers, respectively. The combined effect then assessed investigate their potential possibly reducing negative impact lineside aim work, though, highlight metric, recently developed, which reports probability number residents who could annoyed intrusive railway It shown that single structural-element target reduction around 15% annoyance levels 12 dB insertion loss amounts 30% due noise.
