(1) Background: Transition to smart cities involves many actions in different fields of activity,
such as economy, environment, energy, government, education, living and health, safety …

To investigate the structure-borne noise characteristics of U-shaped girder bridges (USGBs)
with fully-enclosed sound barriers (FESBs), an analysis model of the USGB-FESB coupling …

Objective: Excessive noise is unpleasant and induces several physiological and
psychological effects. Noise pollution is a potential threat to humans, particularly those …

Reducing environmental noise in urban settings, ie, unwanted or harmful outdoor sounds
produced by human activity, has become an important issue in recent years. Most countries …

Objectives Traffic management is challenging during construction because of the effects of
traffic congestion, travel time, delay, and queue length. Long-term work zones on urban …

Monitoring and managing environmental problems, particularly those impacting human
health such as noise and air pollution, are essential. However, the current implementation …

Road traffic noise visualization is vital in three-dimensional (3D) space. Designing noise
observation points (NOPs) and the developments of spatial interpolations are key elements …

Railway noise has become a significant concern for trackside residents due to increased
volume of high-speed passenger and freight train traffic. To address this, active measures …

Purpose To mitigate the urban traffic noise within the frequency range of 100–400 Hz, this
paper proposes a novel ventilated metamaterial barrier (VMB). Methods With the help of the …

摘要为提高公路声屏障的降噪性能, 从声波绕射和反射两个角度考虑, 通过声学有限元法(finite
element method, FEM) 分别探究声屏障顶端类型和表面扩散体间距, 宽度以及高度对声屏障 …
