Electric vehicles diffusion: changing pavement acoustic design?
Noise Mapping, 2021 Electric vehicles (EVs) are progressively entering into the current noisy urban ecosystem. Even though EVs are apparently quieter than traditional Internal Combustion Engine Vehicles (ICEVs), they have an impact on noise maps and road pavement designers ...

Can sensor-based noise mapping be a proxy of PM and permeability mapping?
Noise Mapping, 2021 In recent decades, road infrastructures have been the subject of numerous studies, aimed at ensuring reduced air and acoustic pollution. On the other hand, several studies showed that another important problem is dust load.

On the effects of rough ground and atmospheric absorption on aircraft noise
Noise Mapping, 2022 The noise received from an aircraft is modified by atmospheric attenuation and reflections from the ground. The interference of direct and reflected waves is simplest for a flat ground, whereas multiple reflections can occur for rough ground or ...

Noise pollution in rail transport. Case study: Baghdad subway
Noise Mapping, 2022 Noise pollution is one of the environmental factors that severely threaten humans’ mental, emotional, and physical health. One of the most significant sources of this pollution is the noise generated by traffic and urban transportation, mainly the urban ...

Urban background noise mapping: the multiple-reflection correction term [PDF]
, 2014 Mapping of road traffic noise in urban areas according to standardized engineering calculation methods systematically results in an underestimation of noise levels at areas shielded from direct exposure to noise, such as inner yards.

Shot noise of inelastic tunneling through quantum dot systems [PDF]
, 2004 We present a theoretical analysis of the effect of inelastic electron scattering on current and its fluctuations in a mesoscopic quantum dot (QD) connected to two leads, based on a recently developed nonperturbative technique involving the approximate ...
