Mapping Urban Environmental Noise Using Smartphones [PDF]
Sensors, 2016 Noise mapping is an effective method of visualizing and accessing noise pollution. In this paper, a noise-mapping method based on smartphones to effectively and easily measure environmental noise is proposed. By using this method, a noise map of an entire area can be created using limited measurement data.

Urban Background Noise Mapping: The General Model [PDF]
Acta Acustica united with Acustica, 2014 Surveys show that inhabitants of dwellings exposed to high noise levels benefit from having access to a quiet side. However, current practice in noise prediction often underestimates the noise levels at a shielded façade. Multiple reflections between façades in street canyons and inner yards are commonly neglected and façades are approximated as ...

Urban Noise Conflicts in Szeged [PDF]
Belvedere Meridionale, 2020 Noise pollution is a serious and complex city problem. While there are objective, measurable parameters for noise mapping assessments, since the effects of noise are also subjectively perceived, it has been difficult to accurately evaluate the urban problems and conflicts arising from noise.
