High-Precision Dynamic Traffic Noise Mapping Based on Road Surveillance Video

open access: yesISPRS International Journal of Geo-Information, 2022
High-precision dynamic traffic noise maps can describe the spatial and temporal distributions of noise and are necessary for actual noise prevention. Existing monitoring point-based methods suffer from limited spatial adaptability, and prediction model ...

A WASN-Based Suburban Dataset for Anomalous Noise Event Detection on Dynamic Road-Traffic Noise Mapping [PDF]

open access: yesSensors, 2019
Traffic noise is presently considered one of the main pollutants in urban and suburban areas. Several recent technological advances have allowed a step forward in the dynamic computation of road-traffic noise levels by means of a Wireless Acoustic Sensor

PAC-ZNN for Robust Target Tracking in WSNs Against Complex Polynomial Noise [PDF]

open access: yesSensors
In wireless sensor networks (WSNs), angle of arrival (AOA) and time difference of arrival (TDOA) localization systems relying on distributed sensor measurements degrade significantly under high-order time-varying noise.
