Methods for Noise Event Detection and Assessment of the Sonic Environment by the Harmonica Index
Applied Sciences, 2021 Noise annoyance depends not only on sound energy, but also on other features, such as those in its spectrum (e.g., low frequency and/or tonal components), and, over time, amplitude fluctuations, such as those observed in road, rail, or aircraft noise ...

Detecting Anomalous Noise Events on Low-Capacity Acoustic Sensor in Dynamic Road Traffic Noise Mapping [PDF]
The 4th International Electronic Conference on Sensors and Applications, 2018 One of the main aspects affecting the life of people living in urban and suburban areas is their continued exposure to high road traffic noise (RTN) levels, traditionally measured by specialists working on the field. Nowadays, the deployment of Wireless Acoustic Sensor Networks (WASN) has allowed to automate noise mapping in Smart Cities.

An algorithm to detect non-background signals in greenhouse gas time series from European tall tower and mountain stations [PDF]
Atmospheric Measurement Techniques, 2021 We present a statistical framework to identify regional signals in station-based CO2 time series with minimal local influence. A curve-fitting function is first applied to the detrended time series to derive a harmonic describing the annual CO2 cycle. We

Effects of COVID-19 outbreak on the sound environment of the city of Milan, Italy
Noise Mapping, 2021 In this paper, we present the results of the noise monitoring in the urban area of Milan, Italy, associated with COVID-19 outbreak. In order to limit the diffusion of the pandemic, Italy adopted growing levels of restrictive measures, which ended with a ...

Global Nuclear Explosion Discrimination Using a Convolutional Neural Network
Geophysical Research Letters, 2023 Using P‐wave seismograms, we trained a seismic source classifier using a Convolutional Neural Network. We trained for three classes: earthquake P‐wave, underground nuclear explosion (UNE) P‐wave, and noise.
