Sound Event Detection for Human Safety and Security in Noisy Environments

open access: yesIEEE Access, 2022
The objective of a sound event detector is to recognize anomalies in an audio clip and return their onset and offset. However, detecting sound events in noisy environments is a challenging task. This is due to the fact that in a real audio signal several

Detecting Anomalous Noise Events on Low-Capacity Acoustic Sensor in Dynamic Road Traffic Noise Mapping [PDF]

open access: yesThe 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.

Effects of COVID-19 lockdown in Milan urban and Rome suburban acoustic environments: Anomalous noise events and intermittency ratio

open access: yesThe Journal of the Acoustical Society of America, 2022
The COVID-19 pandemic affected the acoustic environment worldwide, entailing relevant reductions of equivalent noise levels (LAeq) during this exceptional period. In the context of the LIFE+ DYNAMAP project, two wireless acoustic sensor networks were deployed in Milan and Rome.

Different types of criteria for dealing with anomalous noise events in urban environments under stable road traffic flow conditions

open access: yesApplied Acoustics, 2023
The management of anomalous noise events in the assessment of environmental noise of specific sources is an important issue for determining the actual exposure of the population to noise pollution. Of all the sources currently considered in the European Noise Directive, road traffic is the most important in cities, both in terms of its temporal and ...

Satellite-Observed Thermal Anomalies and Deformation Patterns Associated to the 2021, Central Crete Seismic Sequence

open access: yesRemote Sensing, 2022
Nowadays, there has been a growing interest in understanding earthquake forerunners, i.e., anomalous variations that are possibly associated with the complex process of earthquake evolution.

Technical methods of national security supervision: Grain storage security as an example

open access: yesJournal of Safety Science and Resilience, 2023
Grain security guarantees national security. China has many widely distributed grain depots to supervise grain storage security. However, this has led to a lack of regulatory capacity and manpower.

Surface latent heat flux as an earthquake precursor [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2003
The analysis of surface latent heat flux (SLHF) from the epicentral regions of five recent earthquakes that occurred in close proximity to the oceans has been found to show anomalous behavior.

Investigations of anomalous gravity signals prior to 71 large earthquakes based on a 4-years long superconducting gravimeter records

open access: yesGeodesy and Geodynamics, 2017
Using continuous 1-Hz sampling time-series recorded by a SG (superconducting gravimeter) at Hsinchu station, Taiwan of China, we investigate the anomalous gravity signals prior to 71 large earthquakes with moment magnitude larger than 7.0 (Mw7.0 ...
