Sound Event Detection for Human Safety and Security in Noisy Environments

IEEE 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

Review of anomalous sound event detection approaches

IAES International Journal of Artificial Intelligence (IJ-AI), 2019
<p>This paper presents a review of anomalous sound event detection(SED) approaches.  SED is becoming more applicable for real-world appliactaions such as security, fire determination or olther emergency alarms. Despite many research outcome previously, further research is required to reduce false positives and improve accurracy.

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 ...
