Changes in noise levels in the city of Madrid during COVID-19 lockdown in 2020
TLDR
In this paper, an analysis has been carried out to describe the reduction in noise pollution that has occurred and to analyze the changes in the temporal patterns of noise, which are strongly correlated with the adaptation of the population's activity and behavior to the new circumstances.Abstract:
The lockdown that Madrid has suffered during the months of March to June 2020 to try to control and minimize the spread of COVID-19 has significantly altered the acoustic environment of the city. The absence of vehicles and people on the streets has led to a noise reduction captured by the monitoring network of the City of Madrid. In this article, an analysis has been carried out to describe the reduction in noise pollution that has occurred and to analyze the changes in the temporal patterns of noise, which are strongly correlated with the adaptation of the population's activity and behavior to the new circumstances. The reduction in the sound level ranged from 4 to 6 dBA for the indicators Ld, Le, and Ln, and this is connected to a significant variation in the daily time patterns, especially during weekends, when the activity started earlier in the morning and lasted longer at midday, decreasing significantly in the afternoon.read more

Analysis and Acoustic Event Classification of Environmental Data Collected in a Citizen Science Project
TL;DR: In this paper , a convolutional neural network is trained to automatically detect and classify acoustic events even if they occur simultaneously, but not all the categories are equally detected: the percentage of prevalence of an event in the dataset and its foregound-to-background ratio play a decisive role.

The Positive Effects of Covid-19 Lockdown on Environmental Attributes: A Review
TL;DR: In this paper , the authors inspected and narratively reviewed the observed effects of COVID-19 lockdown on the changes in the environmental quality based on secondary research data, and provided a distinct indication considering the impacts executed by the COVID 19 lockdown on air, water, soil, and noise as typical environment elements.

A spatiotemporal analysis of the impact of the COVID-19 outbreak on noise pollution in Tehran, Iran.
TL;DR: In this article , the authors studied the spatial and temporal patterns of noise pollution levels in Tehran before and after the outbreak of COVID-19 and found that the early months of the virus outbreak were associated with a significant pollution reduction.

Indirect effects of COVID-19 on the environment.
TL;DR: The research shows that there is a significant association between contingency measures and improvement in air quality, clean beaches and environmental noise reduction, and decreasing GHG concentrations during a short period is not a sustainable way to clean up the environment.
