Changes in Ambient Urban Infrasound During the COVID-19 Pandemic
Session: Infrasound and the Seismo-Acoustic Wavefield III
Type: Oral
Date: 4/22/2021
Presentation Time: 10:45 AM Pacific
Description:
Infrasound is a valuable and poorly utilized resource in understanding urban environments. While studies of natural signals often make use of low-frequency acoustics, discussions of anthropogenic signals usually consider only the audio range. Shutdowns related to the COVID-19 pandemic in early 2020 reduced human activity throughout affected areas, greatly impacting urban acoustics. We consider data from an infrasound array in Las Vegas, NV, which recorded throughout the shutdowns. The array distinguishes the times of day and weeks during which acoustic power sees the greatest declines. It further displays variations in said declines geographically. These results provide a clearer view of low-frequency acoustics, both during and outside of shutdowns.
