Abstract

Highlights: Analysis of noise pollution in Dublin is performed using 12 monitoring stations data. Noise pollution reduced considerably during lockdown imposed due to COVID-19 pandemic. Noise reduction is less at citycentre and airport but more in other areas across city. Abstract: Noise pollution is considered to be the third most hazardous pollution after air and water pollution by the World Health Organization (WHO). Short as well as long-term exposure to noise pollution has several adverse effects on humans, ranging from psychiatric disorders such as anxiety and depression, hypertension, hormonal dysfunction, and blood pressure rise leading to cardiovascular disease. One of the major sources of noise pollution is road traffic and the WHO reports that around 40 % of Europe's population are currently exposed to high noise/sound levels. This study investigates sound levels in Dublin, Ireland before and after the lockdown imposed as a result of the COVID-19 pandemic. The analysis was performed using measured hourly data from 12 noise monitoring stations between January and May, 2020. More than 80 % of the stations recorded high sound levels for more that 60 % of the time before the lockdown in Dublin. However, a significant reduction in hourly average equivalent sound and hourly minimum sound levels was observed at all stations during the lockdown period and this can be attributed to reductions in both road and air traffic movements.
