Re-surging airport noise: understanding aircraft noise dynamics during and after the COVID-19 pandemic at Dublin airport

Abstract

This paper explores the dynamics of aircraft noise patterns, examining the transformative impact of the COVID-19 pandemic on flight numbers and noise contours during the years 2021, 2022, and 2023 at a European airport. Focused on both peak and low flight months, the study explores how the aviation landscape experienced shifts during the pandemic and post-pandemic scenarios. As a transport hub for an island nation Dublin Airport is a key piece of national infrastructure but as the global travel restrictions took effect, the airport witnessed a substantial reduction in flight numbers, resulting in a notable decrease in airport noise and subsequent lower population exposure to environmental noise. This paper analyzes the trends in noise contours and flight frequencies during this period, shedding light on the immediate effects of the pandemic on aviation-related noise. Furthermore, as the restrictions gradually lifted, the study investigates the extent to which flight numbers and associated noise contours rebounded in the post-pandemic era. This comprehensive examination provides insights into the evolving environmental soundscape, capturing not only the changes during the pandemic but also the subsequent rise in flight numbers. The potential impact on societal expectations of aircraft noise is discussed.
