Noise map is an interactive dashboard visualising the noise pollution generated from aircrafts and other transport means around the globe. We collect live aircraft locations and conduct noise simulations to estimate how much noise is being felt at different location near airports.
Aircraft noise pollution refers to noise produced by aircraft in flight that has been associated with several negative stress-mediated health effects, from sleep disorders to cardiovascular disorders.
This work includes, among several topics, investigations into emerging noise reduction technologies, noise impacts from new aircraft concepts (e.g. Unmanned Air Vehicles), and the development of SARPs for future supersonic aeroplanes.
To mitigate adverse effects from aircraft noise on EU citizens’ health, the World Health Organisation Europe recommends reducing aircraft noise levels below Lden 45 dB and Lnight 40 dB. Air pollutant emissions from aviation have increased within the EU.
Annoyance due to aircraft noise has been recognized by authorities and policy makers as a harmful effect that should be reduced or prevented. Priority is given to noise reduction at the source (e.g., engine noise, aerodynamic noise) and reducing noise impact by adjusting operational procedures and take-off and landing trajectories. Attempts
As part of the CAEP/12 (2022) update to the ICAO Global Environmental Trends, four scenarios were developed for the noise trends assessment, resulting in the total contour area and population inside the yearly average day-night level (DNL) contours (55, 60, and 65 dB) for 319 global airports, representing approximately 80% of the global traffic.
15 wrz 2023 · The three main sources of aircraft noise are propulsive, aerodynamic, and other mechanical, thermochemical, and fluid dynamic processes. The chapter delves into addressing the gap of a lack of noise emission standards for unmanned aircraft.
