The noise signature of small Unmanned Aerial Systems (sUAS) is highly influenced by
specific operating and weather conditions. Accurate noise assessment of sUAS operations …

The impacts of noise pollution on birdsong have been extensively investigated but potential
long-term effects are neglected. Near airports, where noise levels are particularly high, birds …

This work explores strategies to change the directivity of sound radiated from an oscillating
metamaterial plate. To this end, the vibro-acoustic behavior of a plate that hosts an array of …

Metropolitan airports constitute an environmental nuisance, mainly due to noise pollution
originating from aircraft landings and takeoffs, affecting the wellbeing of the airports' …

While the volume of air traffic continues to rise, there are concurrent shifts in aircraft fleets
and advancements in technology aimed at enhancing aircraft efficiency, sustainability, and …

Four time–frequency analysis techniques, namely the short-time Fourier transform, the
wavelet transform, the polynomial phase estimation and the Chirplet transform, are used in …

A thrust reverse noise detection methodology for airports is developed and tested in terms of
meeting the restrictions at Madrid-Barajas airport. The detection is based on thresholds …

In recent years there has been a renaissance in the field of aircraft flight performance with a
number of developments centreing mostly on environmental performance, sustainability …

When noise map** airports, the main noise sources are take offs and landings. But
aircrafts' taxi noise can also be important, and should be considered, for instance when …

There are conflicting trends in the impact of aircraft noise as increased air traffic is offset by
advancements in low noise aircraft technology. This paper considers the case of Dublin …
