posted on 2021-05-04, 09:20 authored by Jennifer Glover, Daniel O'BoyDaniel O'BoyAircraft are notorious for their large sound profile, yet noise is one of the most significant limiting
factors for aviation growth. In 2011 the World Health Organisation identified environmental noise as
the second largest environmental health risk in Western Europe [1]. Prolonged exposure to
unacceptable noise levels (≥55 dB Lden (day evening-night level)) is linked to conditions including
tinnitus, hypertension, coronary heart disease and myocardial infarctions [2]. Factor such as these
have led organisations like the Advisory Council for Aircraft Research and Innovation in Europe
(ACARE) to target a reduction in perceived noise by 50% for new aircraft entering into service in
2020 relative to the year-2000 [3]. Moreover, airport operations are often restricted at night, due to
factors such as noise therefore noise control offers a potential increased capacity....
