Furthermore, the effect of the technological improvements on aircraft noise
levels differs between takeoffs (departures) and landings (approaches).
Decreased engine exhaust noise together with improved climb-out performance
(aircraft reach a higher altitude more quickly) have enabled major
reductions in departure noise levels. Approach noise has also recently
become a more prominent issue. Greater noise emissions from the fans and
compressors in high-bypass engines have increased the comparative importance—
and sometimes the actual noise levels—of aircraft approaches. One
further concern to be addressed is sideline noise produced by the reverse
thrust applied as aircraft land. This noise, particularly evident lateral to runways,
can be the subject of complaints, but usually has little effect on overall
noise contours because of the dominance of takeoff noise. 展开
