Extract

The noise nuisance caused to communities around airports is one of the greatest problems besetting present-day civil aviation. Considerable effort is being expended to meet the challenge of lessening the nuisance without impairing the continued development of air transport. Governments, operators, manufacturers and research institutions are all playing a part. In addition to local regulations designed to control noise near specific airports, legislation based on international agreements has for some years required new types of subsonic jet airliner to be certificated as meeting given noise levels. Currently, the successful development of “hushkits” is enabling many older types to be brought within these levels. At the same time, it appears likely that still more stringent limits will be set for new types as the future unfolds.
