During the past few years, the introduction of the large jet air liner has introduced new noises into the sky which has caused the public to be more aware than ever of the increasing nuisance value of aircraft taking off, landing, or on the ground. Much of this is being blamed unfairly on the jet air liner but the problem in any case remains with us.
For example, recent measurements given before the Society of Automotive Engineers are very revealing; here Baranek plotted the maximum noise levels on the ground when aeroplanes took off with a 5° take-off path.
