SummarySome measurements of the noise of a pulse jet working in the open have been made Octave analyses show that the bulk of the noise energy is contained in the fundamental, the source approximating to the classical simple acoustic source This results in a relation for the mean noise level in decibels,where ρo is the ambient air density, c the ...

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 ...
