Airframe Noise-The Next Aircraft Noise Barrier
Journal of Aircraft, 1974Progress in quieting the commercial aviation fleet has been achieved by reducing the noise generated by jet engines. Recent tests have indicated that noise produced by airflow over aircraft surfaces (lifting surfaces, landing gear, flaps, and cavities) is only 8 to 10 EPNdB below certification requirements for current aircraft and will likely be a ...

Aircraft Noise Indexes for Effect Oriented Noise Assessment
Acta Acustica united with Acustica, 2010This article discusses aircraft noise effect assessment with noise effect indexes, such as have recently been developed for noise monitoring purposes at the airports of Zurich and Frankfurt. Aircraft noise indexes are noise assessment instruments that express the overall effects of aircraft noise as a single figure which reflects the total amount of ...

The Psychological Cost of Aircraft Noise for Children*
Zentralblatt für Hygiene und Umweltmedizin, 1999Psychological effects of aircraft noise exposure on children have only recently been addressed in the literature. The current study took advantage of a natural experiment by the opening of a new airport, exposing formerly nonexposed children to low aircraft noise. In this prospective longitudinal investigation, which employed nonexposed control groups,

Tracking Radio Noise on Aircraft
Transactions of the American Institute of Electrical Engineers, 1950RADIO NOISE INTERFERENCE reduction methods for use in aircraft have not received adequate attention in recent years. Almost complete reliance is placed on equipment covered by military specifications, in spite of the fact that little or no equipment meeting the specifications is available.

Aircraft magnetic noise sources
8th International Congress of the Brazilian Geophysical Society, 2003Aeromagnetic aircraft and data acquisition systems generate magnetic interference which can effect the quality of the data collected. Many people believe that traditional aircraft compensation, which models the permanent, induced, and eddy-current sources, can remove all of this interference.

Noise transmission into a light aircraft
16th Aerospace Sciences Meeting, 1978An analytical study on noise transmission into a cabin of a twin engine G/A aircraft is presented. The solution of the governing acoustic-structural equations of motion is developed utilizing modal expansions and a Galerkin type procedure. The exterior noise pressure inputs are taken from available experimental data.

The Causes of Noise in Aircraft
Aircraft Engineering and Aerospace Technology, 1930THE advantages which arise from the directness and speed of aircraft, and the high record for safety held by Air Lines like Imperial Airways, contribute to the increasing popularity of air travel. With many persons, however, the chief deterrent at present is understood to be the discomfort caused by the noise experienced, and there is no doubt that ...
