Most of the complaints centered around airplane noise, but other issues included aircraft altitude, frequency of overflights, disturbance of speech, disturbance of sleep, vibration, early morning ...
Sleep: A recent study monitored the sleep of people living near flight paths and found that those who were exposed more frequently to even moderately loud aircraft noise (55 decibels or more ...
The Republic XF-84H "Thunderscreech" is an American experimental turboprop aircraft derived from the F-84F Thunderstreak.Powered by a turbine engine that was mated to a supersonic propeller, the XF-84H had the potential of setting the unofficial air speed record for propeller-driven aircraft, but was unable to overcome aerodynamic deficiencies and engine reliability problems, resulting in the ...
For a brief period of time on Monday, it sounded a bit like things were cranking up for the Stuart Air Show.
Military aircraft surreptitiously creating sonic booms. (This origin does not explain sounds heard before supersonic flight, but could be extended to include military cannon-fire practice.) Earthquakes : Shallow earthquakes can generate sound waves with little ground vibration: The "booming" sound is heard only locally, near the epicenter .
Roadway noise and aircraft noise are the most pervasive sources of environmental noise. [2] Social activities may generate noise levels that consistently affect the health of populations residing in or occupying areas, both indoor and outdoor, near entertainment venues that feature amplified sounds and music that present significant challenges ...
The footage, believed to taken from a terminal inside the Ronald Reagan National Airport, captured the moment of impact between AA Flight 5342 and the Army Black Hawk helicopter at about 9 p.m.
