Aviation noise

Helping orphans the way you would do it
Aviation noise is one of the most publicised forms of environmental noise.

Starts, approach and landing of aircraft cause dangers for health. A starting aircraft may lead to a noise of more than 100 dB(A) at the ground. Since aircraft landing in inner-city airports are often lower than 200 ft (60 m) above roof level, they can cause a noise of more than 95 dB(A).

Aviation noise is a health problem. It is said to cause heart diseases, immune deficiencies, neurodermatis, asthma and other stress related diseases. It is an economic problem as well. Some calculations show that the economic costs of health dangers exceed the economic benefit of aviation more than twice over.

The most serious noise issue, however, is that of aircraft movements after 7 p.m.

Since aviation noise became a major public issue in the 1960s and 1970s, governments around the world have brought in legislative controls, and aircraft designers, manufacturers, and operators have developed quieter aircraft and more careful operating procedures. Modern fan-jet engines, for example, are quieter than the pure jets of the 1960s.
