For you who live near the airport is often subject to certain aircraft bisingnya vote. Sometimes to make sleeping difficult. All that may soon be overcome. In the Netherlands in the autumn will be testing anti noisy equipment. Hearing the sound reducer developed by research institute TNO, Delft, will be installed in some homes. With one button, all the lost votes.

Sound pollution problem is solved a difficult environment. Aircraft, for example. Voters who dihasilkannya a certain frequency is low, so any transparency. Thick walls and even installing soundproof is not susceptible to withstand bisingnya engine aircraft. Various cities in the world face the same problem: Tokyo, New Delhi, Mexico City, New York, Amsterdam. Parahnya again, more and more settlements built in the vicinity of an airport because menyempitnya land. As a result, many more who suffer the impact of air pollution.

How it works
Professor Frank van de Berg led the TNO to develop a research tool 'anti noisy'. He explains how these tools work. "First you have to analyze the sound, know how to shape." Voters can be seen in the form of graphs, called sound waves. Then, with the computer calculations can be made that sound waves opposite. How it works simply. If any increase in the wave of sound waves created equal, and so on down. Waves, as it is called anti-vote. "When you play two waves of opposite each other at the same time, they will kill each other.'s Room will be quiet," said Professor Frank van de Berg.

Sleep soundly
Technical equipment used for anti noisy work most effectively for the voice that is easily estimated. Fortunately patron sound waves aircraft including the estimated easy. In addition, the wave of creation is also very wide. Therefore, as the wave can be measured and made sound waves before the plane disappeared. This technique can reduce the sound to 18 Decibel.
In the bedroom at the house near an airport with a microphone will be installed to measure the sound aircraft. Microphone is connected to the computer. At the time the aircraft drift, microphone will capture the sound and the computer immediately and make a sound menganalisanya competitor. The result was issued through the direct vote of the already installed in the room. Anti sound waves will be directly off the aircraft through the sound. Only one key needed to activate all.

"Fortunately this anti vote can only be applied to the sound with low frequency sounds so as wekker and others can still be heard," explained Prof.. van de Berg.

Pilot
Gert Jan Meijer, an account manager at the Port of TNO Air Schiphol Netherlands, responsible for implementing anti-sound technology in the airport area.

'The first version for the trial will be in five pairs of houses in the vicinity of Schiphol Airport. We believe this technology, anti-vote will be successful. However, some issues still need to be corrected. We also still need to examine how people will use this tool, as well as what they want, "said Gert Jan Meijer.
