Discovered by researchers from Cornell University found that exposure to extreme noise have ill effects. A recent study has said that the extreme noise such as jet traffic affect the ability of children to reading and studying in the long run, if they live near airports.

Said Gary Evans, the international expert in noise or noise pollution, a psychology professor at Cornell University, and colleagues said that Europeans were the first long-term study on a group of children before the opening and closing of the airports in which they live nearby.

And this study confirmed that the noise is the cause of the difference in the ability of children to learn and read. Previous studies had reported that severe noise pollution affects children's ability to learn, but they were quick studies with a cross-sectional sample, comparing children who live near airports with others in a quieter place.

The latest study in this area for the children of Germans moved from an environment full of noise to a quiet environment, children and the children moved from a quiet environment to another, full of noise.

But Gary Evans says that the problems that have occurred in learning to read and memory can be treated to move to a quiet environment. This occurred in the study after closure of the airport, which was the cause of noise pollution.

This is the first study of its kind to address the impact of noise on learning to read and memory, attention and understanding speech in children.

The researchers analyzed data on 326 children aged ten years, on average, live near the old airport was on the verge of closure, and near the site of the new airport. Children were assessed three times before six months of closing the old airport and the opening of the new airport and after a year and two years of opening of the airport.

Gary Evans says that there is a relationship between exposure to noise and problems learning to read may also be the ability to understand speech and memory in the long run for children of primary school age. But before the search on the children before and after the closure of the airport, there was no greater proof of this relationship and the impact of noise.

Said Gary Evans, who studies the impact of noise for many years that the study is further evidence that exposure to noise has serious implications for health and education for young people and adults.

In this context, monitoring cardiologist famous (Christian Bernard) is the leading open-heart surgery in the world in his fiftieth way to heart health, said that the most important reasons that lead to heart attacks and was on her head - along with excessive smoking - Continuous exposure to noise and noise and sounds high.

The doctor according to the research and numerous studies conducted over twenty years to complete the human body resists noise experienced by different patterns and images in two ways:

First: the so-called negative reaction as more and more of the hormone cortisone excreted, leading to higher pressure as a kind of supplement act to address the noise and bustle.

Second: the so-called positive reaction where the body run through a real battle against noise increases the production of adrenal hormones and Alnodadnalin to resist the negative effects caused by noise in various of its members.

In both methods, and when exposed to aggression voice raucous body produces hormones to resist stress and tension and cases of various emergency, and therefore the advice to people who give the doctor Bernard is to avoid noise daily as far as possible that we face every day in our everyday life, such as noise, traffic and crowded streets and places loud, and also recommended the need to asylum from time to time to remote quiet places to get rid of the effects of crowding and discharging cargoes of anxiety and tension, which carried the body inside.

On the other hand, according to research in Egypt that the increasing road accidents, among other things due to the large number of noise that surrounds the driver inside the vehicle or outside as the impact of noise beyond the hearing to the weakening of the eye to receive the dimensions of the vision in front of the driver.

The study stated that the noise affecting the partial loss of hearing may temporarily turn into a permanent one, according to the severity of the noise and lead to obstruction in the case of recurrence, as well as the impact of noise on the focus and attention.

She pointed out that the noise also affect the mental health of man leads to insomnia and sleep disorders and increased rates of stress, anxiety and high blood pressure and hormonal and biological changes that affect the organs of the body. She explained that the human needs of an ocean does not exceed the noise level with 35 dB

So that he can indulge in the comfort or sleep and he could not bear the noise exceeds 85 decibels.

The study called for an integrated strategy to promote environmental awareness and reduce the increasing noise, which said that man himself has caused in most cases, away from the field of industry and labor
