Wäre ganz lieb, wenn mal eine drüber kuckt und mal Grammatik und Rechtschreibetipps gibt!

Noise pollution is unwanted human-created sound that damages the environment.
Noise pollution can be caused by many sources including highways, vehicles, police cars, ambulances, factories, concerts, air-conditioners, aircraft, helicopters and alarms. The word "noise" comes from the Latin word "nausea" which means seasickness. Noise pollution can be harmful to animals. High levels of noise pollution could interfere the natural cycle of animals. Perhaps the most extreme damage caused by noise pollution is the death of beaked whales, brought on by the extremely loud (up to 200 decibels) sound of military sonar.
Governments have traditionally viewed noise as a "nuisance" rather than an environmental problem. In the United States and Canada there are no national, provincial, or state laws that give protection against noise. Now, let me tell you something about sound. Sound is a physical phenomenon that stimulates the sense of hearing. It spreads in form of sound waves. These waves are longitudinal, mechanical waves, because the direction of the wave spreading is the same as the oscillation direction of the particles. They spread in form of pressure fluctuation. Only the energy of the wave is transmitted through the medium. No part of the medium actually moves far. In human beings, hearing takes place whenever vibrations of frequencies between about 15 and 20,000 hertz reach the inner ear. The hertz is a unit of frequency equalling one cycle per second. Sounds of frequencies higher than about 20,000 hertz is called ultrasonic. Sounds of frequencies lower than 15 hertz is called infrasonic.
