Noise is constant and loud sound. To measure the loudness, or volume of sounds, people use a unit called a decible. When a sound is louder than 70 decibels, it can cause noise pollution. Do you know that the noise from a vacuum cleaner or a motorcycle can results in permanent hearing loss after eight hours. The sounds of a concert are even more serious. They can reach as high as 130 decibles and may cause immediate and permanent hearing loss. Noise pollution can also lead to headaches and high blood pressure. If you are listening to music through headphones, and other people can hear it, it means the music is too loud and unsafe. If there seems to be a ringing or buzzing in your ears, it means the noise is affecting you and damaging your hearing. Wearing earplugs when you go to concerts or other loud events, and listrning to music through hedphones or headsets at safe levels can help you reduce the effects of noise pollution.
