Noise Pollution We know the sounds of cities are loud enough to cause great harm to people's hearing .S. One person out of twenty has got some hearing loss. And all over the world the situation is getting worse and worse all the time since the noise increases with the population. With the development of machines, noise has also increased greatly in the 20thcentury. We live surrounded by loud planes, trucks and electric tools. TV sets and radios add up to 90 or J00 decibels, a certain unit used to measure the loudness of sound. A normal dialogue reaches 55 decibels; a plane goes to 100, and an ordinary train, reaching the station, can be twice as loud as the loudest plane. Disco music reaches about 118. At decibels the ear stops hearing sound, and pain starts. How terrible if things go on like this! We know the sounds of cities are loud enough to cause great harm to people's hearing.

At 120 decibels the ear stops hearing sound, and pain starts. How terrible if things go on like this! So we should take some effective ways to stop noise pollution and get a peaceful world back. Noise pollution can cause just as many damaging effects on people's health as other forms of pollution. Exposure to excessive noise can cause hearing loss, stress, lack of sleep, irritability, indigestion, heartburn, high blood pressure and ulcers. In 1985, the Noise Control Act was enacted; however, the law is too lax and is seldom adequately enforced. Fortunately, the Environmental Protection Administration (EPA) plans to have amendments to the law passed by the end of the year. The revised law would prohibit building renovations and interior decorations at noon, and between 6:00 p.m. and 8:00 a.m. in residential areas. The EPA also plans to ban karaoke singing at home during lunchtime and from 10:00 p.m. to 8:00 a.m. Those who violate the amended law would be fined a maximum NT$30,000. Hopefully the revision to the Act will be passed as scheduled. More importantly, it must be strictly enforced. Authorities responsible for implementing the law, especially environmental protection authorities and the police, must never shirk their duties in enforcing legislation. Other steps should be taken to protect people from the damaging effects of environmental noise. Such steps include locating residential buildings as far from noise sources as possible, banning the honking of car horns in certain areas, and planting more trees in front of buildings to absorb noise.
