SOUND POLLUTION

Pollution is probably the most talked word of the world. It is in fact the process of making the elements of the environment dirty or harmful. Our environment is polluted in various ways and forms. Sound pollution is one of the forms of environmental pollution. It refers to the intolerable level of sound. The normal tolerance limit of sound is 45 decibels. When sound exceeds this limit, it becomes polluted. Sound pollution is created due to many reasons. The main reasons are rapid growth of population, increasing use of machines, vehicle horns, indiscriminate use of microphones etc. The effects of sound pollution are serious. It affects our daily life badly. It is very harmful for the patients. It interrupts the attention of study of the students. Often it makes people aggressive. People may also go completely mad due to sound pollution. So, it is a bare necessity that we stop sound pollution at any cost. To prevent sound pollution some places are declared 'silent zone'. Silent zone means a place where there is little or no sound. In other words, high sound is prohibited in such areas. Library, hospital etc. are such places. We can control sound by careful town planning and developing public awareness. The law enforcing agencies can also play a vital role in this regard.
