Not all sound is considered noise pollution. The World Health Organization (WHO) defines noise above 65 decibels (dB)_ as noise pollution. To be precise, noise becomes harmful when it exceeds 75 decibels dB and is painful above 120 dB.                                                            

         Noise pollution is the noise that causes discomfort and harm to living beings’ mental and physical health.

         Noise pollution is caused by several phenomena including industrial activities, transports traffic, loudspeakers many more.

        Moreover, the noise of various machines being operated in different industries and various processes operating within these industries create the problem of noise pollution. The workers of these industries and the people of nearby areas are victims of such pollution noise of almost continuously, operating mechanical saws drilling, cutting, crushing are sources of considerable irritation and annoyance and highly disturbing.

          On the other hand, due to the ever-increasing number of motor vehicles in the cities, the problem of noise pollution is becoming more and more acute particularly, in the cities. Generally, the el-operated vehicles create noise of greater intensity. Traffic noise accounts for most polluting noise in cities.  For example, a car horn produces 90 dB, and a bus produces100 dB. The noise arising out of air transport is not continuous, but the intensity of such a noise is much higher than that generated from surface transport. A single aircraft produces130 dB.

            During social events and other festive occasions, people use loudspeakers in an unjustified manner. It also causes noise.

        Further, it affects the lives of animals and human beings physically and mentally. One of the most noise effects is" deafness”. Its high noise level (120dB) is immediate and permanent hearing damage. Additionally, noise makes people restless and tired. It causes disturbance in sleeping and loudspeakers to cause disturbance in the study. The human mind tolerates noise in a limited excess noise also causes headaches.

           Finally. Noise has a huge impact on the lives of animals and human beings. We have to grow more and more trees that absorb noise from 5dB to 10dB it may be controlled somehow. Besides devices that are not useable, we have to off them, wear air plug-in noise places and the sound of radios, television music volume must be in the limit to prevent noise pollution.
