Abstract

The present paper deals with monitoring of Noise Pollution at different places of Chidambaram town during Deepawali festival. The Noise Pollution is increasing considerably in the last three years and it is recorded maximum in 2015 as compared to 2014 and 2013. During the present study the noise levels were measured with the help of sound level meter at nine different locations during Deepawali festival. It was clear from our study that the noise levels are extremely elevated and are found to be above the prescribed limits of CPCB in all the zones. The main sources of noise pollution are loud speakers, powerful sound systems, orchestra, drums, etc. Major effects of noise pollution include interference with communication, sleeplessness, and reduced efficiency. Public education appears to be the best method as suggested by the respondents. Noise pollution has been well recognized as one of the pollutions that affect the quality of life in urban areas across the globe. In a town like Chidambaram, apart from traffic noise and noise generated due to construction activity, the major contributing source is noise produced during festivals. Present study analyses the trend and status of noise generated during an important festival Deepawali festival at different location in Chidambaram town for last three years. As per data obtained from the Central Pollution Control Board (CPCB), it is observed that there is no significant decrease in noise level at most of the places in year 2015 as compared to earlier years.

Abstract

The environmental pollution is increased due to the emission from the automobile vehicles and it is uncontrollable due to the increase in the number of vehicles on the road. So, our aim is to reduce and control the emission and noise from the engine using aqua silencer. The reason why we go for aqua silencer is, in today life the air pollution causes physical ill effects to the human beings and also the environment. The main contribution of the air pollution is automobiles releasing the gases like carbon dioxide, unburned hydrocarbons etc. In order to avoid this type of gases by introducing this aqua silencer. An Aqua Silencer is mainly dealing with control of emission and noise in automobile exhaust. Activated by using charcoal, perforated tube and outer shell it is constructed. An aqua silencer is fitted to the exhaust pipe of the engine. The activated charcoal filters the harmful sulphur and nitrous content produced from the engine. The sound produced under water is less bearable than it produced in the atmosphere. This mainly because of small sprockets in water molecules, which lowers its amplitude thus, lowers the sound level. Because of this property water is used in this silencer and hence its name AQUA SILENCER. It is tested in single cylinder 4- stroke diesel engine the noise and smoke level is considerable less than the conventional silencer. So absorb the gases from the engine and release much less position in the environment. The noise and smoke level is considerable less than the conventional silencer, no need of catalytic converter and easy to install.
