Noise pollution is otherwise known as sound pollution, which has been one of the most uncontrollable problem in the recent years. Noise pollution usually affects the people from all age group. It is mandatory to know the cause, effects and preventive measures of the sound pollution in order to prevent the negative impacts of Noise pollution on the human parts. When there is an excess level of Noise, the environmental pollution occurs. This Noise disturbance is very dangerous to the health of both animal as well as human beings. Compared to the water and soil pollutions, the Noise pollution has less impact on human body.
Source of Noise pollution
There are a lot of ways that the Noise pollution occurs, however it can be categorized into indoor and outdoor.

Control of noise pollution
It is bit difficult to control the excess level of noise pollution however we can slow the noise pollution by reducing noise level at source. By promoting vibration control and using sound absorption material, one can reduce the effects of Noise pollution gradually. Also, it can be reduced by prescribing exact noise limits for traffic and construction work. Some of the control method includes
- Save plant and trees.
- Try to plant more trees like neem, coconut and ashok trees.
- Spread general awareness about Noise pollution through TV and social media.
