- Turn off sound devices when not in use.
- Close the door when noisy machines are to be used.
- Lower the volume of devices such as television to a desirable level.
- Use earplugs while listening to music.
At mass level, it can be verified by -
By planting trees in large numbers to create buffer zones of vegetation, which absorb noise.
Public awareness of the need to fight cot noise pollution.
Application of engineering control techniques such as alteration and modification of the design to reduce noise from equipment and machinery, and by the construction of a sound barrier or the use of sound absorbers in industrial and industrial sites can significantly reduce noise exposure.
Construction of institutions and hospitals away from airports, railways and highways.
Improved building design can also reduce the impact of noise pollution.
Strict legislation at central and state levels to control air pollution in workplaces, urban centers, etc.
