daily causes of noise pollution in our streets, public hi-way.
Industrial Machinery – there are so many various examples of
industrial machinery that creates severe disturbing and

design.
9. Control of noise pollution
Control of Noise Pollution by obstructing the
path of Noise
By constructing soundproof buildings, the menace of
sound pollution can be minimized.
Plants also help in controlling noise pollution because
they absorb high frequency sound waves. Thus,
planting trees along the roads help in controlling noise
pollution.
