The document discusses the prospects of converting noise pollution into electricity. It begins by defining noise pollution and its health effects. It then proposes that as conventional energy sources are exhausted, noise pollution could become a new renewable energy source since sound has energy that can be converted into other forms. The objective is to identify ways to convert noise pollution into electricity. It describes approaches like using microphones and piezoelectric transducers to harvest energy from oscillating sound waves. A model is created and tested, showing increased current output with higher sound levels. Advantages are reducing noise pollution while generating power, with potential to power lights with vehicle horns. Further research is needed to improve efficiency and affordability.

3. Background:
• Any unwanted sound that creates
disturbance into the normal functioning
of human activity is defined as noise.
• Regular exposure to the unwanted sound
levels may create many psychological
and anatomical problems in the human
body.

4. Introduction:
• By the year 2050, all the conventional energy resources would get exhausted.
• According to the law of conservation of energy, 'Energy can neither be created, nor
destroyed; but can be converted from one form to another'.
• Noise in itself has energy in it.
• There are various forms of renewable energy i.e. solar energy, wind energy, etc.
• But noise pollution in itself can can be the new renewable energy that can be called
as the 'Noise Energy'.

5. Objective:
• To identify the possible ways to convert noise pollution to electricity.
• To create a model that may convert noise pollution to electricity.

6. Approach:
• Sound energy is the mechanical form of energy which travel in the
form of oscillations.
• The sound wave displaces back and forth because of the potential
energy compression and the kinetic energy of the oscillation.
• This energy could be harvested in the two possible ways.

13. Advantages:
• Due to the conversion of sound energy to the electric energy it is
possible to use energy in abundance.
• Lighten the street lights with a vehicle's horn.
• The heavy noise pollution at the source could be converted to the
electricity.
• With this technology, noise pollution could be reduced.

14. Future Prospects:
• To increase the efficiency of the system so that it will increase the
power.
• To reduce it's initial cost.
• To make the installation cheaper.
• To make it work effectively at the places with low noise levels.

15. Conclusion:
• By the year 2050, when the world would have to cut off all it's
fossil fuel based plants, noise energy will play a crucial role in
coping with the energy crisis.
• It is a future energy.
• The efficiency of the mechanism has to increased.
• The change in material opens new dimensions for research in
the field of Material Science.
