Introduction Can you imagine your life without your computer, mobile, lights and

other daily used appliances, it is really very hard to imagine our life

without these electric appliances.

Electric consumption is increasing drastically, on the other hand

production of electric power is limited.

It’s time to think of some alternative and green.

Here we are introducing an alternative :

SOUND!!!

Noise pollution to electric energy….???

Can sound be converted to useful energy…???


ALGORITHM


Generation of power from the

piezoelectric material. This is the

starting point of our project,.

Rectification of generated AC

voltage. As the power generated

from the piezo material is AC is

needed to be rectified.

Storage of rectified voltage.

Conversion of sound energy to

electrical energy

sound energy is a mechanical energy which travel in the form ofwave, mechanical wave that is an oscillation of pressure which needmedium to travel.

As sound wave is a mechanical wave when it travels through amedium it disturbs the particle of the medium these disturbancecreated by sound could be used to produce electricity by the law ofthermodynamics.

In our daily use we use many products in which the conversionbetween sound energy and electric energy takes place For e.g.:- mic, speaker , mobile phone ,transducers. However the amount ofconversion is very small and we require large amount of energy toconvert it so the problem is how we could convert efficiently.

Every where around us …..


Noise Levels in current world


Noise means any sound energy that has

random amplitude and frequency and

which creates disturbance in the ecosystem

thereby causing pollution.

Noise consists of super-positioning of

mechanical waves. Their direction of

propagation is in all direction and travels

with 330 to 345 m/s velocity.

Today due to road trafficking and airplanes

there is formidable amount of noise

production.

Noise pollution contributes about 3% in

the total global warming every year.

It creates a cacophony and leads to brain

stress, mental trauma and may also result in

permanent hearing loss (deafness) .

IEEE-2013 Piezoelectric transducers are used for

conversion of sounds into electric

energy. The produced electric energy

from multiple piezoelectric

transducers are stored in multiple

super-capacitors which are then

summed up and amplified through

adder and voltage multiplier circuits.

In mobiles, the vibrations generated

by keypad stress and sound waves

will apply to a permanently-polarized

material such as quartz (SiO2) or

barium titanate (BaTiO3) which

produces an electric field due to

imposed mechanical force.

Less efficient. Efficient process.

Lengthy process & can

be only used in nuclear power plants.

Time consuming & only

usable for high density
