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 of
wave, mechanical wave that is an oscillation of pressure which need
medium to travel.
 As sound wave is a mechanical wave when it travels through a
medium it disturbs the particle of the medium these disturbance
created by sound could be used to produce electricity by the law of
thermodynamics.
 In our daily use we use many products in which the conversion
between sound energy and electric energy takes place For e.g.:- mic
, speaker , mobile phone ,transducers. However the amount of
conversion is very small and we require large amount of energy to
convert it so the problem is how we could convert efficiently.

SOURCES OF SOUNDS

4 Heavy Traffic 100
5 Wild Birds 80
6 Wild Frogs croak 100

Where can we harvest sound ?
Industries
Thermal plants
Nuclear plants
Roads
Auditorium
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.

Methodologies suggested
Method 1-By creating apparatus using curtain (diaphragm)
magnet and conductor

Method 2- By converting sound
energy>heat energy and then heat
energy>electric energy

Method 3-By using transducers such as
piezo electric material which converts

thermodynamics.
Uses principle of
Newton’s law.

available.
Less efficient. Efficient process.
Lengthy process & can
be only used in nuclear
power plants.
Time consuming & only
