6. Conversion of noise into electrical form
• Noise is nothing but a kind of sound. A sound made of mechanical waves. This waves when incident
on any surface create pressure
• The sound pressure depends upon intensity of noise and distance from the source.
• Sound pressure generates sound power given by
Pac= ξ2∗ω2*Z*A= I* A ( I= power intensity, A= Area of surface)
This sound power when incident to a transducer can convert noise into electrical pow

Prototype of sonic noise to electrical converter

8. APPLICATIONS
Battery charging circuits
for street lights
Auxiliary power
generating sources for
airports and aero drams
Auxiliary power
generating
sources for
factories dealing
with great
amount of noise
everyday

10. where can we harvest sound ?
every where around us :
Nuclear plants
Explosions
Industries
Thermal plants
Roads
Auditorium
Conclusion :
Sound is not continuous form of
energy source and difficult to
harvest but with help of piezo
electric material it can be over
come.
