Abstract - This paper present the sound to electrical energy that are many conversion of electrical energy from many others energy form like wind ,solar, biogas and others form. But in this paper we are focusing on the sound to electrical energy. We are surrounded by sound energy like Roads, Airports ,highways and street about to notice it. There are many feasible methods to get electricity from noise pollution and it is possible to running our devices with it.in this paper we have described two needed method to get Electricity ."LETS HOW COULD WE GOT IT".see below

Keywords - Sound Energy, Microphone, PZT Actuators and Electricity.

I. INTRODUCTION

II. METHOD

we all know that one special Law about energy that is known as "LAW OF ENERGY" energy is neither be created nor be destroyed its converted from one form to other form. we know that there are various form of energy form in our atmosphere and our surrounds which can play fabulous roll in our daily power requirements and need of electricity. In 2030 when the fossils fuels will at end off then other energy will full fill others needs.

Solar is an important energy which is available in the atmosphere today there are many research are on the process of this fabulous solar energy. there are many applications of solar energy like solar heater, solar cockers, solar panel which is use in our domestic house and commercials houses to fulfill our needs of power.

Renewable energy like hydro, wind, nuclear etc are most valuable energy generated form but as expect nuclear all above renewable energy generate less energy as our needs but these are requirements of costly and huge space to installed their instruments. Microphone and piezoelectric devices are playing a good roll in our less requirements power like these device generated less power in micro watts and milli watts at the few cost. Microphone has an unique ability to catch the sound and convert it into electrical energy its diaphragm.

when sound vibrations is on it then it has strain and stressed so that converted into the electrical energy and piezoelectric (PZT) is made of crystalline structure materials which direct convert mechanical to electrical energy and vice versa . my research paper is on the two method of converting electrical energy like piezoelectric and microphone by utilizing of wastes and pollutions of noise and create reliable and useful energy sources. Our daily life useable device charged by this .

The sound to electrical conversion is not a new concept this was proposed by first of all Los Alamos National Laboratory in collaboration with the Northrop Grumman Space Technology, USA. And they have used a generator in this a moving piston was used for the conversion .

Sound energy is converted into electrical energy by transducer. Here the transducer as a microphone which is to many application as like audience gathering, social gathering and covey message to others persons etc. here That microphone convert the sound energy into electrical energy at low level by capacitor bank boost that energy and charge our gadgets.

But this technology A microphone have to use to catch sound signal from the surrounding and convert it into the electrical energy. like we speak on microphone the microphone convert it into the electrical signal there is no need to re-convert it to its original form . 9v dc battery is installed to store the electrical signal and use as many application.

This will be a new concept because there is no such application or appliances are made to use direct from sound to run. The basic idea is that sound is mechanical wave. When sound travels through any medium then it disturbs the particles of that particular medium and these disturbances caused by the sound can be used to produce electricity. by this method many devices are made and installed in noisy areas.

Conversion of Electricity from the Sound Energy (Noise Pollution)

Table sound and electrical output

Fig 3 crystal materials

Piezo-electric crystal Piezo-electric format in human today scientists has prove in their research. Human contains one tone battery in the form of fats may be that fats use to run our small gadgets like mobile.PZT actuator is also a experimental instrument that can convert the sound into electricity that practical perform in Bangladesh used it in the train wheels. Electricity to store in big bank battery and that storages energy can be use in operating the FAN, TUBELIGHTS etc.

IV. METHOD 2

The second method is related to the piezo-electric device in this method the sound energy is converted into electrical energy by the help of piezo ? electric device. The strain is applied on the surface of the crystal then the due to deformation converted into electricity.

Material use in Piezo-electric In piezo electric materials are to use to converted the mechanical deformation to electricityLikes, Quartz, DNA whereas artificially ZnO, lithium ,niobatet, Lead Metaniobate shown in fig.

Fig5 measurement of pressure and volts.

Design and Cost This actuator is design as lead zirconate titante (PZT) ceramic, the PTZ is the white disk in the center of a brass diaphragm and the centre is coated as the silver the other area is coated as brass there is little bit space between silver and brass coated area due to this when mechanical stress is applied on or sound wave is applied then it form as sink and expension so that

mechanical phenomena that energy converted into electricity. The cost of the crystal shown in fig is very less as compaire to other actuator.because the device hardly $ 0.04.

V. PROJECT

In my project we have used both the actuators like the microphone and PZT because that if the microphone will not work the PZT actuator can be work and perform well .the project is performing well result during the experiment .this experiment was performed on the mobile when we have given sound energy the mobile started to charge when stop that then stop charging. Second experiment was to press the PZT crystal device then due to mechanical stress and strain the mobile was also charge the project shown in fig .

In future it can help to full fill power needs. It will good and less costly because it can run on

wasted energy. In 2030 when world feel remove its self from

fossils fuel the this type of device will play a good roll in power needs. Its other application in street light on the road due to vehicle sound the light will glow no other electricity is required it also reduce noise pollution.

CONCLUSIONS

There are various form of energy that we don't have notice about them but they may play vital roll in our daily life. This type device can reduce the noise pollution and as well as the us noise pollution from our atmosphere to run our daily life gadgets like mobile.

This device installed it at any noisy area and DC battery is connected to store and use its as our requirements.
