Abstract
In order to survive in this modern world, electricity is an essential thing. Electricity allows us to power the technology we use every day. Without electricity, people can’t imagine their lives. As a developing country, Bangladesh still lacks electricity every day. The electricity supply to the rural areas is very poor. It is known that energy can be converted from one form to another form. As noise is the energy, it can also be converted into various forms of energy. Noise can be represented as a sound that is loud or unpleasant and causes disturbances such as street traffic sounds, construction sounds, airports, etc. Using a suitable transducer, noise (sound) energy can be transferred into a viable source of electricity generation. This can be accomplished by employing a transducer and converting noise-induced vibrations into electrical energy. Our main goal is getting enough energy, reducing the pressure of the main grid of electricity and decreasing fossil fuel imports. This paper presents the design and investigation of an energy harvesting system from noise. In this paper, an application is designed to get energy from noise by using a speaker as a transducer. Voltage has been stepped up by using a transformer, a diode which gives DC value which can be tapped into a battery and provide energy from the battery when it is needed. The embedded device was initially tested by clapping hands and tested further by using car horns. The vibrations created by car horns and other noises have been converted into electrical energy through the principle of electromagnetic induction. In total, the application produced optimal results of 0.5 - 1.0 volts which were stepped up using a transformer while maintaining the whole system being low cost and user-friendly.

Summary
Noise is a loud and unpleasant sound that causes disruptions, such as street traffic, construction noise, and so on [1]. High decibel sound or noise generates energy which is called sound energy. The electric energy created in the piezoelectric element was measured utilizing the acoustic excitation of the speaker connected to the resonator. In [8] present us information that a system has been updated and the system can convert vibration and sound into electrical energy. One of the piezoelectric materials (QB220-503YB) generated power at a measurement of 2057.2 (μW) at 96 decibels with a voltage of 3.894 (Vrms). A simple speaker was used as a transducer to generate emf in the presence of sound and vibration. The remainder of this paper focuses on the project’s outcome, with several data from the experiment provided and discussed in Section 3, and Section 4 containing the paper’s conclusion
