DEVELOPMENT AND VALIDATION OF AN EFFICIENT NOISE POLLUTION ENERGY CONVERSION SYSTEM

Abstract— Noise pollution is one of the repercussions of modernization. Noise pollution is an acoustic pressure signal that has the potential to produce low-level electrical signals and thus the main objective of the research work is to optimize the electrical signal produced from the noise pollution so that any unwanted sound can be referred to as Noise. With the advancement in technology, various compact and highly efficient sensors suitable for acoustic energy conversion are commercially available and these sensors can convert the sound pressure level (SPL) into a suitable low-level electric signal. A suitable amplification-rectification unit can improve the quality of the electrical signal and the power management unit must be used for the storage of the energy. This paper presents the development and validation of an effective and better experimental model for noise pollution energy conversion. The developed model is tested in a real environment under diverse conditions. The proposed model has produced a 1.72 V electrical signal at 101dB SPL input, without any amplification. The developed amplifier module is designed to support the low-level electrical signal and provides a voltage gain of 2×103. The application outcomes justify the superiority of this model over others as available in the literature.
