Abstract

As a consequence of the energy crises caused by several global issues, the need for renewable energy resources, particularly in producing electricity, augments to a depth- defying extent. Consequently, sound is a viable candidate for producing electricity as it is an under looked yet abundant renewable energy resource. Furthermore, among the various related studies, there is no definitive research that presents the relationship between acoustic energy and output voltage. This study aims to test the relationship between the acoustic energy levels of a particular environment and the voltage output of the AEPeH, and the significant difference between the voltage produced in a simulated and applied environment. Hence, the experimental-correlational directed research tackles on using simulated acoustic energy via speaker and applied acoustic energy via environments to manipulate output voltage. The AEPeH used a board of piezoelectric transducers connected to a Villard multiplier circuit, which used a multimeter to measure voltage. The AEPEH reached a peak voltage of 89 mV. A strong positive correlation was found between acoustic energy and output voltage. The implications of this study unveils the correlation between acoustic energy and output voltage, which in future application and further improvement, can be used to explore into the potential of sound potentially being viable to be aligned to the efficiency of conventional energy sources. Furthermore, there was no significant difference between the simulated environment and applied environment, signifying practicality in real-word scenarios. The results show possible viability in acoustic energy harvesters as an additional source of renewable energy that future researchers or entities may explore.
