Check this Out! Researchers have developed a system of piezoelectric sensors that can be installed in theaters and concert halls to absorb sound waves and convert them into electricity. The system, described in a paper published in Physics of Fluids, aims to reduce the risk of hearing loss in public environments. The researchers used computer simulations to optimize the system, adjusting variables such as voltage, frequency, and sensor configuration. The system also features smart power management and uses environmentally friendly materials.
