Webpower-harvesting sensors, infrasound, sub-audible. (Keywords) I. INTRODUCTION: Infrasonic waves are sub-audible acoustic waves which typically lie below the human hearing threshold (usually between 0.1 to 10 Hz, sometimes going up to 20Hz).While these waves cannot be “heard” by humans, WebInfrasound at levels generated by turbines affect the ear. Vibrations cause a bending of the ear’s sensory hairs. The inner hair cells are connected to auditory (type I) nerve fibers that send signals to the brain. You “hear” with your inner hair cells. Inner (IHC) and outer (OHC) hair cells respond differently as sound frequency is changed.
