http://www.physicsinfo.co.uk/?page=view&id=2570 WebPerception of infrasound. Infrasound is sound at frequencies lower than the low frequency end of human hearing threshold at 20 Hz. It is known, however, that humans can perceive sounds below this frequency at very high pressure levels. [1] Infrasound can come from many natural as well as man-made sources, including weather patterns, topographic ...
WebWhen travelling through air, the speed of sound is about 330 metres per second (m/s). Sound cannot travel through a vacuum because there are no particles to carry the … WebWhen a wave passes through a denser medium, it goes faster than it does through a less-dense medium. This means that sound travels faster through water than through air, and faster through bone than through water. When molecules in a medium vibrate, they can move back and forth or up and down.
