Web17 jan. 2024 · Sound waves basically travel by vibrating the particles in a medium, i.e., molecules of air. These vibrations are passed on to consecutive particles in the medium, meaning that sound waves cannot travel without a medium. The reason we can’t hear sound in the space is typically due to a lack of such a medium. Web16 mrt. 2024 · Volcanoes rumble, waterfalls crash, and air rushes, but there’s more to that sound than what our ears perceive. Much like how infrared light consists of frequencies that aren’t visible to the naked eye, there’s an audio analogue called infrasound. Infrasound consists of pitches too low to be heard by the human ear, between 0.001 and 20 hertz.

Ultrasound and infrasound Sound: A Very Short Introduction

WebSound is a mechanical wave that results from the back and forth vibration of the particles of the medium through which the sound wave is moving. If a sound wave is moving from left to right through air, then particles of air will be displaced both rightward and leftward as the energy of the sound wave passes through it.
