Technology

What is sound ?
Sound may be defined as any air pressure variation that the human ear can detect. Like dominos, a wave motion is set off when an element sets the nearest particle of air into motion. This motion spreads to adjacent air particles further away from the source. Depending on the medium, sound propagates at different speeds. In air, sound propagates at a speed of approximately 340m/s. In liquids and solids, the propagation velocity is greater - 1500 m/s in water and 5000 m/s in steel.
