Sound, Few things you should know

Alot of people would describe sound as something any abled person can hear. But the thing
is, sound is more than something practically everybody can hear. It travels in waves, which can be called sound waves.
  Sound is a form of wave motion which is conveyed  through an elastic medium from a vibrating body to a listener. Sound is also  form of energy which travels in such a way that its direction of motion is parallel  to the direction of oscillation of the molecules of the medium.

  For sound to travel in waves, it needs a medium to assist its transmission. This brings us to these media and how fast sound is transmitted through them. Gases, liquids, and solids can assist the transmission of sound waves, but a vacuum can not. For sound to be transmitted to a listener, it requires a material medium.
   The speed of sound depends on the density and elasticity of the material medium at which it travels through.
Scientists have studied sound and have come to a conclusion that sound waves travel at 340m/s at 0° C and in water, at 1500m/s. The speed of sound tends to vary atimes, due to the intervention of factors like wind, temperature of the transmitting medium, humidity etc. In air, the speed of sound increases by about 0.6m/s for every 1% rise in temperature. Wind also as a factor, may decrease the speed of sound if moving at an opposite direction and may increase the speed of sound if it moves in the same direction.
   But there's something you should keep in mind. Moving at such high speed would bring in a phenomenon if attempted by humans or any mass contained objects at all.
   You ever heard of a Sonic Boom? Well if you haven't, stick with me.
Sonic Boom
This is the name given to the phenomenon which occurs when an object breaks the sound barrier in any medium I.e move faster than the speed of sound.
   Nowadays, jet planes travel at amazing speeds. Some, such as the Concorde jet, can zoom faster than the speed of sound. These aircrafts are called Supersonic. They are also calls SST's, or SuperSonic Transports.
   As they fly through the sky, jets make huge amounts of noise. The noise travels through the air to all directions as sound waves. Sonic Boom is a tremendous, thunder-like sound in the sky that occurs when an object moves faster than the sound it produces or any sound at all.
   The waves that go forward travels only a little than their source, the jet. The waves pile up to make a "shockwave" that is like a wall. This is often called the sound barrier.
   If a jet is travelling at the speed of sound or faster, it catches up with its own sound waves. At this point, something astonishing happens. The jet breaks the sound wall and creates a loud bang called a Sonic Boom.
  Sonic Booms can shake houses and rattle windows and plates. That is how strong they are. Sonic Booms can also travel for many miles through the air before they reach the ground.
   So, that's it people, now you are familiar with a few things as regards sound. Take your time to share our articles with yours friends. Thanks for reading, stay tuned for more
