The primary methods for us to be heard are through talking, singing and shouting. There are even several gadgets or devices that serve as a medium. These are you television sets, radios and other electronic components around your surroundings.
But the question is, how does the sound reaches the listener?
The world that we are living consists of air and it is where the sound of our voices travels and spread around. As the sound travels through the air, it moves similar to a wave. This wave can be illustrated by imagining that you are on a beach viewing the water that moves back and forth.
The waves compose of tiny movements of air and this is referred as the “vibrations”. We can not see with our naked eyes the presence of a vibration but we can sense it through our sense of hearing or it can be felt.
Some might not believe that vibrations can be felt and to prove this claim let’s have a short experiment.
You will simply need a piece of paper and a companion to help you out. If everything is ready, ask your friend or assistant to shout while use the piece of paper to block the sound. You will notice that the paper will move or vibrate. The bigger the paper you use the larger area of the sound waves are blocked which makes the vibration stronger. I guess that this is good enough as a proof that this invisible force can be felt through a medium.
Our electronics technology today uses sounds especially to inform or alert us where we need to take notice about. Your mobile phone will ring when somebody calls you even during the middle of the night. The same thing goes to your clock when you set it up for a certain time to wake you up. Even the toys are now popularly embedded with electronic components to play sounds which add more entertainment of playing them.
