What Is The Sound Energy?

How is a sound created? It is actually simple. The sound is made by the air vibrating. These vibrations of the air are called waves. The number of times that a sound wave vibrates is called its frequency. We even have a measure for the frequency. The name of the measure is hertz. And as all things that move, the sound also has energy. Incredible as it may seem, the existence of sound energy can be easily proved.

There are simple ways to feel the energy of sound. For example, when someone plays the guitar, he generates sound energy. Just put your hands on the guitar and you will feel the wood vibrating. Another simple example uses a fork. Take a fork and strike it against the table. Then, put it on your year, and you will hear and feel the vibrations. This is possible due to the motion of the molecules, found all around an object. Without them, there would be no vibration at all. When those molecules move, they create compression areas (areas with many molecules together) and rarefactions (when molecules are spread apart). These areas move away from that object, in circles, creating a wave through the air. The distance between the sound waves is the so called wavelength. The wavelength depends on how fast the sound waves travel through the air. The vibrations can also bring the molecules together. This process is called the amplitude of the sound. So, if an object is pushed harder to vibrate, the sound will be louder (or the amplitude greater).

Like all the other sources of energy, the sound energy can also be converted into other forms of energy that we can use. Also, there some types of energy that can be transformed into sound energy. To obtain electricity from the sound energy we use the oscilloscope. This machine helps us see the sound waves. The oscilloscope uses high technology that allows us to see the voltage of an electrical signal.

And, we use sound energy every day without even knowing it, by the simple use of the telephone. The phone has the technology required to convert sound energy into electrical energy and vice versa.

With the help of a transmitter, a receiver and a dial button, we can talk to people all around the world. The telephone picks up the signals and notifies the central office. Also, the phone has to "translate" the electrical signal. The process is not simple, but most important is that there is use for the sound energy.
