Introduction:

Humans and animals can produce sound and use it to communicate. Many objects can also produce sounds when hit or rubbed against each other. Sound produced by the objects can also be used to identify the type of material used in production of that object. For example that if you see a clear jar and you are wondering if it is plastic or glass, you knock on it and listen to it's sound. Sound has many medical and industrial applications as well. Sounds is used in the sea to locate and identify submarines, fishes and under water elevations.

What is sound

Sound is a physical entity, that unlike noise which is the perception of sound. Sound is a high pressure wave front through a medium (such as air, or a liquid such as water, or a solid), wherein the wave front is followed by a reciprocal pressure differential behind it. Sound is produced when something disturbs the medium and sets in motion the molecules in the medium.

How is sound produced?

When sound vibrations are more, they push our particles like your hands would push a slinky. Vibrations cause area ...

Frequently, (no pun intended) the wave is front/reciprocal entity occurs as an oscillating wave, wherein there are a series of wave fronts (peaks in pressure), followed by wave valleys (lower pressure). The relatives height of the peak translates to how much energy is in the wave (how great is the pressure), and the closeness of peak to peak (spatially and temporally) indicates the pitch.

Noise, is cannot a physical entity, but is the mental perception of the physiological response to sound. A wave front is converted from the mechanical energy in our ear into an electrical impulse in the brain that analyzes the wave information. The interpretation of the wave front is a subjective and the brain may interpret the wave signature as speech, music, clapping, gunshot, hum, etc.
