What is the sound generator?

The sound generator is an object that makes sounds. These sounds can be produced by an almost infinite number of ways, from stom to floor to floor to siren of the fire engine. Regardless of the origin of the sound, it is always the same - vibration in the air that creates a formula with recognizable hearing senses. While the ways to develop sound are almost unlimited, virtually all the sounds generating the sounds fall into two main categories: unity-ton and more tones. Each of these processes creates a full and complete sound pattern, but in different ways. The sound

may seem like many different things, because the mewing and cutting of grass seems so different - but it is not. The sound is simply vibration moving through the air from the sound generator, such as the lawn, to the auditory receptor like the human ear. These vibrations actually disrupt the air itself, which generally means that if there is no air, then there is also no sound.

When the sound generator works, the way it disrupts the air determines how it is fromof it. Large, violent disruptions become great and violent sounds. As the generator works, it creates a wave of energy that causes disturbance. As the wave moves further from the object, it is equal until the energy is no longer disturbed. This causes a reduction in volume and slower repetition above the distance, and therefore the siren gets in a disproportionately louder, higher and faster, the closer it to the source.

There are two basic forms of sound generator: a one -time generator and a multi -tone generator. One tone generator works through a fixed interaction between two objects. When one object interacts with the other, the sound is released and the sound is the only sound available for this interaction. A good example of this type of generator is the xylophone rod; Strike at the bar results in one note that does not differ in creation. As the wave moves through the air, there may be some variations, but it is independent of the sound generator.

Multi-tone generator may actually differ as it is produced. INIn this case, when the sound is released, one or more parts of the generator are variable. This allows tone sound change and can lead to a warbling effect that one tone generators cannot produce. A common example is the tube; The user can change the amount and speed of air flow by changing the shape of its lips while playing a continuous note.
