What is Sound Energy?
Energy, or the general capacity for work to occur, can come in several forms. Energy is presently known to exist in several forms, such as heat, light, chemical, mechanical, and so forth. One of the many forms of energy is sound energy.
In contrast to other forms of energy, the energy of sound occurs when mechanical energy is transmitted in the form of vibrations over a solid, liquid or gas medium. It is generally measured by the vibratory waves it produces and is observable in the same manner. In environments where no medium exists, such as the vacuum of space, no sound energy can be transmitted nor oscillated.
Sound Energy and Frequencies
The vibratory waves that travel via the medium are, in general, the result of different oscillating pressures. The rate at which these pressures are transmitted at in relation to time determines the frequency of the sound.
The frequency of sound energy and wavelength of the sound over a particular unit of time is measured in Hertz. The unit Hertz is thusly used to determine the general strength of the energy produced, and the capacity of energy to be perceived and to cause vibration in materials and media. Depending on the medium it is transferred through, the inherent motion of the medium and the density and pressure of the environment, the frequency of sound energy can be manipulated.
Sound Energy and Perception
Many animals, including human beings, utilize sound as part of the sense periphery. Many creatures use distinctive sounds for communication and warnings. Almost every activity or phenomenon within the atmosphere of the planet creates sound, and most sentient beings use their perception of the sound energy produced to determine the nature of the action and the possible threat it may hold.
Human beings, for example, have a sound perception of frequencies ranging from 20 Hertz to 20,000 Hertz. Other animals, such as whales and dogs, have a broader range of sound perception.
Sound Energy and Material Oscillation
While most sound energy is generally non-destructive and often unnoticed by all but the most advanced of sound equipment, it may also become a powerful and destructive force under high frequencies. Trained opera singers have been known to be able to produce high frequency sound energy that strong enough to shatter glass.
Under unusual circumstances, bridges and buildings can be destroyed by sound frequencies, which resonate with the construction materials and create oscillations within the material. If the force generated by the energy is strong enough, this can lead to the disintegration or breakdown of the materials and component.
