Acoustics

Acoustics Definitions Is the rapidity in moving, traveling, performing, etc.; swiftness. Also frequence, the state or fact of being frequent; frequent occurrence. The number of cycles or completed alternations per unit time of a wave or oscillation. Is the distance, measured in the direction of propagation of a wave, between two successive points in the wave that are characterized by the same phase of oscillation. Extending in the direction of the length of a thing; lengthwise. (adjective) Lying or extending across or in a cross direction; cross. (noun) something that is transverse.
 * Speed (noun):
 * Frequency (noun):
 * Wavelength (noun):
 * Longitudinal:

Video Sound is not only caused by objects vibrating. Large objects make big waves of vibration, which have a low frequency noise. Small objects make small waves of vibration, which have a high frequency noise. Sound energy gets quieter as it covers more area. Sources of Impulsive Sound: A compression wave of air, for example, can become an acoustic wave. An acceleration noise can also emit an acoustic wave. Sonic Boom: When an object passes through the air it creates a series of pressure waves in front of it and behind it. These waves travel at the speed of sound, and as the speed of the object increases, the waves are forced together, or compressed, because they cannot get out of the way of each other, eventually merging into a single shock wave at the speed of sound, creating an acoustic wave.
