4/6/2023 0 Comments Soundwaves![]() ![]() When the air borne sound waves change mediums, the sound wave will undergo certain characteristics. ![]() Now let’s place a barrier in front of the sound source. Sound waves are energy transfers through molecules in the same manner as billiards balls collect and transfer stored energy. In a perfect rack, the center 8 ball should not move as the perimeter balls scatter across the table. The energy will transfer from ball to ball via structure borne vibration. A tightly racked set of billiards balls will mirror sound wave activity when the cue ball strikes the front ball in the rack. As a sound vibration is produced, the fluctuations are passed through any of these mediums transferring energy from one particle of the medium to its neighboring particles, much like doing a “wave” at a sporting event.Ī good example of this energy transfer can be tested on a billiards table. Air, steel, concrete, wood, water, and metal are all made of molecular structure. Sound waves are actually organized vibrations that pass from molecule to molecule through most any medium. As our first illustration shows, these invisible waves pass over distance and time cycling above and below the atmospheric pressure line.īut in fact, sound waves really aren’t waves at all. These fluctuations are called sound waves. From a dog’s bark to a referee’s whistle, from a baby’s cry to a rock concert, the sound we hear is caused by vibrations that create fluctuations in the atmosphere much like a tuning fork will produce. Every sound we hear is the result of a sound source that has induced a vibration. Let’s start with a basic understanding of the sound wave. ![]()
