If you want to know what it is and which mechanism generates and transmits it, keep reading.<\/p>\n<p>The sound is a <strong>physical phenomenon<\/strong> that occurs when the <strong>vibrations of a transmitter body<\/strong> pass through a fluid or an elastic medium, and then they are perceived by the ear or any other receiver. An elastic medium can be air, water or solid materials such as iron, plastic or copper.<\/p>\n<p><strong>The science of acoustics study both sound itself and all the phenomena<\/strong> associated with it (its propagation, its properties and its generation). Acoustics can adopt two different perspectives:<\/p>\n<ul>\n<li>The acoustics that studies <strong>sound as a physical phenomenon<\/strong>, that is, as the mechanical vibration that causes a stimulus to produce an auditory sensation.<\/li>\n<li>The acoustics that studies <strong>sound as a physiological phenomenon<\/strong>, that is, as the auditory sensation that causes the mechanical vibration.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h3>How is sound produced<\/h3>\n<p>Therefore, three elements come into play in the phenomenon of sound: <strong>the transmitter, the transmission medium and the receiver<\/strong>. The sound is generated when the vibration caused by the emitter is propagated through a medium (air, water, etcetera) to end up reaching the receiver.<\/p>\n<p>It should be noted that <strong>sound can not propagate in a vacuum<\/strong> as light does: sound waves need a physical medium in which they can travel from the transmitter to the receiver.<\/p>\n<p>A piano, a guitar, a speaker or a person\u2019s vocal cords are examples of a <strong>sound source<\/strong> (the element that generates sound when vibrating). This vibration is transmitted to nearby air particles that also transmit it to the adjacent particles by an oscillating movement. This is <strong>how the sound wave propagates<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Music, voices, public address messages&#8230; what they all have in common is sound.
