How Guitars Make Sound

Introduction When an object vibrates, the medium directly adjacent to it will cause mechanical interference and produce sound. Sound is a pressure wave traveling through the medium (usually air). The medium then transmits the pressure wave to the human or animal's ear. For example, when you play a guitar string, the string begins to violently vibrate, pressure waves propagate through the medium to the ear, and you hear the sound. Sonic equation is speed = wavelength × frequency.

The normal (original) guitar sounds completely by vibration. When you pull the string, it vibrates back and forth, the energy of the sound is transferred to the hollow wooden body of the guitar, it (and the internal air) resonates (synchronized with the vibration) and the sound is amplified It gets bigger). If you have ever seen electric guitar so far, you will find that most of them have thinner (and sometimes smaller) entities than acoustic guitar. Most electric guitars are made of wood, but the material in which they are made is not important. As George Beauchamp (a pioneer of modern electric guitar) pointed out in the 1930s patent, "Bodies can vary greatly in size, shape and structure, making them without departing from the spirit of the present invention His initial design shows that the body can be made with "simple integral casting of metal like aluminum".

Why is material more important than using an acoustic guitar? The body of an electric guitar is not so important in sound production and amplification, so what you really need to do is to hold the string and tighten it long enough to produce the frequency of the sound we want to listen to . While resonance still plays an important role in giving tones to electric guitars, solid electric guitars create a large part of the sound through a completely different process from acoustic guitar. In fact, it seems that acoustic guitar and electric guitar resemble each other, and even if you play them in roughly the same way, they are completely different instruments.
