BIOGRAPHICAL PROFILE
Acoustic guitar
An acoustic guitar is a guitar that uses only acoustic methods to project the sound produced by its strings. The term is a retronym, coined after the advent of electric guitars, which rely on electronic amplification to make their sound audible.
In all types of guitars the sound is produced by the vibration of the strings. However, because the string can only displace a small amount of air, the volume of the sound needs to be increased in order to be heard.
In an acoustic guitar, this is accomplished by using a soundboard and a resonant cavity, the sound box. The body of the guitar is hollow.
The vibrating strings drive the soundboard through the bridge, making it vibrate.
The soundboard has a larger surface area and thus displaces a larger volume of air, producing a much louder sound than the strings alone.
Amplification:
Many acoustic guitars incorporate rosettes around the sound hole.An acoustic guitar can be amplified by using various types of pickups or microphones.
The most common type of pickups used for acoustic guitar amplification are piezo and magnetic pickups.
Piezo pickups are generally mounted under the bridge saddle of the acoustic guitar and can be plugged into a mixer or amplifier.
Magnetic pickups are generally mounted in the sound hole of the acoustic guitar and are very similar to those found in electric guitars.
Historical and modern acoustic guitars are extremely varied in their design and construction, far more so than electric guitars. Some of the most important varieties are the classical guitar (nylon-stringed), steel-string acoustic guitar and lap steel guitar.
