Acoustic Guitar

The body of the acoustic guitar is hollow and does not have electric amplification. Its name is a retronym of the electric guitar to differentiate them from each other. The top plate could be made of cedar or spruce while its strings could be made of steel or nylon. At the top is a circular hole with a diameter of 3.25 inches to 3.5 inches which strengthens and reinforces the produced sound.

Sound production

Sound is typically produced on guitars through the strings' vibration. The increase of volume is done by the sound box consisting of a resonant cavity and a soundboard. The vibration of the strings also causes vibration of the soundboard. It has a much larger area than the strings which means that is also produces a louder sound.

Sound waves are created coming from the back and front panels as the soundboard is vibrating. The sound box serves as a resonant cavity and reflects the sound waves produced. The sound volume increases greatly compared to the primary volume created by the strings. Some sound is then projected out of the hole.
