used to produce sound. Sound is an energy which is created by passing through a gas or liquid medium. Sound is measured in Frequency and Decibels. Decibels is how loud the sound being produced is‚ the frequency is the quality of the sound that has been produced. Speakers can produce a range of sounds

is a lot of physics behind the creation of it‚ from the strings to the air inside‚ the anatomy‚ and the sound spectrum. There are three types of guitars that are made: nylon acoustic‚ steel-string‚ and electric. Acoustic guitars produce sound due to a complicated interaction called coupling. Coupling refers to the interaction between two or more vibrating elements. It depends on geometry‚ sound frequency‚ and the materials that are used to make it. There are 3 parts to how a guitar works: the strings
