get heavier gauge strings, than you can make it sound much louder
the larger the amplitude at which something vibrates = the louder the sound. so by plucking a string harder, you're increasing the amplitude of the sound waves and thus increasing the sound volume
When it is on the guitar, the vibrating string makes the guitar vibrate with it.
The larger vibrations induce a greater magnetic field.
When mounted on an acoustic guitar the body serves as a soundboard to amplify the vibration of the strings. On a unplugged solidbody electric guitar you will notice that the sound is very similar to the string mounted to the workbench.
there is a hole in the guitar because it helps make the sound louder.
The guitar makes sound when you pluck a string. The string vibrates down to the base of the guitar and travels in the hole, coming out as a sound we call a note.
The sound becomes brighter when strings are plucked and only seems to be louder.
Plucking harder puts more energy into the string's movement, so it moves with a bigger amplitude, producing a louder sound.
The sound is produced by the vibration of the string.
An acoustic guitar is hollow, with a sound hole, allowing it the reverberate the sound, and making it louder. An acoustic guitar is always louder than an electric. (When the electric has no amp.) Acoustic is hollow allowing the sound to reflect off the inside and echo producing louder sound waves. (Like an auditorium.) whereas the electric is hard below the strings preventing any echo.
The string makes the sound by transferring it's vibration to the top of the guitar. The top vibrates, and that is amplified by the body of the guitar. The round hole is to let that sound escape.
