GMC Forum _ CHILL OUT _ Aucustic Instruments

Posted by: erik Apr 2 2008, 12:47 PM

Hey, I'm having a school project where I'm supposed to explain how aucustic instruments work. If someone is good at this, can you explain a little? For example, how does the shape of the instrument make the spesific sound for that instrument?

Anything you know about it, and don't be afriaid of going into detail. I'm supposed to explain the physics of it as well (like with wavelength of the sound with frequenzy etc.)

well if you mean acoustic like a big hollow thing.
i guess if the initial vibration is given out by a bigger body it will allow more waves to like come out if you get what i mean. and if its hollow, that is the surface area of the outside X2 and it will be comming out of a sound hole which is facing "that" way so it will sound louder the direction the sound hole is facing...
correct me if i am wrong (probably. but its logical in my little brain)

No idea, but this looks promising:

Well, the bigger the resonance box is , the deeper the sound.

The larger the top of the guitar is, the more the sound is projected. Also deeper body etc.
