1. The problem statement, all variables and given/known data
I have a bit of a problem in class. I am attempting to do an assignment on sound in relation to a guitar. For this I need to explain how the guitar is a highly energetic intrument. I do not know if looking at is like a helmholtz resonator is a waste of my time or not but I'm curious. I, firstly, would like to know if this can relate to how energetic the instrument really is and secondly how it does indeed act like a helmholtz resonator.

I have looked on the internet and in books but I have no found a satisfying explanation. A use of the helmholtz equation in relation to my problem would prove highly beneficial. Any help is highly appreciated and furthermore, any suggestions into anything else i should look at would also be highly appreciated.

2. Relevant equations
f=c/2π √(S/VL)

The main source of sound on an acoustic guitar is the sound board, which is driven by the vibration of the strings at the bridge on the soundboard. I don't think this would qualify as being a helmholtz resonator.
