During the summer of 2007 our
team of one professor and four undergraduate students from Berea
College in Berea, Kentucky worked together to try to better understand
the acoustical properties of stringed instruments and the ways in
which they are tested. Through our work with the three most common
testing methods, Chladni testing, deflection tuning, and tap tuning,
we sought to produce quantifiable data which could be used to search
for correlations between these three testing methods. To do this
we first built test equipment and then built a total of six acoustic
guitars which we tested throughout every step of the construction
process. We have set up this site so that anyone can pull up the
test result pages side by side and be able to easily compare and
contrast the results of each test method at each step of construction.
We are currently working on running the same tests on a pair of
jumbo guitars and will post the results from those test shortly.
