here first results of acoustic measurements are presented.
the guitar was tuned in open D, strings are damped while taking the measurements.
first of all, the acoustic input admittance is measured by attaching a accelerometer onto the bridge while the excitation was done whith an impact hammer.
not being able to present a interpretation in first place,
the input admittance curve is shown in the next pic:
second measurement takes place in an anechoic chamber, excitation with a mini shaker, measurement of excitation force and acceleration.
vibration analysis of body and cone
more to come....
