I use my finger for excitation of the violins I measure. The fingernail gives some highfrequency resonse, but most of the energy in the impulse is probably in the low frequency region. That gives an underestiamtion of the high frequency response of the violins.
Do you have an idea how to compensate for the frequency dependent excitaion signal in a simple way? Would it improve the frequency response to use an compensation from measuring impulses directly by excitating the microphone several times and use the average frequency response of that signal to correct the measured responses of the violins?
