This week I take four sopranos to our luthier school and try to research their differences by metering. I have one Martin S0 from -62, one diligently played Mexican made Martin S1 from 5 years ago, one Ken Timms cuban mahogany that I bought about year and half ago.
For comparison I have also 3 years old John F Kinnard soprano, which was bigger body, side sound port, different bracing and cedar top and mahogany back and sides.
First I weighed them. Then meter top and back frequencys with open and closed sound hole. I did every metering 10 times and calculater avarage values. Who guess results? Did they differ much?
Then I took them to our zero acustics room (an anxious and unpleasant place) and record their voices. I haven't done it yet, but I will try to analyze their voices using spectrogram software and learn something. Or maybe I just did this for fun and curisity. I want to find out what can I meter and is it useful to me as a luthier. I have read some academic thesis about metering instruments voice quality using technical tools and computers, but usually all scientific research and the instruments studied have been other than ukuleles, typically violins.
Old way is exact measures, taptuning and listening, but I want to try this. And then I go back to taptuning, becouse I belive it will never goes out of fashion.
