A Statistical Approach to Violin Evaluation

Comparing violins requires competence and involves both subjective objective evaluations. In this manuscript, vibration tests were performed on a set of 25 violins, historical new. The resulting bridge admittances modeled in the low mid-frequency ranges through features. Once projected into new representation, three made by Stradivari famous reproduction revealed high similarity. PCA highlighted importance signature mode frequencies, hill behavior, amplitudes distinguishing different violins.
