由Cremonese大师安东尼奥·斯特拉迪瓦里和朱塞佩·瓜尔内里·德尔·格苏创作的古典小提琴，已经成为所有小提琴声音在表现力和投射能力方面进行比较的基准。人们普遍认为，从那时起，没有哪个琵琶手能够复制这些古典乐器的音质。小提琴的振动和声辐射特性由乐器的几何形状和木材的材料特性决定。新的测试方法允许在生长轮细节级别对关键材料特性之一的木材密度进行无损检测。使用计算机断层扫描和专门开发的图像处理软件，比较了五把古典小提琴和八把现代小提琴的密度。现代小提琴和古董小提琴的密度中值之间没有显著差异，但在顶板(云杉)和后板(枫叶)中，古典克雷蒙尼小提琴生长早期和后期的木纹密度差异明显小于现代小提琴(p = 0.028和0.008)。现代小提琴和古典小提琴顶板的平均密度差分别为274(26.6)克/升和183(11.7)克/升。对于背板，其值为128(2.6)克/升和115(2.0)克/升。密度差的这些差异可能反映了刚度分布的类似变化，这可能直接影响振动效率或通过改变阻尼特性间接影响声辐射。这些机制中的任何一种都可能有助于解释古典小提琴和现代小提琴之间的声学差异。
Classical violins created by Cremonese masters, such as Antonio Stradivari and Giuseppe Guarneri Del Gesu, have become the benchmark to which the sound of all violins are compared in terms of their abilities of expressiveness and projection. By general consensus, no luthier since that time has been able to replicate the sound quality of these classical instruments. The vibration and sound radiation characteristics of a violin are determined by an instrument's geometry and the material properties of the wood. New test methods allow the non-destructive examination of one of the key material properties, the wood density, at the growth ring level of detail. The densities of five classical and eight modern violins were compared, using computed tomography and specially developed image-processing software. No significant differences were found between the median densities of the modern and the antique violins, however the density difference between wood grains of early and late growth was significantly smaller in the classical Cremonese violins compared with modern violins, in both the top (Spruce) and back (Maple) plates (p = 0.028 and 0.008, respectively). The mean density differential (SE) of the top plates of the modern and classical violins was 274 (26.6) and 183 (11.7) gram/liter. For the back plates, the values were 128 (2.6) and 115 (2.0) gram/liter. These differences in density differentials may reflect similar changes in stiffness distributions, which could directly impact vibrational efficacy or indirectly modify sound radiation via altered damping characteristics. Either of these mechanisms may help explain the acoustical differences between the classical and modern violins.
