Three closely connected areas of violin acoustics are studied. They all strive to enhance our understanding of the transient behavior and lack of exact periodicity of musical notes played on bowed strong instruments. Of particular importance is the dynamics of the bow and the related issues of transients and responsiveness of the violin to the bow. The investigation uses both computer analysis and an experimental apparatus to achieve these goals. Collaborations with Dr. J. Woodhouse of Cambridge University and the use of the Pittsburgh Supercomputer Center support the investigation.

研究了小提琴声学的三个紧密相连的领域。他们都努力提高我们对弓形强音乐器演奏的音符的瞬变行为和缺乏确切周期性的理解。特别重要的是弓的动态以及相关的问题，如瞬变和小提琴对弓的反应。这项研究同时使用了计算机分析和实验设备来实现这些目标。与剑桥大学J·伍德豪斯博士的合作以及匹兹堡超级计算机中心的使用支持了这项研究。
