In the violin, the fundamental air cavity mode (the A0 mode) is associated with the sound radiated by the f-holes. The dependences of the sound velocity of the A0 frequency on gaseous temperature and mass were investigated. It was found that the frequency of the A0 mode changed, depending on the molecular weight and the temperature of the gas filling the violin’s body. From these results, it was deduced that a temperature change in the room in which musical instruments are played may be reflected in their tones. The measurement of the A0 modal frequency of a violin, focusing on the molecular weight and temperature of the gas, would be useful to students of physics to help in the understanding of sound velocity.

在小提琴中，基本的气腔模式（A0 模式）与 f 孔辐射的声音有关。研究了 A0 频率的声速对气体温度和质量的依赖性。发现 A0 模式的频率会发生变化，这取决于填充小提琴主体的气体的分子量和温度。从这些结果推断，演奏乐器的房间内的温度变化可能会反映在它们的音调上。小提琴的 A0 模态频率的测量，重点是气体的分子量和温度，对于物理专业的学生有助于理解声速。
