柯氏音是在麻醉的狗中产生的，并进行了详细研究。通过荧光电影技术显示血流模式的变化。各种机制产生Korotkoff声音进行了讨论。已经证明，心音和柯氏音是不同的和独立的实体，因为它们在时间上是可分离的，并且通过改变感测元件的位置而受到不同的影响。这些实验表明，湍流发生在流动（对应于Korotkoff声音），尽管事实上，计算的雷诺数低。柯氏音的产生不需要血管壁。
Korotkoff sounds were produced in anesthetized dogs and studied in detail. The change in the pattern of blood flow was demonstrated by cinefluorographic technique. Various mechanisms producing Korotkoff sounds are discussed. It was demonstrated that heart sounds and Korotkoff sounds are distinct and separate entities since they are separable in time and are differently influenced by changing the site of the sensing element. These experiments demonstrate that turbulence occurred in flow (corresponding with Korotkoff sounds) despite the fact that the calculated Reynolds numbers were low. The vessel wall is not necessary to the production of Korotkoff sounds.
