音叉的前身是餐叉。餐叉原本是希腊、罗马和日尔曼各部落的厨具,公元1000年左右,意大利宫庭才用来进餐。十六世纪时餐叉还属于奢侈品,到十八世纪才成为普通家庭的日用品。 Giovanni Felippo Ingrassia(1510～1580,意大利解剖学教授)是最早利用餐叉发现骨传导现象的人,也是第一个描述和命名镫骨的人。1546年他发现将振动的餐叉抵于牙齿上可以听到声音,这就是“Ingrassia现象”,也就是骨传导。可惜当时他没有发表这一发现,直到1603年才由他的孙子弥补了这件憾事。因此,人们常常归功于Girolamo Cardano于1550年最早描述了骨传导。第一个认识骨传导诊断意义的人是Hieronymus Capivacci(死于1589年)。100年后,Gunther The fork is the fork fork. The fork was originally a kitchenware of the tribes of Greece, Rome and Germain. The Italian court was used for meals only around 1000 AD. In the 16th century, the fork was also a luxury item, and it became an ordinary household commodity until the eighteenth century. Giovanni Felippo Ingrassia (1510-1580, Professor of Anatomy in Italy) is one of the earliest people to find out the phenomenon of bone conduction with his fork, and also the first person to describe and name stapes. In 1546 he found that vibrating fork can be heard on the teeth of the teeth, which is “Ingrassia phenomenon”, that is, bone conduction. Unfortunately, he did not publish the discovery at that time until 1603, only to make up for the regrettableness by his grandson. Therefore, it is often credited with Girolamo Cardano's earliest description of bone conduction in 1550. The first person to recognize the significance of bone conduction diagnosis was Hieronymus Capivacci (died 1589). 100 years later, Gunther
