How do tuning forks work

In the 19th century, advances in manufacturing made it possible to create extremely precise tuning forks, which were made in sets and used as tone generators to identify and measure other sounds. By the last decades of the 19th century, tuning forks were among the most precise of all scientific instruments. Specialized techniques were developed to use them for measuring different kinds of vibrations, and they were frequently used as high-precision timing standards.

Albert Michelson, for example, used light reflected from the vibrating tines of a tuning fork to make his historic measurements of the speed of light. In the 20th century, the development of electronic technologies for measurement and precision timing quickly replaced technologies that employed mechanical tuning forks.

One notable exception has been the introduction, around , of tiny quartz tuning forks in high-precision watches. Maintained in motion by batteries, the resonating forks far exceed the accuracy of conventional mechanical watches.

The tuning forks were each milled from a single blank of fine steel and were then precisely tuned to produce a single, specific, tone. The resonator boxes that they are bolted to are wood, made from the same spruce often used in stringed musical instruments. Spruce wood is naturally responsive to sound vibrations and is the ideal material for this application. Beats are produced when two similar sounds interact. Using a stopwatch, the doctor will time how long the patient can hear it by the skull and the ear.

If the patient feels the fork more through the jaw than they can hear it through the ear there is a problem conducting soundwaves. In addition to hearing loss, the tuning fork can be used to evaluate a wide range of other health problems. If X-rays are in short supply, doctors will use tuning forks to identify whether a bone is fractured or not. Doctors do this by simply striking a tuning fork and placing the vibrating fork close to the affected area.

Tuning forks can also provide sound therapy which helps induce a deeper state of relaxation. Using a tuning fork for sound therapy is one of the best techniques to achieve total relaxation. The tuning fork is a great and non-invasive healing tool.

It can used for several healing and evaluation practices including: Rinne tests, X-rays and sound therapy. Air molecules are continuously vibrating back and forth about their original position. There is no net displacement of the air molecules. The molecules of air are only temporarily disturbed from their rest position; they always return to their original position. In this sense, a sound wave like any wave is a phenomenon which transports energy from one location to another without transporting matter.
