Tuning fork Definition and 5 Discussions

A tuning fork is an acoustic resonator in the form of a two-pronged fork with the prongs (tines) formed from a U-shaped bar of elastic metal (usually steel). It resonates at a specific constant pitch when set vibrating by striking it against a surface or with an object, and emits a pure musical tone once the high overtones fade out. A tuning fork's pitch depends on the length and mass of the two prongs. They are traditional sources of standard pitch for tuning musical instruments.
The tuning fork was invented in 1711 by British musician John Shore, Sergeant trumpeter and lutenist to the court.

    I Help Designing a Resonance Box for Tuning Forks

    I got these tuning forks from someone. However, I do not have the resonant box for amplification of the sound. I decided to get it made so that I can experience the fundamental frequency (and other harmonics) more clearly. I am planning to provide this design. In summary, the box would be...

    Helmholtz synthesizer experiment

    Hello all! Inspired by the Helmholtz synthesizer, I am experimenting with electromagnetic excitation and tuning forks. http://www.sites.hps.cam.ac.uk/whipple/explore/acoustics/hermanvonhelmholtz/helmholtzssynthesizer/ How can I determine the size and charge of an electromagnet in order to...

    How to find the wavelength of the sound of the tuning fork?

    Homework Statement 1) find the wavelength of the sound of the tuning fork (cm) 2) what's the vertical distance x from the top of the pipe to the antinode above the pipe (cm) 3) find the frequency of the tuning fork (Hz) Homework Equations velocity = wavelength . frequency for pipe closed at...

    A problem on tuning fork.

    Homework Statement 2 tuning forks A and B, when sounded together produce 4 beats. when B is loaded with wax, the beat frequency remains same. if frequency of A is 212 Hz, then frequency of B is? Homework Equations The Attempt at a Solution since the beat frequency is 4 and frequency of A is...

    Resonance and Damping

    Homework Statement I was doing a question about resonance of sound box connecting to a tuning fork. It asks why the sound lasts for a shorter time with sound box than if the tuning fork is struck identically without the sound box. Homework Equations The Attempt at a Solution Is it because...
