A tuning fork is an acoustic resonator in the form of a two-pronged fork. It resonates at a specific constant pitch when set vibrating by striking it against a surface or with an object. Metal tuning forks are never 100% accurate, and they lose accuracy over time. This makes these audio files more reliable for accuracy.
