Tuning forkOwing to advances in electronics, tuning forks are rarely used in experiments nowadays. The pictured tuning fork is a variable-pitch model, allowing any desired pitch to be produced by simply moving the screw-mounted weights up or down along the tines. The origins of the tuning fork can be traced back to one invented in 1711 by John Shore, a trumpeter who served the British court. The tuning fork allows pure sounds at specific frequencies to be produced with ease, and, since its invention, has been used for a wide range of purposes: to tune instruments, for hearing tests, for vibration perception tests, and as an experimental tool for demonstrating resonance phenomena in physics classes The tuning fork has played a central role in the history of acoustics. Due to its small size and high portability, ease of handling, durability, and reliability, the tuning fork remains a tool beloved by musicians even to this day. Exquisite examples like this one can also be appre-ciated as valuable works of art.Owned by the Museum for the Science of Sound, Kobayasi Institute of Physical ResearchCourtesy of the Museum for the Science of Sound, Kobayasi Institute of Physical ResearchPhoto by Yuki AkabaThe Evolving World of Acoustics and Vibration TechnologiesThe World of Acoustics
