When the tuning fork is struck it is easier to tune other instruments with its pure tone.
Broadcasts by radio and television transmitters, and the sounds produced by electronic beepers and video games are the most popular tone generators.
Their resonance is presumably the furthest thing from a pure sine wave at the fundamental frequency than was heard before.
Our unconscious sweet spots occur not only in mechanical systems but also in dynamic systems in virtually every area: for example the beating human heart, vibrating strings in musical instruments, and periodic firing of nerve cells in the brain.
Let this exhibition celebrate these rhythmic outputs.
