A leading musical instrument company decided to enter the drumstick market. While wood is a great material for drumsticks, it’s non-uniform. To compete in the drumstick marketplace, our customer needed to precisely match sticks for weight, pitch and balance. This machine weighs a stick at both ends, finds the balance point, and taps it repeatedly with a soft rubber hammer, performing a fast fourier transform to evaluate the fundamental (lowest) frequency of the stick. Sticks are distributed to thirty-six bins, each having an “A” and a “B”. Drummers have 72 different stick classes to choose from, and by sticking with a single class, can be confident that every stick feels, sounds and plays the same.
