  • Resonator cases with tuning forks produce a louder tone with a greater range of audible overtones. You can provide an interesting demonstration of sympathetic vibration.
  • Sympathetic Vibration demonstration – Place two resonance cases of the same size, shape, and construction near each other; a vibration exists only in one fork, the other case, and the tuning fork will begin to vibrate sympathetically.
