Resonant Rings consists of circular steel bands of various diameters that are mounted on a plate which has been attached to a loudspeaker. By adjusting the frequency of the sound from an oscillator to the speaker, a graphic illustration of harmonic resonance can be seen in the rings as they vibrate at various frequencies and in different modes. The frequency of the speaker can be read directly on a digital counter. Exciter levers are provided for two of the rings so they may be struck lightly and their “natural frequency” observed, or their motions dampened.
