The acoustic properties of the banjo have been subjected to very little scientific study. The few studies that exist have used the five-string banjo. Dickey (2003) used a structural dynamics model to simulate the effects of features such as loss factor, head tension, bridge mass, and string excitation location on qualities such as loudness, brightness, and sound decay. He showed that his model predictions agreed well with accepted banjo setup practices. Rae and Rossing (2004) published some of the first performance data obtained from sound and vibration measurements from real banjos. Stephey and Moore studied banjo bridge impedance and head motion using electronic speckle pattern interferometry (2008).
