![]() ![]() At higher frequencies the dynamic behaviour of the bridge produces additional formant-like features, reminiscent of the “bridge hill” of the violin, and these also produce clear perceptual effects. ![]() A formant-like feature, peaking around 500–800 Hz on the banjo tested, is found to play a key role. Recognisable banjo sound seems to depend on the pattern of decay rates of “string modes”, the loudness magnitude and profile, and a transient contribution to each played note from the “body modes”. A synthesis model, fine-tuned using information from the measurements, has been used to investigate what acoustical features are necessary to produce recognisable banjo-like sound, and to explore the perceptual salience of a wide range of design modifications. ![]() ![]() ** Corresponding author: of vibrational response of an American 5-string banjo and of the sounds of played notes on the instrument are presented, and contrasted with corresponding results for a steel-string guitar. It lets you create Chladni frequency patterns without the expense of traditional hardware needed for plate vibration research. The classical Chladni experiment is carried out on a plate with free boundary conditions.
