Bridge admittances (a) vertical at the bridge corner as measured on the Deering banjo (without resonator) (red) and as computed by the FE/BE model (blue); (b) horizontal at the bridge corner as measured (red) and as computed by the FE/BE model (blue); (c) vertical at the third string notch as measured (red) and as computed by the FE/BE model (blue). The vertical dashed lines in (a) and (b) indicate the frequency of the displacement plot in Figure 14a. The vertical dashed line in (c) indicates the frequency of the displacement plot in Figure 14b.
