Pressure Radiation

This section describes two radiation models for the guitar. In the first approach, the sound pressure is synthesized at any number of virtual microphone positions by means of a simplified Kirchhoff-Helmholtz integral over the radiating surfaces determined by the modal state [29]. The second approach is a simplified point-to-point method which uses recorded input/output signals to compute a transfer function between the string-bridge junction to the position of the output-recording microphone.
