Estimation of the Radiation Pattern of a Violin During the Performance Using Plenacoustic Methods

We propose a method for estimating the 3D radiation pattern of violins, during the performance of a musician. A rectangular array of 32 microphones is adopted for measuring the energy radiated by the violin in the observed directions. In order to gather measurements from all the 3D angular directions, the musician is free to move and rotate in front of the array. The position and orientation of the violin is estimated through a tracking system. As the adopted hardware is very compact and non-invasive, the musician plays in a natural fashion, thus replicating the radiation conditions of a real scenario. The experimental results prove the accuracy and the effectiveness of the method.
