3D sound field can be recorded using the method of Ambisonics. According to the vertices of Plato's polyhedrons, it is not possible to uniformly distribute arbitrary number of microphones on the sphere except five particular cases. Here we proposed a physical model to solve this problem. In this model, the microphones are assumed to be the charged particles that will move on the spherical surface according to the resultant force by other microphones. After several iteration times, the microphones will be at the equilibrium state, which means that they are distributed nearly uniformly. The emulation experiments were carried on for the 4th order of Ambisonics. The orthonormality errors of each number of the microphones were calculated and the results indicated that the proposed microphone arrangement method performs similar to the penatki-dodecahedron method when the microphone number is 32, but it can nearly uniformly distribute any number of microphones. |
