Abstract :
A new formulation based on ellipsoid coordinate is proposed to describe acoustic pressure in the acoustic field, which is suitable for reconstructing acoustic pressures field radiated not only from a sphere or an ellipsoid, but also from other sources similar to an ellipsoid, which extends the appropriate application domain of traditional HELS largely.
