Three dimensional sound field
Three dimensional sound field
This lecture is an introduction to the physical and mathematical fundamentals of the sound field in three dimensions. The sound field is described as the linear superposition of plane waves impinging, in general, from all possible directions. The theory of Fourier transform and of spherical harmonic decomposition is briefly reviewed and applied to the representation of sound fields. The basics of 3D audio capturing and reproduction, the concept of spatial impulse response of a room and Auralization are briefly presented and analysed in relation to the theory introduced. Finally, the more mathematically challenging topic of integral representation of sound fields is discussed briefly.
