Spherical loudspeaker array modeling and control using different basis function representations Academic Article uri icon

abstract

  • ABSTRACT A potential use of a spherical loudspeaker array for producing arbitrary radiation patterns has recently been studied. Different control strategies were developed and proposed for this goal. This work attempts to make a connection between two popular control strategies: the loudspeaker units input signals and the gains of spherical harmonics directivities. These control strategies make use of two sets of basis functions: caps' velocity and spherical harmonics, respectively, that fully span the radiation subspace. A new set of …
