| Research Abstract |
The Steerable Parametric Loudspeaker that we have proposed is able to generating multiple independent and super-directive audio beams, and controlling the angles of the beams. In this report, we describe about array processing of transducers for isolation of the beams, and an experiment about reflected beams from semicircular wall. This system allows to reproducing sound beams from any directions to the listening area, though the speaker is set up in one place.
