3D Sound
sonic emotion technology uses wavefield synthesis and soundfield reproduction to eliminate the physical dimensions of a room and transform it into a virtual soundfield. With wavefield synthesis sonic waves are produced and dispersed throughout the listening room ensuring localization of virtual sound sources does not depend on or change with the listener's position. As in a natural environment real sounds are heard from all around regardless of the device positioning.
