ABSTRACT:
To conclude, in a preferred embodiment in accordance with the invention, the sound system comprises two loudspeakers (LA, LB) which mask their spectral signatures at the ear (C1) of the listener by positioning the two loudspeakers (LA, LB) such that their maxima of the polar radiation patterns have directions which at least differ 30 degrees, and which generate coherent sound in the direction of the listener. These two aspects together cause different gradients of the sound of the two loudspeakers (LA, LB) at the same ear (C1) of the listener, while the information which reaches the ear (C1) from the spatially shifted different loudspeakers (LA, LB) is still coherent and not blurred by diffusion. The loudspeakers LA, LB should be spaced apart to obtain sufficient different gradients of their sound at the same ear.
