Spatial equalization of selected sound source by digital inverse filtering
The article presents digital inverse equalizers, enabling active sound control by means of directional characteristics equalization of selected sound source. Theoretical grounds of these systems are based on inverse filtration theory. Mathematical model of the equalizer, as well as experimental r...

| description | The article presents digital inverse equalizers, enabling active sound control by means of
directional characteristics equalization of selected sound source. Theoretical grounds of these
systems are based on inverse filtration theory. Mathematical model of the equalizer, as well as
experimental results confirming effectiveness of its operation have also been described in the
study, which presents directional characteristics of Visaton BG17 loudspeaker, and its selected
impulse responses prior to, and after equalization. |
