A modified algorithm for a loudspeaker line array multi-lobe control

The creation of personal sound zones is an effective solution for delivering personalized auditory experiences in shared spaces. Their applications span various domains, including in-car entertainment, home and office environments, and healthcare functions. This paper presents a novel approach for the creation of personal sound zones using a modified algorithm for multi-lobe control in loudspeaker line array. The proposed method integrates a pressure-matching beamforming algorithm with an innovative technique for reducing side lobes, enhancing the precision and isolation of sound zones. The system was evaluated through simulations and experimental tests conducted in a semi-anechoic environment and a large listening room. Results demonstrate the effectiveness of the method in creating two separate sound zones.
