DEVICE AND METHOD FOR ACOUSTICALLY IRRADIATING A SPATIAL REGION

The invention relates to a device for acoustically irradiating a spatial region (200), comprising at least one sound transducer array (100) with a plurality of flatly arranged individual sound transducers (11). The sound transducer array (100) is designed and can be operated so as to emit wavefronts (30) which correspond to a model with at least two virtual sound sources (1, 2) that lie behind the at least one sound transducer array (100) when viewed from the direction of the acoustically irradiated spatial region (200). The invention is characterized by a computing means (50) for actuating the individual sound transducers (11) in the at least one sound transducer array (100), wherein emission times for the same audio content are determined on the basis of at least one first virtual sound source (1) for sound transducers (11) in a horizontal arrangement (10) in the sound transducer array (100) and on the basis of at least one second virtual sound source (2) for sound transducers (11) in a vertical arrangement (20) in the sound transducer array (100). Emission times (t1) for the same audio content for the sound transducers (11) can be determined by the computing means (50) using the distance of the sound transducers to at least one first virtual sound source (1), regardless of a vertical position of the at least one virtual sound source (1) and the respective sound transducer (11), and the propagation time (t2) to each sound transducer (11) is added to the calculated values, said propagation time resulting from the distance of each sound transducer (11) to the at least one second virtual sound source (2), regardless of the respective horizontal position of the at least one first virtual sound source (1) and the respective sound transducer (11). The invention also relates to a method.
