    • A robotic system for space-time characterization of parametric acoustic sound sources 

      Fantinelli de Carvalho, Augusto Cesar; Arnela, Marc; Brandao, Eric; Fernandez Grande, Efren (Proceedings of the 11th Convention of the European Acoustics Association Forum Acusticum 2025, 2025-06)
      Parametric acoustic loudspeakers use arrays of ultrasonic transducers to generate audible fields through the non linearities of the propagation medium. Despite being commercially well consolidated, some ...

    • Flat and cuverd parametric acoustic loudspeakers measured with exponential sine sweeps 

      Fantinelli de Carvalho, Augusto Cesar; Arnela, Marc (Proceedings of the 11th Convention of the European Acoustics Association Forum Acusticum 2025, 2025-06)
      Parametric Acoustic Loudspeakers (PALs) utilise ultrasounds to generate an audible field thanks to a non-linear effect in air. This phenomenon is difficult to simulate, so an alternative is to rely on ...
