AB  - When a loudspeaker of a mobile device is used in a public space, the side effects are the lack of personal privacy and annoying other people. There is, therefore, a need to reduce radiated power while preserving the sound pressure at the listener’s ears. Superdirective beamforming is one approach. A finite-element (FE) model of the two-source line array positioned on the mobile phone-sized baffle is defined and then used to investigate the effect of a finite-sized baffle on the directional pattern of the piston sources. Based on these results, a two-source personal audio system was implemented in real-time, and the results validated the predictions of the FE model. At frequencies where accurate transfer response measurements are achievable, the personal audio system performs as predicted by offline simulations.
