AB  - This study investigates the relationship between the robustness of crosstalk cancellation and the symmetry of system configuration. Analytical results show that, with fixed sound source positions, increasing asymmetry due to deviations in the listeners head position or orientation leads to reduced system robustness, whereas optimal performance is consistently achieved in symmetric layouts. For asymmetric configurations, we propose a method to optimize the axial angles of the sound sources. This method leverages source directivity patterns to adjust level differences along the acoustic propagation paths, thereby improving system robustness. Experiments confirm the effectiveness of the proposed method in asymmetric crosstalk cancellation systems, demonstrating enhanced robustness and yielding higher binaural channel separation under slight listener head movements.
