如果使用扬声器再现，则双耳音频需要使用串扰消除。作为这项工作的一部分，一个三个听众的串扰消除系统已被设计和建造。不同的扬声器分布的仿真和一个大的系统跨度，以增加低频串扰消除性能，而在给定的听众前面的一个密集的扬声器分布增加中高频串扰消除。系统的性能下的听众和扬声器的扰动进行了研究，并在高频扬声器远离任何给定的听众被证明是受扰动比那些更接近的听众。针对这个问题，开发了一种新的使用扬声器相关正则化来加权扬声器源强度的实现，并优化了该系统。因此，在高频下，仅使用靠近收听者的扬声器。当系统受到扰动时，这被示出为比传统串扰消除滤波器设计创建更鲁棒的解决方案
Binaural audio requires the use of crosstalk cancellation if reproduced using loudspeakers. A three-listener crosstalk cancellation system has been designed and built as part of this work. Simulations for different loudspeaker distributions are presented and a large system span is shown to increase low-frequency crosstalk cancellation performance whilst a denser loudspeaker distribution in front of a given listener increases mid to high-frequency crosstalk cancellation. The system’s performance under perturbation of the listeners and loudspeakers is investigated and at high frequencies loudspeakers further away from any given listener are shown to be affected more by perturbations than those nearer the listener. To this issue, a novel implementation of weighting loudspeaker source strengths using loudspeaker dependent regularization is developed and optimised for use in this system. Hence, at high frequencies just loudspeakers close to the listener are used. This is shown to create a more robust solution than traditional crosstalk cancellation filter design when the system has undergone perturbations
