研究了由于偏离中心听音而引起的立体声错觉退化的校正。这里的主要思想是扬声器阵列的指向性图案应该具有良好限定的形状，使得在大的收听区域中实现良好的立体声声音再现。最佳的数字滤波器的设计和应用到线性扬声器阵列的各个驱动器，以获得一个特定形状的方向性模式。这种形状是适应人类听觉系统的时间/强度的交易机制，通过心理声学实验在一个广泛的收听区域。该应用也被称为“位置无关（PI）立体声”。
The correction of the degradation of the stereophonic illusion due to off-centre listening is investigated. The main idea here is that the directivity pattern of a loudspeaker array should have a well defined shape such that a good stereo sound reproduction is achieved in a large listening area. Optimal digital filters are designed and applied to individual drivers of linear loudspeaker arrays in order to obtain a directivity pattern of a specific shape. This shape is adapted to the time/intensity trading mechanism of the human auditory system via psychoacoustic experiments within a wide listening area. This application is also referred to as "position independent (PI) stereo".
