一组线阵列系统的性能在很大程度上取决于其扬声器的正确安装。例如,一个极性错误的单体扬声器可能会明显地影响整个系统的声压和指向性。然而,这种错误的鉴定非常耗时。因此,这就需要一种快速同时又可靠的方法来找出这样的线阵元素。介绍了一种怎样一步一步来检查一个完整的线阵列系统的方法,同时,还能找出引起极性问题的原因。除了理论背景,还描述了一个实际应用的成功案例。
The performance of a group of line array systems depends very much on the proper installation of their loudspeakers. For example, a single-polarity, single-cell speaker may significantly affect the overall system sound pressure and directivity. However, this wrong identification is very time-consuming. Therefore, there is a need for a fast and reliable method to find such line elements. Describes a step-by-step approach to inspecting a complete line array system while also identifying the cause of the polarity problem. In addition to the theoretical background, but also describes a practical application of success stories.
