AB  - In this paper, first we introduce the principle of synchronous averaging in frequency domain that is applicable to asynchronous systems where the transmitting side and receiving side are not synchronized. Then we discuss the possibility of applying synchronous averaging for measuring the distance of real or virtual sound sources. If the position of real or virtual sound sources in asynchronous systems can be identified, then there will be no need to consider the wiring of transmitting side and receiving side. This works well in applications of measurement at two or more points over a large space. Here, we identify the virtual sound source in asynchronous systems by using an adjacent 4 points method.
