摘要
论证了两相同声源间中点的声强级最小,求出了两相同声源间的最佳距离为56.24 m.以韶关学院为例,给出了一种校园广播喇叭分布的优化方案.
This paper makes sure that the sound intensity in the middle is the lowest between two same loudspeakers, proves that the best distance between the two same loudspeakers is 56.24 meters. Then it gives an optimum project about placed broadcasting loudspeaker in shaoguan university campus.
