摘要
早期侧向反射声对观众厅的音质有着重要作用。近年来也提出了若干可测描述符,但是测试方法至今仍未标准化.以致所得结果不能相互比较其问题在于没有找到正确捕获早期侧向反射声的方法本文介绍了一种使用方向性装置和存储示波器来捕获及识别它的测试方法。
The early lateral reflected sound energy is important to the acoustcs of the auditorium. Some measurable descriptors have been presented in the past few years. But so far the measuring methods have not been stand- ardized, and so the obtained results have not been compared. The problem is t- hat the correct method is not found to catch the early lateral reflections of s- ound. This paper in oduces a method using directional device and storage osc- illoscope to distinguich it. and presents a way, of obtaining the early lateral en- ergy fraction.
