ASTM E966建筑物表面和表面构件气载声音隔离的现场测量标准指南
The best uses of this guide are to measure the OINR and the AOITL() or OITL() at specific angles of incidence. By measuring the AOITL() or OITL() at several loudspeaker sound incidence angles, by energy-averaging the receiving room sound levels before computing results, an approximation of the diffuse field results measu
