If CISPR24/EN55024 expects the SPL from loudspeakers to be measured, It had better specify EXACTLY how it is to be done. This is a very specialised area of technology, and errors could exceed 10 dB in unskilled hands. I don't have EN55024, but I will take this matter up in a place where it will receive attention. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Eat mink and be dreary! ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
