ISO 9613 needed
Help, please!
I need ISO 9613 "Attenuation of Sound During Propagation Outdoors" parts 1(1993) & 2(1996) norm.
I'm writing an essay and I need to study it thoroughly.
If anyone has at least part 1 (ISO 9613-1:1993) it would be much appreciated.
In return, I can help if anyone needs ISOs 1899-2 (1998), 7935, 8467 (1993), 9096, 10780 (1997), 10849 (1996), 12039 (2001), 14793 (2005).
