Dear all,
I am looking for the following articles and standard:
1. Paulus and E. Zwicker, ?Programme zur automatischen bestimmung 
der lautheit austerzpegeln oder frequenzgruppenpegeln Computer programs 
for calculating loudness from third octave band levels or from critical 
band levels,? Acustica 27, 253?266 1972. 
2. Zwicker, H. Fastl, and C. Dallmayr, ?BASIC-Program for calculating 
the loudness of sounds from their 1/3-oct band spectra according to ISO 
532 B,? Acustica 55, 63?67 1984. 
3. Zwicker and H. Fastl, ?A portable loudness-meter based on ISO 532B,? 
Proceedings 11th International Congress on Acoustics, 1983, pp. 135?137. 
4. ISO R 532
I will appreciate very much if you have it, to send a copy to me.
For your kind assistance
Thank you
with best regards
Stanley LIM
