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
with best regards Stanley LIM
