Bibliography

This standard is included in DIN Handbook 35, 35-1 and 189. Establishes calculation models designed to estimate impact sound insulation between rooms in buildings. Primarily on the bases of measured data, characterizing direct or indirect flanking transmission by the participating building elements and theoretically derived methods of sound propagation in structural elements.
