Acoustic performance tests on CLT
Field measurements at the MT-Hotel
Location: MT-Hotel (Incoming Center Murtal) Hauptstraße 242 AT - 8740 Zeltweg Performed by: Schallschutz im Holzbau SSIH Dipl. Ing. (FH) Hans-Peter Buschbacher Scheuchenstulstraße 11 D-83024 Rosenheim E-Mail: [email protected] Customer: Stora Enso WP Bad St. Leonhard GmbH Wisperndorf 4 9462 Bad St. Leonhard Austria Date of testing: 24.05.2012 The tests were performed according to following international standards: airbourne sound: DIN EN ISO 140-4: 1998-12 Field measurements of airborne sound insulation between
rooms. Rating according to DIN EN ISO 717-1 : 2006-11 impaced sound: DIN EN ISO 140-7 : 1998-12
Field measurements of impact sound insulation of floors Rating according to DIN EN ISO 717-2 : 2006-11
Note: The results of field measurements are usually lower than the laboratory measured values. The difference between the results is due to flanking transmission on site.
