The impact sound reduction is determined on the basis of the measured values as follows: L = L n,0 - L n (db) L n,0 Impact sound pressure level without a floor covering (db) Page 2 of 5 No. 658 Testing laboratory, inspection and certification body recognised by the DIBt (Deutsches Institut für Bautechnik) Accredited for the methods indicated in the annex to the DAkkS certificate Charlottenburger Allee 4 HRB 857 Aachen VAT No. DE Managing Director

5 TS L n Impact sound pressure level with a floor covering (db) For the evaluation of the weighted reduction in impact sound pressure level Lw, the relevant reference curve is shifted in increments of db towards the measured curve until the sum of unfavourable deviations is as large as possible, but not more than 32 db. The linear impact sound level Llin is determined according to the following equation: Lin = L n,r,0,w + C l,r,0 (L n,r,w + C l,r ) = L w + C l, L n,r,w is the calculated weighted normalized impact sound pressure level of the reference floor with the floor covering under test L n,r,0,w 78 db, calculated from L n,r,0 according to Section 4.3. of DIN EN ISO 77-2: 203 C l,r Spectrum adaptation term for the reference floor with the floor covering to be tested C l,r,0 - db, spectrum adaptation term for the reference floor with L n,r,0 determined according to Annex A, Section A.2. of DIN EN ISO 77-2:203 8 Note The results are based on measurements performed under laboratory conditions with artificial excitation (standard procedure). The test results are applicable in due consideration of the national provisions and the local circumstances and/or constructions.
