5 page 3 of 15 STANDARD METHOD The normalised impact sound pressure level Ln and the reduction of sound pressure level (improvement of impact sound insulation) ΔL were measured according to the standard NBN EN ISO :2010. A detailed description of the test set up has been given in the figures of annex 1 of this report. The tests were measured as follows: - The test sample is mounted onto a heavyweight standard floor, in accordance with the descriptions in the standard NBN EN ISO and The standardized (see NBN EN ISO :2010 Annex E) tapping machine is positioned in 3 or 4 positions on the test floor (depending on the sample). The impact sound pressure levels are measured in the receiving room below the test floor using a moving microphone. A one-third octave band analyser measured the averaged sound levels in the third octave bands from 100 to 5000 Hz. If required, the levels are corrected to account for the background noise. The individual measurements are then averaged energetically for each one-third octave band and converted with the reverberation time measurements to the normalized impact sound pressure level Ln for a receiving room having 10m² of equivalent sound absorption area. - The normalized impact sound pressure level of the heavyweight standard floor Ln,0 is measured using the identical procedure. - The normalized impact sound pressure level is calculated according to the following equation: L n = L i + 10 log (A/A 0 ) [db] met L n = The normalized impact sound pressure level, expressed in db (ref 20µPa) L i = the energy average sound pressure level in a one-third octave band in the receiving room when the floor under test is excited by the standardized tapping machine A 0 = the reference equivalent absorption area (= 10m²) A = the measured equivalent absorption area - The temperature, relative humidity and static pressure is also measured in the test rooms. - The improvement ΔL of the impact sound insulation is calculated from the difference between the weighted impact sound levels of the bare floor without and with the floor covering: L = L n,0 - L n [db] met L = The improvement of the impact sound insulation L n,0 = normalized impact sound pressure level of the bare floor L n = normalized impact sound pressure level of the bare floor with floor covering

6 page 4 of 15 STANDARD METHOD Single rating numbers Evaluation according to EN ISO defines single-number quantities, L n,w (C i ) for the impact sound insulation of floors and ΔL w (C I,Δ ) for the impact sound reduction of floor coverings and floating floors from the results of measurements carried out in accordance with NBN EN ISO The values obtained in accordance with ISO are compared with reference values at the frequencies of measurement within the range 100Hz to 3150 Hz for measurements in one-third octave bands. The calculation of the single-value indicator can not be summarised in a few lines. See standard NBN EN ISO for details. L n,w = weighted normalized impact sound pressure level L n,w +C i = weighted normalized impact sound pressure level corrected with the adaptation term Ci C i = L n,sum L n,w With L n,sum the summation on an energetic basis for the one-third octave bands in the frequency range 100Hz to 2,5kHz L n,sum = Calculations of the spectrum adaptation term may additionally be carried out for an enlarged frequency range. The single-number quantities of impact sound insulation properties of floors, presented as L n,w (C i ) The single-number quantities of the weighted reduction in impact sound pressure level for floorcoverings, is presented as L w (C i, ) and L lin The normalized impact sound pressure level of the bare floor The normalized impact sound pressure level of the bare floor with floor covering L n,0 = L i + 10 log (A/10) and L n,0,w (C I,0 ) L n = L i + 10 log (A/10) and L n,w (C I ) L = L n,0 - L n Reduction of impact sound pressure level To compare the measurement results obtained in different test laboratories, the normalized impact sound level Ln, is referred to the reference floor defined in ISO in the following way. The quantity is designated by the index "r" ("reference floor"): L n,r L n,r = L n,r,0 - L and L n,r,w (C I,r) with L n,r,0 is the defined normalized impact sound pressure level of the reference floor (see ISO point 5.2) L w = L n,r,0,w - L n,r,w = 78 - L n,r,w with C I, = C I,r,0 - C I,r = C I,r L lin = L w + C I,

7 page 5 of 15 SPECIAL MEASUREMENT CONDITIONS / ACCURACY The accuracy of the impact sound insulation as calculated can be expressed in terms of repeatability (tests within one laboratory) and reproducibility (between various laboratories) Repeatability [r] When: - two tests are performed on identical test material - within a short period of time - by the same person or team - using the same instrumentation - under unchanged environmental conditions - the probability will be 95% that the difference between the two test results will be less than or equal to r Reproducibility [R] When: - two tests are performed on identical test material - in different laboratories - by different person(s) - under different environmental conditions - the probability will be 95% that the difference between the two test results will be less than or equal to R In NBN EN there is a statement on the reproducibility R to be expected, based on the results of various inter-laboratory tests. The reproducibility of the single figure rating Lw, ΔLw is about 3 db.
