The standardised impact sound insulation in the laboratory Ln is determined according to

~EN ISO 10140-3:2010 Acoustics - Measurement of sound insulation in buildings and of building elements - Part 3: Measurement of impact sound insulation~

A detailed description of the measuring procedures can be found in this standard. In simple terms, the determination principle can be summarized as follows :

The impact sound is generated by the standardised tapping machine (lNith steel-headed hammers) lNhich is set successively at various positions on the test floor. For each position, sound pressure measurements are carried out with the help of a continually rotating microphone in the measuring cell located beneath the floor. Measurements are done during at least one complete rotation and in three different planes of rotation. One thus obtains an integration over time and space of the sound pressure level spectrum, lNhich results in an average sound pressure level. The reverberalion time in the receiving room is measured, lNhich permits one to calculate the correction term to be integrated into the fonnula for calculating the standardised impact sound level :

lNith:

p::;;~~ip~+iOiOg (A I A,)i

Lpm = the average pressure level in the receiving room, in dB (reference 20 Micro Pal ; Au = reference surface 10 m2; A = the equivalent absorption-surface of the receiving room in ml.

2. Determination of the standardised impact sound level of the measurement support floor

The measurement support floor consists of a 14 cm thick solid reinforced concrete slab (dimensions: see figure in annex 1). The standardised impact sound insulation is determined according to 1.

3. Determination of the standardised impact sound insulation of the floating floor construction

FLOATING FLOOR: The ''floating'' covering floor is installed on top of the measurement support floor betVJeen the raised edges of the measurement support floor, allowing as such to take into account the side contact insulation. FLOOR COVERINGS: These are placed in at Jeast 5, evenly spread places on the measurement floor. A description of the floor covering and its mounting on the measurement floor can be found in point 3 on page 2. The standardised impact sound insulation of the floating floor construction is determined according to Doint 1. The result is reoresented on oaae 4.

4. Determination of the impact noise level reduction by the floating covering floor (AL)

The impact noise level reduction represents the difference of the standardised impact sound insulation of the measurement support floor alone minus the standardised impact sound insulation of the total floor (support floor + covering). It is the best way to acoustically characterise the product tested. The results can be found on page 3.

5. Determination of the sound pressure level of the standardised impact sound Ln,r of a fictions, normalised reference support floor covered with the testconstruction

The standard EN ISO 717-2:1996 gives the pressure level range of the standardised impact sound Ln,r,O of a reference support floor. The calculated sound pressure level Ln,r of the standardised impact noise of the reference Hoar covered with the covering subjected to the lest is calculated from this value and the reduction of the noise level according to :

Ln,r = Ln,r,D .. AL

6. Single value indicators.

The single-value indicator (given by the index "vi') is described in the standard :

"EN /50 717-2:1996 Acoustics-Rating of sound insulation in buildings and of building elements - Part 2: Impact sound insulation (ISO 717-1:1996) " The calculation of the single-value indicator cannot be summarised in a few lines. See standard for details.

Old national single-value indicators (NL, B, FR) are also given in the annex to this report. Calculation modules and more information about the single-value indicator (and about acoustical standardisation in general) can be found on the website of the Acoustics laboratory, Le.:

Hel mil dal de vloer tot een bapaalde celegatie bahoorl, wordt bepaald door de ligging van hel spectrum van hel door deze vlcer overgebrachte contaclgeluid Lo.v. de spectra, die de categorieen begrenzan. Wanneer het gemelen spectrum een of meer grensspectra snijdl, is hal de rigging van het ongunsligste deel van hat spectrum die de categone van de wand bepaaH. Nochtans, wanneer de Dverschrgdingen in de ongunslige zin (boven een grensspectrum) zoderng zijn del hun som in om hel even welke groep van 6 opeenvolgende lertsbanden I<:leiner is dan of gelijl<: aan 12 dB, dienl hiermee geen rel<:ening gehouden Ie worden.

DETERMINATION DE LA CATEGORIE l 'appartenance d'un plancher a une cah'igorie est determinee par la Situation du spectre des bruils de transmis par ce plancher par rapport aux speclres delimitant les categories. Dans Ie cas OU Ie spectre mesure chevauche un ou plusieurs spectres·limites, c'est la situation de la partiela plus defaVOfable dU spectre qui esl determinante pour Ie classement du plancheT. Touiefois, lorsque les depassemenis dans Ie sens defavorable(au-dessus d'un spectre·limlle) sontlels que leur addition dans n'importe quel groupe de 6 tierces successives esl inferieure a 12 dB, il n'en n'esl pas tenu compte pour Ie classement en categories.
