WIENERBERGER TESTVERSLAGEN AKOESTIEK
Kij knoopreducties van Appartementen toepassing 4
Hierbij worden de knoopreductiecoëf gegeven over de aanzet van een
dubbele wand + verdieping op een funderingssokkel met doorlopende
vloerplaat.
Voor de doorlopende funderings-vloerplaat werd geen specifieke test
gedaan, maar werd de test genomen van een doorlopende betonplaat uit
de appertementensimulaties. (test 09)
Aangenomen kan worden dat deze test zeker de meest nadelige
benadering van de situatie zal zijn wegens het bijkomende effect van de
dissipatie dat zal optreden bij vloerplaten op volle grond.
Voor de bovenste verdiepingen werden testen 05 en 06 (onder belasting,
met enkele strip) gedaan voor knoopreducties over wanden onderbroken
met de akoestische strip WB160 (sonic strip) van Wienerberger.
Voor de doorlopende vloerplaten aan de tussenverdiepen werd test 07 en
09 uitgewerkt
Om tot een Dntw bepaling te komen moeten deze gerecombineerd
worden met de Rw waardes van de opbouwende wanden.
Bijkomend werd een celtest gedaan van de volledige opstelling met
gelijmde snelbouwstenen in combinatie met akoestische matten
(150kg/m² + dubbele (boven en onder) sonic strips)

Mounting description : A cross junction composed of a continuous concrete floor and a double brick wall. A resilient joint
is inserted between the brick walls and the floor. The resilient joint is a resinbonded rubber with a
thickness of 0.01 m and a width of 0.14 m. The brick walls are not plastered. The cavity between
the brick walls is filled with mineral wool and measures ± 0.03 m.

Annex 1 : MEASUREMENT METHODS
Measurement method to determine the vibration reduction index, Kij
General
The vibration reduction index Kij expresses, in a way, the attenuation of the power flow through a junction. The draft prEN ISO 10848-1 to 4 gives a
measurement method to obtain this index in laboratory.
The principle of measurement for Kij is based on tis formula :
The required quantities are the length of the junction lij [m], the direction averaged level difference [dB] and the equivalent absorption lengths ai [m]
and aj [m]. All these quantities are obtained by vibration measurements with structure-borne excitation. is obtained from the mean value of the
velocity level differences Dv,ij and Dv,ij. Dv,ij (Dv,ji) is the difference between the surface average velocity level of the wall i (j) and the wall j (i)
when the wall i (j) is excited at several points.
ai and ai are determined according to the measurement of the structural reverberation times Ts,i and Ts,j :
Sj is the surface area of the wall j [m²];
Tsj is the structural reverberation time of the wall i [s];
c0 is the speed of sound in air [m/s];
f is the current frequency [Hz];
fref is the reference frequency [fref = 1000 Hz].
Generation of vibration on the source element
Multiple hammer hits with approximately the same strength are given over an area of 1 m2 –2 m2 during a time period of 30 s.
Performance of the measurement
On each element (source and receiving plate) three (3) excitation positions and a twelve (12) transducer positions are be used. For each excitation
position four (4) different pairs of transducer positions is used on each element. All positions are randomly distributed over the surface of the element, bu
not symmetrical.
The transducer positions and excitation points shall be arranged using the following minimum distances:
· 0,5 m between excitation points and the test element boundaries;
· 1,0 m between excitation points and the junction under test;
· 1,0 m between excitation points and the associated transducer positions;
· 0,25 m between transducer positions and the test element boundaries;
· 0,5 m between the individual transducer positions.
The maximum distance between transducer positions and the junction under test is 3,5 m.
In each frequency band the measured velocity level shall be at least 10 dB higher than the background noise level. in any frequency band. If this is not
fulfilled, corrections shall be applied as shown in EN ISO 140-3. The correction value must not exceed 1,3 dB.
Measurement method to determine the structural reverberation time, Ts
Ts is the structural reverberation time of a wall [s]. It represents the time that would be required for the velocity or acceleration level in a structure
to decrease by 60 dB after the structure-borne sound source has stopped.
The hammer excitation method is used. Different masses and materials are used for an impact hammer because different material
leads to different excitations in frequency bands.
Measurement and excitation points
At least three excitation points shall be used on the test element. At least three transducer positions shall be used for each excitation point.
The transducer positions and the excitation points shall be arranged using the following minimum distances:
· 1 m between the excitation point and the associated transducer positions;
The measurement points shall be randomly distributed over the test element.

2. Diffuse vibration fields : if the measured velocity level decreases by more than 6 dB over the allowed measurement area for any elemen
of the tested junction, when the accelerometer is moved away from a stationary vibration source, then the measured Kij may not be

Mounting description : A T-junction with flexible interlayers: the vertical walls are made of Silentbrick (thickness : 0.14m)
and interrupted by 4 perpendicular hollowcore slabs. Wall n°1 is plastered on the CEL1 side. The
resilient joint is placed between the slabs and wall 1. The resilient joint is a resinbonded rubber
from CDM with a thickness of 0.01 m and a width of 0.14 m. A system of steel beams and
pneumatic jacks loads the vertical walls with a pressure of 150 bars in the pneumatic jacks after a
period of load (190 bars) of 1 week.

Mounting description : A T-junction with two flexible interlayers: the vertical walls are made of Silentbrick (thickness :
0.14m) and they are interrupted by 4 perpendicular hollowcore slabs. Wall n°1 is plastered on the
CEL1 side. A resilient joint is placed between the slabs and wall 1. The other is placed between the
slabs and wall 3. The resilient joint is a resinbonded rubber from CDM with a thickness of 0.01 m
and a width of 0.14 m. A system of steel beams and pneumatic jacks loads the vertical walls to
simulate different storeys.
