APPENDIX 2
METHOD OF EVALUATION AND EXPRESSION OF THE RESULTS
IMPROVEMENT OF THE IMPACT SOUND INSULATION L
Determination of the improvement of impact sound insulation by the floor coverings on a heavy standardized concrete floor with a standardized tapping machine. The measurements must be run into a test laboratory.
Method of evaluation : NF EN ISO 10140-3 (2013)
Measurement by 1/3 of octave, from 100 to 5000 Hz: - Of the impact sound level Li into the reception room - Of the background noise level - Of the reverberation time of the reception room T
Calculation of the standardized impact sound level Ln in dB for any 1/3 of octave: Ln = Li + 10 log (A0/A)
Li : impact sound level measured into the reception room and eventually corrected by the background sound level
A0 : Reference area equal to 10 m² in laboratory A : Equivalent absorption area in the reception room
in m² A = (0,16 x V)/T with V the volume of the
reception room in m3 and T the reverberation time of this room in s
Calculation of the improvement of the impact sound insulation L in dB for any 1/3 of octave:
ΔL = Ln0-Ln
Ln0 : Standardized impact sound level of the standardized heavy concrete floor without any floor covering,
Ln : Standardized impact sound level of the standardized heavy concrete floor with the floor covering.
Expression of the results:
Calculation of the of the standardized impact sound level of the reference floor covered by the floor covering submitted to the test in 1/3 of octave from 100 to 3150 Hz: Ln,r = Ln,r,o – ΔL
- Ln,r,o : Impact sound level of the reference floor, - ΔL : Improvement of the impact sound level
Calculation of the ΔLw:
ΔLw = Ln,r,o – Ln,r,w = 78 dB – Ln,r,w.
For the calculation of the Ln,r,w, consideration of the Ln,r by 1/3 of octave from 100 to 3150 Hz with a 1/10th of dB precision.
Vertical movement of a reference curve by jump of 1 dB until the sum of the unfavourable distances is the biggest while remaining lower or equal to 32,0 dB.
Ln,r,w is the value given then by the curve of reference to 500 Hz.

CORRECTED IMPACT SOUND PRESSION LEVEL Ln,e
Determination of the impact sound level into a room by the floor coverings put into this room. The measurement must be realized in a laboratory and the tapping machine is standardized.
Method of evaluation : NF S 31-074 (2002)
Measurement by 1/3 octave, from 100 to 5000 Hz: - of the impact sound level Li in the reception room - of the background noise - of the reverberation time of the reception room T
Calculation of the standardized impact sound level Ln in dB for any 1/3 octave: Ln = Li + 10 log (A0/A)
Li : Impact sound level measured into the reception room and obviously corrected by the background noise
A0 : Reference area equal to 10 m² in laboratory

/10)-10 (LBR
/10) + 10((LBR+Ln,r,0 – LD)/10))
LH0 : Measured standardized impact sound level of the concrete floor on the top
LB0 : Measured standardized impact sound level of the concrete floor down LHR : Measured standardized impact sound level with the floor covering, on
the top LBR : Measured standardized impact sound level with the floor covering,
down LR : standardized impact sound level due to the relative movement of the
floor covering , on the top LDR : standardized impact sound level due to the relative movement of the
concrete floor, on the top and down LD : standardized impact sound level of the concrete floor, on the top and
down Ln,r,0 : standardized impact sound level of the reference concrete floor
Expression of results : Calculation of the overall weighted index Ln,e,w according to NF EN ISO 717-2 (1997)
On the values of Ln,e for any 1/3 octave between 100 and 3150 Hz with a 1/10 dB precision. Vertical moving of the reference curve by 1 db step until the sum of the unfavourable differences is the biggest while remaining lower than 32 dB.

APPENDIX 2
METHOD OF EVALUATION AND EXPRESSION OF THE RESULTS
AIRBORNE SOUND INSULATION R
Method of evaluation : NF EN ISO 10140-2 (2013)
The standard NF EN ISO 140-3 (1995) is the method of evaluation of the airborne sound insulation of the building elements like walls, floors, doors, windows, façade element, façades, …
The measurement must be run into a test laboratory without any flanking transmissions. The test facility is composed of two rooms : One fixed room where we put onto the concrete frame with the sample to be tested and a moving box, creating a couple “ emission room – reception room ». Those rooms and the concrete frame are separated (neoprene seals) and are in accordance to the standard NF EN ISO 140-1 (1997). The conception of rooms (box in the box) gets a strong soundproofing towards the outside and allows to measure very weak levels of background noise.
Measurement by 1/3 of octave, from 100 to 5000 Hz :
- Of the background noise level in the reception room LBdF
- Of the insulation: LE – LR
- Of the reverberation time of the reception room T
Calculation of the airborne sound insulation R in dB for any 1/3 of octave :
R = LE – LR + 10 log (S/A)
LE : Sound level in the emission room in dB LR : Sound level in the reception room, corrected with the background sound in dB S : surface of the sample to be tested in m² A : Equivalent absorption area in the reception room in m²
A = (0,16 x V)/T with V the volume of the reception room in m3 and T the reverberation time of this room in s.
The more R is high, the more insulating the element is.
Expression of the results: Calculation of the overall weighted index Rw(C;Ctr) according to the standard NF EN ISO 717-1 (1997)
Consideration of the values of R by third(third party) of octave between 100 and 3150 Hz with a precision in the 1/10th of dB.
Vertical movement of a reference curve by jump of 1 dB until the sum of the unfavourable distances is the biggest while remaining lower or equal to 32,0 dB.
Rw dB is the value given then by the curve of reference to 500 Hz. The terms of adaptation to a spectre (C and Ctr) are calculated by means of reference spectres to obtain:
RA,tr = RW + Ctr dB The terms of adaptation to a spectrum (C and Ctr) are calculated with reference spectrum to obtain:
The insulation towards noises of airport or industrial neighbourhood, activities: RA = Rw + C in dB
The insulation towards the noise of infrastructure of ground transport :
RA,tr = RW + Ctr in dB

PRINCIPLE:
The determination of the system mass / spring / mass resonance frequency fr allows to obtain the apparent dynamic stiffness per unit of area s't of the sample according to the equation:
t
t
'm
's
2
1 fr
with: m’t the total weight per unit of area used during the test
The measurement setup used by the laboratory is constituted by a Pulse analyser system which manages an excitation signal said "white noise", amplified by a power amplifier before being transmitted to an electro-dynamic shaker. An impedance head measures the injected force injected as well as the velocity of the system mass / spring / mass. These signals are then amplified by pre-amplifiers before being passed on to the Pulse analyser system to be treated and analysed.
