APPENDIX 1
ANALYSIS PROCEDURE AND EXPRESSION OF THE RESULTS
SOUND REDUCTION INDEX R
 Method of evaluation: NF EN ISO 10140-2 (2013)
The standard NF EN ISO 10140-2 (2013) is the method of evaluation of the airborne sound
insulation of the building elements like walls, floors, doors, windows, facade element, facades, …
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 10140-5 (2013). 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 (2013)
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 spectrum (C and Ctr) are calculated by means of reference spectrum 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
RA = Rw + C en dB
•
The isolation towards the noise of infrastructure of ground transport: RA,tr = RW + Ctr en dB
