1. Determination or the standardised impact sound
The standardised impact sound insulation in the laboratory Ln is determined according to
HEN ISO 140· 6:1998 Acoustics - Measurement of sound insulation in buildings and of building elements - Part 6:
The standard EN ISO 717-2:1996 gives the pressure level range of the standardised impact sound In,r,O
of a re ference support floor. The calculated sound pressure level Ln ,r of the standardised impact noise of
the re ference floor covered with the covering subjected to the test is ca lculated from this value and the
reduction of the noise level according to:
Labora/ory measurements of impa ct sound insulation of floors (ISO 140·6:1998)"
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 slandardised tapping machine (with steel-headed hammers) which
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, which
results in an average sound pressure level. The reverberation time in the receiving room is measured ,
wh ich permits one to calculate the correction term to be integrated into the formula for calculating the
standardised impact sound level :
Ln,r
6, Single value indicators.
The single-value indicator (given by the index "w") is described in the standard:
"EN ISO 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, i.e. :
Ii:; = Lpm + 10 log (AI Ao)
with:
= Ln,r,o -l\L
Lpm = the average pressure level in the receiving room, in dB (reference 20 Micro Pa );
An = reference suriace 10 m'l ;
A = the equivalent absorption-surface of the receiving room in m 2 •
http://www.bbri.be/a ntenne norm
2. Determination or 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
figu re in annex 1). The standardised impact sou nd 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 lOP of the measurement support floor
between the raised edges of the measurement support rloor, allowing as such to take into account the
side contact insulation .
FLOOR COVERINGS: These are placed in at least 5, even ly spread places on the measurement rloor. A
description of the floor covering and its mounting on the measurement floor can be found in point 3 on
page 2.
The sta ndardised impact sound insulation of the floating floor construction is determined according to
point 1. The result is represented on page 4.

The impact noise level reduction represents the difference of the s tandardised impact be
the measurement support floor alone minus the standardised impact sound insulatior
(support floor + cove ri ng). It is the best way to acoustically characterise the product
be found on page 3.
