Acoustic Problem: Impact Sound
Impact Sound is structural airborne sound radiated to an enclosure by a wall or floor of a
building when it is structurally excited by common activities such as foot-fall, slamming doors,
movement of furniture, blows on the wall etc.
When generating an impact on a rigid structure, the
structure vibrates radiating part of the unabsorbed
energy and transferring it to the structure of the building, to connected building elements and finally to
the adjacent disturbed air particles. This generates
induced airborne noise with little attenuation. As impact noise is a phenomenon with a lot of energy in all
frequencies, it is difficult to attenuate.

Impact Sound insulation Solutions
Consequences of Impact Sound
Impact noise problems have increased in recent years,
mainly because lighter construction techniques have
replaced the heavier ones of the past. These more
flexible buildings are more sensitive to conveying and
resonating structural airborne noise. Impact noise in
the building, can cause a lot of problems:
On people’s health, altering the normal activity at
home and their rest. Impulsive noise produces stress
in, irritability, acceleration of the respiratory rhythm
and muscular tension.With impulsive noise the probability of waking up increases, diminishing the quality
of sleep. A well insulated space is crucial in order to
avoid health problems.
Of cohabitation between dwellings or with some place
of excessively noisy activity. Some of the main conflicts between neighbours in the same community are
due to the excess of structural airborne noise.
8
Impact Sound Solutions
To avoid these undesirable phenomena in noise generation, elastic materials are used under floating slabs,
floors or any type of floor finishing. The floating floor
acts as a protector, so when some impact occurs, it
vibrates but due to elastic support, only a very small
proportion of this vibration is transmitted to the structural floor. It radiates much less noise on the lower or
lateral enclosure than if the same impacts directly hit
the structure. The energy absorbed by the material is
transformed into low-level heat thanks to a high loss
factor (η) and damping (static deflection).
The most practical and economical alternativet to reduce impact sound noise is to intersperse elastic ma-
terials between the forge and the floating floor system
(wet or dry). A floating floor is the one insulated (decoupled) from the structural floor (forged), with elastic layers, leaving no rigid contact point between the
floors.
We have to take into account that in addition to vibrations transmitted to the receptor enclosure, the
impacts can also generate air noise levels in the emitting enclosure when the elements are lightweight and
low-cushioned. This is why a balanced solution which
reduces the noise level in the receiver enclosure without increasing it in the emitting enclosure is to be
achieved.

dBimpact Solutions
The solutions for impact noise are classified into two groups depending on the location of the
material in the floor system:
- Below floor-finishing solutions: Underlays (UL)
- Below Floating-Screed: Underscreed (US)
What is dBimpact Underlay (UL)?
dBimpact UL are materials based on low and high
density polymers of different elastic, compressions
and thermal properties to offer the best performance
for each type of floor covering.
The most elastic solutions have excellent acoustic properties both of impact sound and drum sound reduction
(also called reflected wlaking sound).
The hardest solutions are aimed at providing stability and
dynamic stiffness to more flexibl floor finishing, which
have less impact sound insulation problems. Therefore
dBimpact UL have better compression properties than
10
other equivalent solutions and offer excellent durability
and thermal properties.

What is dBimpact Underscreed (US)?
dBimpact US are elastic granulated materials coupled
with a flexible binder using the Slow Blended Cold
Calandered (SBC2 ®) technology with an anti-rupture
layer. Its manufacturing process gives it greater elastic
properties due to the encapsulated air between the
non-pressed but calandered elastic particles.
The elasticity of the binder together with the rubber
particle itself provides higher insulation performance
than similar materials under the concrete slab.
Its mechanical properties (low dynamic stiffness and
high compression resistance) allow to perform with great
efficiency in a wide range of loads of concrete or dry slab.
