Delivering Bespoke Acoustic Solutions
December 30th 2010
Whether the project is an office block where outside noise needs
to be suppressed, or schools and hospitals that require sound
insulation between specific rooms, when it comes to acoustics there
are performance needs that must be satisfied, sound insulation is a
major factor across all industries. Whenever we are faced with a
new project we need to consider exactly what acoustic issues need
to be addressed.
Different sectors have different requirements for required
acoustic reduction levels, from the education sector (BB93) to the
health sector (HTM2045) to Commercial and office environments
(BS8233:1999). All these different regulations mean that acoustic
solutions need to be tailored to the specific requirement, a
standard 'across the board' level does not apply and a custom panel
system needs to be implemented if practical acoustic solutions are
to be found.
It is important to consider that as well as many different types
of noise, there are also many different methods of noise
transmission. Airborne noise and impact noise are the most common
to consider, especially driven rain on wall elements but there is
also internal noise reverberation (How sound waves are reflected
and absorbed) and flanking (the transmission of sound around
the perimeter or through partition holes) to consider.
The types of noise that needs to be controlled is dependent on a
number of factors. All buildings need some sort of acoustic control
in order to meet standard regulatory requirements (e.g. Building
regulations Approved Document E) or even specific client
requirements and panels have an excellent level of acoustic
reduction due to the density of the mineral wool core (when
compared with PIR Foam panels). It is a basic principle that
as the density is increased, the acoustic reduction is also
increased. This is only the beginning of the potential solutions
and Eurobonds technical department are ready to provide specific
solutions for the most demanding environments.
Correctly specifying against these varying regulations and
varying sectors can prove to be a minefield, Eurobond are
addressing this by offering a series of standard design details
which show how the desired acoustic reduction can be achieved as
effectively as possible.
Eurobond's improved acoustic reduction solution is provided by
using through-wall constructions with a combination of layers which
include Eurobond panels, Rockwool Flexi acoustic slabs and
plasterboard. Eurobond can now provide a series of standard
configurations to improve acoustic performance and with various
combinations/arrangements it is possible to offer acoustic
reductions to satisfy any environment, building regulation, or
specified performance level with potential reductions of up to 140
dB. This pre-defined selection of configurations will allow
specification to be easier than ever before with the additional
benefit of Eurobonds in house expertise to ensure that any solution
provided will be in line with the most current regulations for
application.
