ACCON UK Limited (ACCON) were initially
commissioned to carry out a Noise Impact
Assessment for the proposed residential
development at 49-59 High Street in Southall.
The development comprises 131 residential units
across a building varying from three to eight storeys
in height. At ground floor level, commercial units
were proposed.
In order to establish any constraints on the
development from existing noise sources, a baseline
noise measurement survey was carried out by
ACCON to determine the noise levels during the
daytime and night-time. The results of the noise
measurement survey were used to calibrate a noise
model of the development site and surrounding
environs.
The predicted noise levels at the various building
façades were used to provide advice on the
minimum façade sound insulation required to
achieve the target internal noise levels within
habitable rooms. Our report supported a full
planning application for the proposed development.
The Local Planning Authority set five planning
conditions relating to noise on the planning consent.
Three of these planning conditions related to the
level of sound insulation between rooms of various
uses including residential to residential, residential
to commercial, and residential to plant rooms and
lifts.
ACCON carried out detailed sound insulation
assessments and liaised with the architects to
determine suitable alternative design solutions to
achieve the targets set by LBE.
The other planning conditions included a detailed
BS 4142 assessment of the proposed plant
installations on noise sensitive receptors and
detailed duct attenuation calculations to determine
the resultant internal noise levels due to the
operation of the proposed mechanical ventilation
systems.
Individual reports were prepared to be submitted in
support of discharging the relevant planning
conditions.
