The mining and processing of
minerals is an important part of the economic development of the
country. Minerals can only be extracted where they exist and often
these locations are in rural areas with low background noise levels.
This can give rise to concerns about noise from proposed and existing
mineral sites. Hepworth Acoustics has considerable experience of
dealing with the noise issues at the planning stage of deep and surface
mines and open cast quarries.
The experience includes predicting future noise
levels, designing mitigation measures and representing clients through
the planning process and at
if required. In addition, the company can advise and carry out
compliance monitoring of working sites, which is often not straight
forward, because noise limits may be set very close to existing
background noise levels.
predictions for future minerals sites are carried out using the basic
calculation methodology from British Standard 5228: Noise and vibration
control on construction and open sites (BS 5228). The predictions are
carried out using a software package, and allow the effect of bunds,
barriers and soft ground attenuation to be assessed. The results of the
predictions are assessed using the procedures contained in Minerals
Policy Statement 2 (2005): controlling and Mitigating the Environmental
Effects of Minerals Extraction in England, Annex 2: Noise (MPS 2).
approach of Hepworth Acoustics is to work with the minerals operator to
develop a site working methodology that allows the site to proceed
whilst maintaining acceptable noise levels at nearby noise sensitive
We understand the working methods for mineral sites, the
options for noise control and the best ways to accurately predict the
noise levels generated. This builds on previous research carried out by
the company on source noise levels and prediction accuracy. This allows
clients to fully answer concerns regarding potential noise impact and
to be able to discharge the relevant planning conditions.
