Abstract:
Around a chemical plant in Hungary exceedance 2-13 dB of noise immission can
be
measured in populated area. The authority ordered plan for noise abatement.
The
plant is located between 3 settlements on an area of 700 X 4000 m2. It has
more
then 1000 noise sources in 20 workshops – they work continuously,
simultaneously,
hardly selectable manner. It is practically unreal to swich noise sources in
and
out on purpose, to operate them selectively. Source identification is
possible
only by synchronous measurement near and far from individual sources,
calculation
of transmission and use of monitoring technique. These measurements gave
possibility to analyze the effects of meteorology.
We constructed a virtual noise model of the plant with noise mapping
software with
acoustically substantial data. During work we determined the proper noise
load of
workshops, source groups and individual sources in critical immission
points. We
also decided what depth it is necessery to deal with technical details of
noise
reduction techniques. We suggested conceptual reduction solutions. The main
goals
in this work were timing and cost budget.
This paper summarizes our observations during work.
