Noise Control Action Plan Implementation at BorsodChem 1/2

This presentation is the first in a two-part series, reporting on the noise control action plan of Hungary's largest chemical factory.The nearly 2,5 km2 densely built up factory area is wedged into residential areas. More than 20 plants are working constantly on the area with thousands of individual noise sources.The exceedance of the noise limit is significant, however, greatly varies due to the meteorological conditions.Our task was the exploration of the dominant noise sources, building up a noise model and creating noise control action plan using complex testing methods.The aim of the presentation is to demonstrate the volume of the task, describe the challenges that we face when measuring such a complex system of noise sources.Hundreds of hours of noise measurements were taken on more than 500 measuring points in the area and surroundings of the facility. Noise monitoring stations were installed at different points of the facility for weather-impact analysis.The measurement of the open air technology or the inclusion of reference points above 30 meters posed a challenge during the model building process. We intend to vividly illustrate the above-described process in the framework of the presentation.
