Noise Control Action Plan Implementation at BorsodChem 2/2

Few details of the noise control action planning at BorsodChem Ltd. outlined in the previous paper will be shown in this presentation.The first task was the installation of two monitoring stations for the observation of the noise. The monitoring stations are placed in the plant area in the direction the sound waves propagating towards the residential area. We are demonstrating some observation results of the project.The exhaust hood of a boiler exchange has been chosen for noise mitigation from the dominant noise sources. We are expounding the method of the noise mitigation and the noise measurement results for before and after conditions.For each sources and technologies, studies have been prepared before the start of implementation works regarding the detection of possible causes of the noise emission. Such studies have been made in the case of numerous cooling towers and a 2 m diameter fresh air supplying pipe. The tenders for the noise mitigation implementation works have been made based on these.The noise mitigation often have to be carried out in high noise level conditions. The control measurements was carried out by noise intensity measurements.
