Assessment of noise control measures for a model advanced ducted propulsor

Regulation of occupational exposure to noise in Britain for 50 years has reduced risk. However, statistics from around the globe (and in Britain alone) suggest that the range in harm is between around zero and more than 1 in 4 workers exposed to high noise. The uncertainty in statistics and the potential high incidence and prevalence of harm justifies investigation. In Britain, we will investigate the current risk of occupational hearing loss and the effectiveness of current noise control measures. We propose to gather data during inspections of industries that are known to have high levels of workplace noise. Finding high incidence of hearing damage will indicate a failure of immediate management of risk and likely result in enforcement action. We propose to review employers' control of noise propagation in the workplace through use and maintenance of noise controls supplied with machines and supplemented with acoustic barriers and noise havens. We propose to review suppliers design and build of noise control into their products and their reported noise emissions for noisiest typical use. We are looking to benefit from the experience of our global counterparts before finalising our plans.

And Storage

For the conveyance and storage of natural gas, compressor stations are required where the installed power output varies mostly between 1 MW and 20 MW. The noise control measures involved to meet the environmental noise emission regulations in Europe will be presented. The most economical noise control techniques are described particularly for the intake and exhaust systems of gas turbines, the housing of such engines, and peripheral sound sources like gas coolers, oil coolers, and aboveground piping.

Cement Manufacturing

The main environmental issues associated with cement production are the consumption of raw materials, energy use and emissions in the air. Noise emissions occur throughout the whole cement manufacturing process - from preparing and processing raw materials, from the clinker burning and cement production process, from material storage as well as from the dispatch and shipping of the final products. The heavy machinery and large fans used in the cement manufacturing process can give rise to noise emissions. Cement Plants are required to comply with standards for reduction in line with national legislation, and to conduct measurements and perform noise surveys. Having this in mind, A TITAN Group Usje Cement Plant in Skopje, following their strong commitment to high environmental performance and Corporate Social Responsibility and Sustainable Development Policy in 2013-2014 have engaged an AMBICON Lab (Faculty of Natural and Technical Sciences) from Stip, to conduct a Noise Control Study in order to identify noise sources within cement plant and marl quarry, determine their impacts on nearby residents and develop noise control/protection strategies. During the past three years, the Usje Cement plant has implemented most of the noise control measures proposed in this Study. Also, a follow-up study during 2016-2017 was conducted in order to assess the effectiveness of measures taken. This paper presents the outcomes of noise reduction measures taken.
