Balancing climate change action with noise management<\/p>\n
Last week the Irish Government published its long anticipated Climate Action Bill and Low Development Bill to guide Ireland on its journey to This Bill, while arguably overdue, is refocusing attention on the renewable energy sector. Through our work, the team at Sonitus Systems support Green Prophet, a climate action website founded by biologist, journalist and tech entrepreneur Karin Kloosterman, recently published an The above article breaks down constituent noise pollution and how wind turbines contribute to this problem. It defines noise pollution as “any Interestingly, the author explains that wind turbine parks can also create infrasound, or low-frequency sound, which is noise below the lower How loud is loud? The article helpfully puts the noise levels in context by explaining that the average open office environment is We work with a network of experts to deliver reliable monitoring on projects all over the world; making sure people making decision get the To discuss automated monitoring, real-time reporting and other noise reduction strategies, contact the expert team at Sonitus Systems.<\/p>\n Balancing climate change action with noise management Last week the Irish Government published its long anticipated Climate Action Bill and Low Development Bill to guide Ireland on its journey to a “climate resilient, biodiversity rich, environmentally sustainable and climate neutral economy”.

\nWhile the Bill has already attracted criticism for not going far enough, the targets set out are objectively ambitious and each sector of the economy
\nhas responsibility for helping to achieve these ambitions through a system of carbon budgets, which will be assessed and evaluated

\nthe renewables sector as it rolls out green and sustainable power to positively impact climate change. However, this comes at a cost to the local
\ncommunity, so it is imperative that both the sector and the local community work together to achieve real change.<\/p>\n
\narticle titled ‘Do Wind Turbines Create Noise Pollution?’<\/a>, which delves deeper into this growing global issue.The article cites wind as the
\nmost cost-effective renewable power source available, claiming that “its operation creates no greenhouse gases, nor any pollution”. However,
\nthe author does acknowledge that turbines are the source of one very real and very harmful environmental pollutant, that is, noise pollution. As
\nregularly documented here, exposure to noise pollution can cause a litany of physiological and psychological problems for people.<\/p>\n
\nsound or noise that is louder than the usual background noise you hear”. Working wind turbines emit two different kinds of audible noise,
\nmechanical and aerodynamic. Mechanical noise is created by the friction between two components of the machinery, and vibrations induced by the
\nrotating components, including noise emanating from the generator, fans, and hydraulic systems. Whereas aerodynamic noise, which is the dominant
\nsource of noise from a turbine, is described as being “more complex”. It arises from the motion of the air around the blades, changing in relation
\nto the speed of the blades.<\/p>\n
\nlimit of audibility. According to the article, “studies conducted in the matter found that the infrasound produced is below the natural background
\ninfrasound, meaning it has no harmful consequences”.<\/p>\n
\napproximately 60dB(A), a loud concert can be up to 100dB(A) and a jet engine can be over 130dB(A). Wind turbines emit approximately 100dB(A)
\nof noise at source and this reduces significantly as the distance increases, for example, 250 meters away from the turbine, the noise level is
\napproximately 50dB(A) which decreases depending upon the strength of the wind. There are a number of other variables that contribute to this range,
\nincluding land topology, and these factors must feed into planning decisions going forward.<\/p>\n
