Industrial Acoustics For Worker Health & Safety
The industrial sector is one of the most common areas where noise is a problem. Factory and manufacturing environments are generally large, comprised of hard surfaces and high ceilings; and contain production equipment that emit a large amount of harsh noise. These factors combine to make industrial acoustics often uncomfortable and harmful. With loud noises from machinery amplified by highly reflective surfaces, industrial noise can be a serious issue that not only affects the wellbeing of staff, but one that is likely to breach health & safety regulations.

Industrial Deafness: The New Whiplash” description=”Insurance companies are becoming increasingly aware of the sharp rise in industrial deafness claims over the last decade. In the two years to 2012, the UK’s top three insurers, RSA, Zurich and Aviva, each reported an overall average increase of 33% in industrial deafness claims, with the phenomenon being dubbed the new ‘whiplash‘. (‘This Is Money, 30 August 2014)”]
- As well as the risk of permanent hearing damage, excessive decibel levels in the workplace can cause a range of health and wellbeing issues for employees. In cases where hearing protection must be worn, feelings of isolation and discomfort are often reported. Excessive noise on a constant basis also causes fatigue and stress which in turn increases staff turnover and sick-leave – both of which have a negative effect on profitability.
- Clear communication between staff and the ability to hear important announcements are implicit in providing a safe working environment. Many industrial work settings present a higher number of safety risks due to the machinery and tools required to undertake work in these environments. Therefore it’s even more crucial in these settings that acoustic controls are in place to allow for effective communication.
- The fatigue and lack of centration that excessive noise causes undoubtedly has an effect on workplace productivity. Add to this poor communication, high staff turnover, persistent cases of sick leave and stress and together you have a recipe for an unproductive work environment where poor acoustics has become an environmental stress.
