The need to ‘stop that noise’ is evident. Millions of Europe’s workers suffer from work-related hearing difficulties. Noise-induced hearing loss is amongst the most commonly reported occupational diseases in the European Union, and there are concerns other than hearing loss from noise exposure. Noise can also cause harm in other ways: it can interact with dangerous substances to cause harm to the ear; it can increase the risk of accidents by affecting communication. The range of jobs and workplaces where noise can be a problem is much broader than is commonly thought.
