Under the Control of Noise at Work Regulations 2005 the aim is to ensure workers’ hearing is protected from excessive noise at their place of work, which could cause them to lose their hearing and / or to suffer from tinnitus. The level at which employers must provide hearing protection and hearing protection zones is 80 decibels and the level at which they must assess the risk to workers’ health and provide them with information and training is now 80 decibels.
