Noise induced hearing loss and 'ringing in the ears' (Tinnitus) are common symptoms that arise when someone is exposed to prolonged and loud noise. As a rule of thumb a noise hazard may exist when two people need to raise their voices to hold a normal conversation when 2m apart. This code is relevant to all managers responsible for areas where noise is a hazard to staff, contractors and others.
The code establishes the role of a Noise Assessor who will undertake a noise assessment for managers responsible for noisy areas recommending remedial action and appropriate use of Personal Protective Equipment (PPE) as determined by the legally defined Lower and Upper Action Values, 80 and 85 dB(A) respectively. Where staff work in such areas regular hearing tests may be necessary, undertaken by local Occupational Health teams, to identify the early sign of damage to hearing.
