A common recommendation I have seen from Occupational Health Physicians has been ‘recommend wear double hearing protection’. What they are saying is that they recommend the person concerned wears two sets of hearing protection, usually a plug and a muff over the top, but to be honest, it is nonsense and usually has no link to the findings of the noise assessment.

There is no exemption from the need to wear hearing protection for forklift drivers. High noise will have the same impact on them as on any other person. Their hearing will still be damaged by noise.

Over-protection often comes from well-meaning employers buying the strongest hearing protection they can find - hearing protection with the highest SNR. They mean well but it often actually increases risk and for the employer, means more of the money they spend on hearing protection is wasted.
