Closing the gap between 'the SNR says on the tin' and real-world hearing protection!
Hearing protection is often a kneejerk solution to a noise exposure problem. Indeed it is a mandatory requirement (above certain action levels) but we know that in terms of the hierarchy of controls, it is the least effective (control method) requiring the most supervision. And in reality there's a gap between what manufacturers state as the product's SNR value and real-world hearing protection. This gap is over and above the 4dB derating that the HSE already recommend is applied. In previous reports the HSE have even said that in some cases the wearer gets no protection whatsoever! Their most recent campaign has also highlighted other shortcomings and have been promoting the CUFF methodology to improve outcomes. Revised standards have also been published and this presentation will look at the issues in more detail with a suggested way to close the gap.
