Hearing protection should be selected using the workplace noise assessment. Reduce noise at source where possible, then specify the protection needed for the remaining exposure.
Understand the exposure
Duration, noise level, frequency content and sudden peaks can all matter. A single spot reading or the name of a machine is not a complete assessment. Use competent advice where the exposure or selection is uncertain.
Read attenuation information correctly
SNR means Single Number Rating. It summarises test attenuation, while H, M and L values provide further information about performance across frequency ranges. Do not simply subtract the printed SNR from any noise reading and assume that is every wearer’s protected exposure.
Avoid choosing by the biggest number
HSE warns that excessive attenuation can interfere with communication and warning signals. Select suitable protection for the assessed conditions, rather than automatically ordering the highest SNR available.
Compare plugs and defenders
Consider fit, hygiene, the task and how long protection will be worn. Earplugs need correct insertion; defenders need an effective seal. Check compatibility with spectacles, helmets and other PPE, including the approved combinations for helmet-mounted products.
Train and maintain
Show users how to fit, check and care for their equipment. Follow the product instructions for cleaning, replacement and reusable components. Make the route to a replacement clear so damaged protection is not kept in service.
Confirm the purchasing brief
Record approved models, attenuation requirements, quantities and any communications needs. Electronic features do not remove the need to check protective performance. Keep the manufacturer’s information with the selection record and review the choice when the work or exposure changes.
