The GB Health and Safety Executive (HSE) has updated its noise exposure calculator to enhance its effectiveness in helping employers assess hearing protection in noisy environments.
Noise-induced hearing loss (NIHL) is a risk to health in many Jersey workplaces and work activities. The HSE’s noise calculator assists duty holders in assessing and controlling the risk to health from noise exposures.
NIHL is irreversible and can profoundly affect sufferers’ enjoyment of life.
The updated calculator features mobile compatibility and more precise calculations for hearing protection, including the HML (High, Medium, Low) method for improved accuracy. The original SNR (Single Number Rating) method remains available for users who prefer it.
The new version also helps identify over and under-protection, ensuring safety alarms remain audible where necessary.
