The noise exposure calculators can help you work out your daily noise exposure, weekly noise exposures, and estimate the performance of hearing protection.
If your version of Excel is having compatibility issues with the calculator then please see:
The noise exposure ready-reckoners allow you to estimate daily or weekly noise exposure. To use the daily exposure ready-reckoner you will need to know the levels of noise and durations of exposure which make up a person's working day. For weekly noise exposure, appropriate where somebody's noise exposure varies markedly from day to day, you will need to know the daily noise exposure for each day in the working week. These ready-reckoners can be printed for completion by hand.
