Posted By The toecap Does anybody have a copy of a spreadsheet that can work out noise levels. With respect to duration of exxposure sound pressure levels etc. I knoe hse have got one but it doesn't quite hit the mark. I have a full copy of the Noise regs and have been reading thorugh loads of stuff that i'd like to compare.

Posted By Smurfer look at Example 4 of Appendix 3 of L108 "Reducing noise at work : guidance on the Noise at Work Regulations 1989". It gives examples of how to do exactly what you're trying to achieve.
