Before you go off saying their standards are different than ours, these EXCEL Spreadsheets can be modified using OSHA numbers/factors. These are just EXCELLENT TOOLS for those of you trying to establish if workers are exceeding the Action Level or PEL for noise exposures AND these tools will perform the “Hearing Protection Attenuation” evaluation for you. This attenuation evaluation is one of the most missed aspects of a Hearing Conservation Program and this tool makes it so much easier than doing it “long hand” using the 1910.95 appendix.
