Demonstrative tool to compute a worker’s daily personal noise exposure level LEX,8h, from one or more shifts with distinct level and duration plus the peak level L_Cpeak. It applies LEX,8h = 10·log₁₀[(1/8)·Σ Te·10^(LAeq/10)] and returns the Italian D.Lgs 81/08 band relative to the action values and the limit value, with the related preventive measures and a per-shift contribution table.
