[Issues concerning the measurement and assessment of noise in workplaces].

The measurement and assessment of noise in workplaces are affected by several critical aspects. Only the equivalent sound pressure levels are measured and all the other acoustical parameters are almost always neglected; the non-acoustic information that characterize each measurement are not usually reported. The survey about noise in workplaces is not suited to be described by technical standards, but rather by flexible guidelines. The reference standard UNI EN ISO 9612/2011 does not highlight the contribution given by each work phase to the overall exposure level; the uncertainty evaluation may lead to unreliable data.
