title: [Algorithms for adding and subtracting noise levels].
abstract: Nowadays 7% of Europe's workers suffer from work related hearing difficulties and noise induced hearing loss is among the most commonly reported occupational diseases in the E.U. In this situation the occupational health physician has to evaluate the noise level especially in industrial environment in order to help the patients and the employers to prevent the noise irreversible health damages. This material presents two simple algorithms to be used to calculate the resulting noise level when composing noise sources. Personal contributions.
