Occupational noise exposure often contributes to fatigue, tiredness, stress, and annoyance in exposed subjects. These conditions, if prolonged over time, can cause various extra-auditory effects. These effects, associated with sensory overload, may lead exposed people to pay less attention to sounds with important information content (alarms, verbal messages, etc.). The outcome could lead to a reduction in both working performance and safety itself, with potential accident triggering.

This study shows an encouraging result in the use of sound quality metrics and statistical analyses in order to correlate different acoustic descriptors and their role in the classification of the analyzed noise samples, which can be employed to outline a technical and scientific framework to improve the acoustic comfort in working environments and, therefore, to prevent working accidents.
