Compared to what happens for other risk classes, the cause-effect terms that produce noise damage are not immediately visible. This means that, at times, the symptoms generated by exposure to noise are underestimated.
However, the health effects are numerous and varied: from reduced hearing ability to total hearing loss; involvement of central and peripheral neuroregulatory systems (cardiovascular system, endocrine system, central nervous system and others).
Noise also disrupts verbal communication and the perception of acoustic safety signals, causing mental fatigue, reduced efficiency in work performance and interference with sleep and rest.
It is therefore essential to prepare a professional acoustic impact assessment aimed at the conditions of the specific workplace.
