Why hearing loss prevention matters

Occupational noise-induced hearing loss is the most common occupational disease in the world. But it is 100% preventable. 

Current hearing conservation approaches are ineffective for workers in dynamic noise environments. Traditional PPE provides no information about the level of protection being offered or the level of exposure to damaging noise. Workers are therefore not able to change their habits to reduce personal risk.

Minuendo overcomes these problems by automating the hearing loss prevention process, providing practical real-time guidance on noise exposure that helps adopt safer behaviour in industrial and construction environments.
