- Protect the employees directly with ear defenders.
- Limit the time spent in noisy areas.
How bad is noise pollution?
Noise pollution significantly impacts public health. Research suggests it can raise stress, affect mental health, and contribute to developing health issues such as high blood pressure. Direct exposure to loud or persistent noise can also lead to hearing impairment.
What is physical noise?
