Deafness: many can be prevented.

World Health Organization (WHO) estimates that the world has 360 million deaf people. Exposure to loudness of above 85 decibels for 8 hours is unsafe. Traffic noise can reach 95 decibels. Continued exposure to modern noises such as loud music means the number of deaf people may reach over 1 billion.
