Every year, March 3 is observed as World Hearing Day. The day is observed to raise public awareness about how to avoid deafness and hearing impairment, as well as to support ear and hearing care around the world.

According to the World Health Organization (WHO), ear and hearing problems are among the most common problems encountered in the community.

In shocking reports, the WHO claims that by 2050, about 2.5 billion people are projected to face some degree of hearing loss, and around 700 million people will require hearing rehabilitation.

Many people have undiagnosed hearing problems, and are unaware that they are missing out on important sounds and phrases. The first step in dealing with the problem is to assess one’s hearing. But, surprisingly, over 60% of these can be identified and addressed at the primary level of care.

7. Public health efforts can help prevent over 60% of hearing loss cases involving children.
