What you need to know about hearing loss

Hearing loss is a growing global health concern affecting people of all ages, according to the World Health Organization.

The condition occurs when a person is unable to hear as well as someone with normal hearing, which is defined as hearing thresholds of 20 decibels or better in both ears.

The WHO estimates that more than 1.5 billion people worldwide experience some degree of hearing loss.

Causes include ageing, exposure to loud noise, ear infections, certain diseases, genetic factors and the use of specific medicines that can damage hearing.

Hearing loss can affect communication, education and employment opportunities, and may lead to social isolation if left untreated.

However, many cases are preventable through measures such as avoiding prolonged exposure to loud sounds, using ear protection in noisy environments and ensuring early treatment of ear infections.

Early detection through regular hearing checks is important.

Treatment options include hearing aids, cochlear implants, rehabilitation and sign language support.
