Types of Hearing Loss: Causes, Signs, and Treatments

What is Hearing Loss?

Hearing loss means you cannot hear sounds as well as most people. It can happen to anyone, at any age. Often, it develops slowly. However, sometimes it can happen suddenly. There are different types of hearing loss, and each type has its own causes and treatments. According to the World Health Organization (WHO), over 5% of people worldwide have some hearing loss.

Main Types of Hearing Loss

There are three main types of hearing loss. Each type affects the ear in a different way. Understanding these types can help you know what to expect.

Conductive Hearing Loss: This type happens when sound cannot reach the inner ear. It often involves problems in the outer or middle ear.

Sensorineural Hearing Loss: This type happens when there is damage to the inner ear or the nerve that sends sound to the brain.

Mixed Hearing Loss: Sometimes, both conductive and sensorineural hearing loss happen together. This is called mixed hearing loss.
