Hearing loss can be something that happens suddenly if you’re exposed to a loud sound or bang. It can also happen slowly over a long period of time, which is often the case with age-related hearing loss. Understanding hearing loss is an important first step towards doing something about it.
Hearing loss means you have lost the ability to hear certain sounds. Maybe you can no longer hear high-pitched tones, like the voices of women or children. Or maybe you can’t pick out a single voice if there is a lot of conversation in the background.
Sometimes hearing loss is temporary, like a ringing in your ears after a noisy concert. Most often, it is permanent because the mechanisms that help you hear have been damaged.
Hearing loss can be divided into four categories depending on the level of hearing loss*: mild, moderate, severe and profound. Watch the video to understand these four levels better.*World Health Organization, 2016
