“Hearing loss can range from mild to profound and has many different causes, including injury, disease, genetic defects and the ageing process. Hearing loss at birth is known as congenital hearing loss, while hearing loss that occurs after birth is called acquired hearing loss. The most common cause of acquired hearing loss is noise, which accounts for over one quarter of people affected by hearing loss. You can protect your hearing by reducing your exposure to loud noise or wearing suitable protection such as ear muffs or ear plugs.”.
