Recent studies in Europe and North America have shown a consistent prevalence of around 0.1% of children with a hearing loss of more than 40 decibels. In 2009 research data showed that over 97% of newborns in North America were screened for hearing loss. There was also a considerable increase in the number of infants screened for hearing loss (from 46.5% in 1999 to 97.0% in 2007).
Causes
It's been found that genes are one of the most important factors leading to hearing loss among 50% to 60% of children. Infections during pregnancy, complications after birth and other environmental causes are also responsible for hearing loss among approximately 30% of babies.
Some people lose their hearing slowly as they age. Aging is the cause of hearing loss in more than 25% of people over the age of 65. Many people are already showing the first signs of hearing loss in their 30s and 40s.
Exposure to too much loud noise is another popular reason for hearing loss. This condition is commonly known as noise-induced hearing loss. Often construction workers, farmers, musicians, tree cutters, etc. experience problems with hearing because of too much exposure to loud noise.
Other common causes for hearing loss may also include bacteria, heart conditions, strokes, head injuries, tumours or even certain medicines.
Treatments
Hearing health begins with hearing screening at birth. The first three years of a child's life are key to their lifelong communication abilities so it's important to monitor their hearing from an early age. As children move towards adolescence, developing healthy hearing habits like wearing earplugs in noisy environments is crucial to protecting their hearing.
Other treatments depend largely on a hearing problem you have. People with different degrees of hearing loss usually wear hearing aids. They're available in a wide range of styles, sizes and features; they make sounds louder while eliminating or lowering other noises around you. Just like earplugs, they can be custom-built for the user, based on their hearing level, lifestyle and individual needs.
Although hearing loss is permanent, it can still be prevented. Adopting safe listening habits from a very young age can help protect your hearing from long-term harm.
