As we get older our hearing inevitably declines, this is known as Presbycusis. The most common type of Sensorineural Hearing Loss, Presbycusis is caused by the natural ageing of our auditory system. Occurring gradually, it initially affects our ability to hear higher pitched sounds and eventually leads to the inability to hear a larger range of noises. There is little that can be done to prevent this type of hearing loss as it is a normal part of ageing for many, however with early treatment such as the fitting of hearing aids, the symptoms can be vastly improved and decline slowed, so that quality of life can be maintained.
