The condition Colin is likely to be suffering from is Presbycusis. Presbycusis is an age-related hearing loss, it is a hearing disorder that can be caused by a variety of different factors. It is usually a sensorineural hearing disorder but can be a conductive hearing loss. A conductive hearing loss is when it is caused by problems with the ear canal, ear drum, middle ear and the malleus, uncus and stapes this can result in reduced function of the tympanic membrane or reduced function of auditory ossicles. Most commonly it is as a result of changes within the inner ear, middle ear or the nerve pathways to the brain. The cochlea is lined with tiny hair cells; these hairs convert sound vibrations into electrical signals which are received at the brain by a nerve. These cells can become damaged over time this means electrical signals cannot be transmitted as effectively so hearing becomes affected. Long-term exposure to loud noises such as that from traffic and loud equipment which Colin would have been exposed to working as a mechanic can also be a cause of …show more content…

Long-term noise exposure is an example; this is due to the damage that the noise exposure can have on the sensory hair cells. Sensory hair cells are what allow you to hear and if damaged the ability to hear is reduced and these hair cells do not grow back. As Colin was a car mechanic this meant he will have been in contact and close proximity to loud equipment and machinery daily, this could have had a detrimental effect to his hearing and prevented him from hearing Mary. Other environmental factors include ototoxic drugs, genetic factors and cell damage and neural degeneration which are common effects of aging. Ototoxic drugs can effect hearing as they can damage the inner ear including the hair cells and also the auditory nerve, this is important as it carries the sound information to the
