A loss of hearing occurs as a result of the aging process. It is caused due to a gradual degeneration of the inner ear that occurs as we get older. While age-related hearing difficulties are not as dangerous as some other forms of illnesses, they can have a significant impact on the daily life of the sufferer. The problem can lead to issues with communication between an elderly person and their caregiver, which could lead to misunderstandings regarding when to take medication or how to manage pre-existing health issues. In some cases, the hearing difficulties may lead the person to withdraw from society due to a lack of self-esteem, or even potentially resulting in stress and depression.
The condition arises due to the cochlear hair cells of the inner ear deteriorating with age, with the with the cochlear hair cells often being the first to be affected. The older we get, the less we are able to hear high frequency sounds. With time, these hearing difficulties become more pronounced until mid-range frequencies, such as speech, also become harder to hear. All of this means that the elderly often cannot hear clearly, with the symptoms gradually worsening with age. Two other potential factors that quicken cochlear degeneration are some forms of medication and chronic health disorders, including diabetes, high blood pressure and hyperlipidemia. Also, in cases where the condition is neglected, hearing difficulties could end up leading to a serious loss of hearing.
Hearing loss refers to a reduction in hearing capabilities, which decreases in various levels, and are categorized as follows:
| Audible sounds | Severity level |
| Can hear speech at 0-25 decibels | Normal |
| Unable to hear whispers but can hear sounds from 26-40 decibels. | Slight loss of hearing |
| Unable to hear speech at normal volume, only able to hear from 41-55 decibels and above. | Moderate loss of hearing |
| Unable to hear speech even when that person is talking more loudly than normal. Only able to hear at 56-70 decibels and above. | Significant loss of hearing |
| Unable to hear shouting. Only able to hear sounds from 71-90 decibels and above. | Severe loss of hearing |
| Only able to hear anything at 91 decibels and above. | Deaf |
As there is currently no medication capable of treating age-related hearing loss, cases where the loss of hearing begins to have a negative effect on the life of the sufferer may require doctors to consider the installation of a hearing aid, which can act as an amplifier for the sounds around them. The hearing aid is installed into the ear itself but can be removed where necessary. However, where the hearing loss is more severe or the patient is effectively deaf, doctors may consider surgery to install a cochlear implant into the inner ear.
If symptoms consistent with age-related hearing loss are just beginning to present themselves, the elderly person should be especially careful to be gentle on their ears, including regularly attending doctor’s appointments focused on testing their hearing levels. Furthermore, loud spaces should be avoided, any chronic disorder with the potential to accelerate hearing loss risk should be carefully managed, and ear drops that have not been prescribed by a doctor should not be used under any circumstances. Regular exercise, a healthy diet consisting of the 5 main food groups in moderation, sufficient rest and practicing mental wellbeing call all go a long in protecting against age-related hearing loss.
