What Causes Hearing Loss and How to Avoid It

The problem of hearing loss is quite prevalent, and it can be found in people from all age groups; however, the majority of them still consider it to be an unavoidable consequence of aging or just a matter of noisy environments. In reality, the situation is far more complex, as there are numerous origins of hearing loss, some of which are preventable and others not.

The knowledge of what can harm hearing and which risk factors can be controlled gives the person the power to make informed choices that will keep the auditory system healthy for the rest of their life. 

Noise Exposure Tops the List

The most common and avoidable cause of hearing loss is excessive noise exposure, which can result from workplaces, leisure activities, and even residential areas, affecting individuals across all age groups. The loud noises damage the delicate hair cells in the inner ear that are responsible for converting sound waves into electrical signals that the brain interprets. 

The damage is done by both short-term heavy exposures, like gunshots and concerts, or by long-term exposure to moderately loud environments. A good understanding of noise levels that are safe will help with prevention, with 85 decibels considered risky for prolonged exposure and 120 decibels potentially leading to immediate hearing loss.

Changes Related to Age 

In a slow manner, presbycusis, or senile hearing loss, gets worse as the hearing system changes its characteristics gradually over the years as we age. The inner ear’s hair cells will progressively die at an older age, with the loss of high-pitched sounds being the first sign, and later, other pitches get involved. 

Aging cannot be stopped, but lifestyle can influence the rate and severity of hearing loss due to age. Noise protection is one of the factors contributing to slowing down the process of age-related changes. 

Diseases and Drugs

Some health conditions, like diabetes, heart conditions, and treatments, can make the body suffer, and as a result, the patient loses his/her hearing. These diseases all impair the blood supply to the inner ear, the possible result of which is a gradual hearing loss. 

Autoimmune diseases sometimes hit the hearing system straight away, ushering in either sudden or gradual deterioration of hearing. Certain medications, referred to as ototoxic drugs, are known to affect hearing and the structures involved; these include some antibiotics, chemotherapeutic agents, and aspirin in large quantities.

Ear Infections and Physical Damage

Chronic ear infections can still lead to hearing defects because they may first destroy the tympanic membrane or then the small bones that compose the middle ear and transfer sound. A series of infections in early childhood is sometimes the reason for the prescription of fluid drainage or prolonged use of antibiotics that eventually leads to hearing impairment. 

Bashful or careless trauma inflicted on the head or ear can do one of the following: perforate the eardrum, unseat the middle ear bones, or affect the inner ear’s tissues. 

Lifestyle Choices Make a Difference

The habit of smoking adversely affects all blood vessels in one’s body, including the small ones that provide the inner ear with oxygen and other nutrients. Quite a few smokers suffer from permanent hearing loss compared to non-smokers, and the risk becomes higher the more cigarettes one smokes. 

Drinking large amounts of alcohol has a similar effect on hearing, besides affecting the brain’s central auditory processing centers.  Intentionally leading a healthy life that includes eating fruits, vegetables, and nuts will keep the hearing sense healthy, while a lack of some essential nutrients has been associated with increased hearing loss risks. These are necessary for maintaining healthy hearing.

Take Action to Prevent Hearing Loss

To avoid hearing loss, the first step is to be conscious of it, and the next step is to keep on practicing protective methods regularly. The use of earplugs or earmuffs in noisy places, maintaining personal audio at safe levels, controlling chronic health issues, and not smoking all extend the lifetime of hearing.
