What Causes Hearing Loss & Can You Cure It?

Causes Hearing Loss

Finding out that you or a loved one has hearing loss can be emotional. You may be wondering what the cause of it was and whether it was something that could’ve been prevented. You may also be wondering whether it’s only temporary or permanent. 

Although some cases of hearing loss may be unknown and unable to be determined, most cases of hearing loss can be related to a known cause. 

Therefore it’s important to know what these causes are and the signs and symptoms to look out for. 

Today, we will be discussing the main causes of hearing loss and what you can do to cure it. 

Hearing Loss

Hearing loss is diagnosed in a person when their measured hearing thresholds are recorded as below normal in one or both ears.

Normal hearing limits are any frequency 20 decibels or lower. Hearing loss is scaled with its severity level, as it can be mild, moderate, severe or profound. It may be across some frequencies or all. 

Causes of Hearing Loss

There are many known causes of hearing loss, and it’s important to be aware of the signs and symptoms. 

Below we have outlined the six most common causes of hearing loss. 

Wax build-up

Wax build-up 

One of the most common causes of hearing loss is the buildup of wax, which may block the ear canal and prevent sounds from getting through. 

With a wax build-up, an individual may feel that their hearing is muffled and blocked. 

This cause of hearing loss is often quickly resolved by getting the ears cleaned out and wax removed by a doctor or audiologist. 

Middle ear infection

Another cause of hearing loss can be middle ear infections, fluid in the middle ear area, or a hole in the eardrum (commonly found in young children). 

It’s estimated that up to 80% of children may experience at least one ear infection in the first few years of their life, which may be behind the cause of hearing loss for that person. 

The good news is that this cause of hearing loss is often treatable with antibiotics, medical monitoring or sometimes surgery.

Noise exposure

Another common cause of hearing loss is due to noise exposure. 

Exposure to loud levels of noise, particularly constant noise (heavy machinery, loud music levels, recreational shooting), can damage the tiny hair cells in your inner ear.

As well as being a cause of hearing loss, loud noise exposure can also cause tinnitus, which can become quite debilitating for some people. 

Using hearing protection, being aware of a safe listening environment, and reducing noise exposure are important to reduce this cause of hearing loss. 

Noise-induced hearing loss is considered a permanent hearing loss, with hearing aids often recommended to improve one’s quality of life.

Inner and middle ear conditions 

Certain inner and middle ear conditions can cause hearing loss. Some of these conditions may be hereditary, while others aren’t. 

In some cases, the hearing loss may present alongside other symptoms, such as dizziness, tinnitus or pressure and fullness in the ear. 

It’s therefore important that these side symptoms are also recognised and investigated. 

Depending on the diagnosis of the hearing loss, some treatment options may include surgery, medications and treatment with other allied health professionals, such as physiotherapists and neurologists and assistance with hearing aids. 

Anatomy of the EarHead injury 

A head injury or damage to the brain can also cause hearing loss. 

If you notice a change in your hearing, including a change in hearing ability or interpreting speech, or if you have a sudden onset of ringing in the ear, it’s important to get it checked by a doctor or audiologist. 


Perhaps the most common and well-known cause of hearing loss is age. 

As a person gets older, their hearing thresholds will naturally decline. By the age of 65, hearing loss has been shown to affect one in three people.

Given the ageing population, many people live with hearing loss, with age being the main cause. 

If diabetes or high blood pressure is diagnosed, it’s even more common to experience this cause of hearing loss. 

Age-related hearing loss is a gradual loss that results from irreversible changes in the inner ear. 

Treatment for this cause of hearing loss, in most cases, is hearing aids, assistive listening devices, communication tactics and, sometimes, implantable hearing devices.

In A Nutshell 

There are many causes of hearing loss, and if left untreated, it can lead to reduced quality of life. 

Depending on the cause of hearing loss, treatment options can range from surgical and medical interventions to hearing aids and listening devices.
