Hearing is one of the most important senses in the human body and is the result of a complex biological structure made up of several components. These components work together to convert soundwaves into information that can be interpreted by the brain.
Whilst the process of hearing is quite complex, breaking it down into smaller components will help us understand the basics of how your brain interprets the sound waves that are happening around you.
The role of the outer ear is to collect sound waves from your surrounding environment and direct them into the eardrum.
When sound reaches the eardrum, it begins to vibrate.
Once these soundwaves reach the eardrum, the ossicles, which are the small bones in the middle ear, also begin to vibrate.
As the vibrations continue through the ear canal, they, then, reach the cochlea which has both fluid and tiny hair cells, which create signals that are picked up by the auditory nerve.
The auditory nerve’s role is to transmit the vibrations that are occurring in the ear and, in turn, send these signals to the brain’s hearing centres which then interpret the signals as either sounds or speech.
As you can see, hearing is made up of several different steps that involve various parts of the ear and the brain. When any of these parts are not functioning properly, or are impeded by an external factor such as a blockage or damage, hearing loss may result. These causes of hearing loss can be genetic, caused by illness, physical damage or environmental.
Broadly speaking, hearing loss can be broken down into five primary categories:
Conductive hearing loss is the result of a physical condition that has affected the proper working of a component of the outer or middle ear which is stopping or interfering with sound reaching the inner ear and eventually, the hearing centres of the brain. Common causes of conductive hearing loss may include but are not limited to, a blockage in the outer ear canal such as wax or another obstruction, an ear infection which is causing swelling, and an excess of fluid in the outer ear or any other malformation of the outer ear canal. Conductive hearing loss, in most cases, can be treated with medication or medical procedures and in cases where this is not possible, patients often find that their hearing can be significantly improved with the use of hearing aids or other hearing devices.
Sensorineural hearing loss (sometimes referred to as SHL) is most often the result of a problem that is stopping the cochlea from functioning properly. This can either be from genetic conditions which have caused a malformation of the cochlea itself, or as a result of damage to the cochlea which can be caused by physical damage, or infections such as meningitis. For people who have SHL, hearing can often be improved through the use of various hearing devices, including hearing aids, middle ear implants or cochlear implants. The type of treatment that would be recommended depends on the cause and severity of the patient's condition.
As previously mentioned, hearing loss can be the result of multiple problems with the ear structure. Mixed hearing loss occurs when a combination of conductive and sensorineural factors are impacting the patient. Again, the recommended treatment may change depending on the cause and severity of the problem.
Neural hearing loss is a rare condition that is the result of either malformation or damage to the auditory nerve. When working properly, this nerve connects the cochlea and the brain and allows the interpretation of sound. Neural hearing loss is not usually treatable with hearing aids or devices.
In clients with Auditory Neuropathy, sound travels normally through the various components of the outer and inner ear. However, further transmission of these signals to the brain is impaired. This condition affects all walks of life, including babies, children, and adults. The impact of hearing may widely vary.
Whilst hearing loss can be more common as we age, anyone can be affected by hearing loss at any time. When hearing loss happens after birth, we refer to this as acquired hearing loss. Acquired hearing loss can be the result of many common factors such as chronic ear infections, ototoxic drugs, other diseases such as meningitis, head injury, or the eardrum becoming perforated by a physical impact.
Also, prolonged exposure to high volumes can impact your hearing health. Workers in certain industries where loud noise is common, such as manufacturing or construction, often present with acquired hearing loss.
If you or your loved one are experiencing any level of hearing loss, or have concerns regarding your hearing, you should speak to a hearing healthcare professional. Modern technology has come a long way in both the hearing testing process, diagnosis of hearing loss, and on-going hearing loss treatment, such as hearing aids or other hearing health devices.

A hearing aid is a device worn behind the ear, in the outer ear canal, or in the middle ear to amplify sounds. It can be used to improve mild to moderately-severe losses due to sensorineural hearing impairment and conductive hearing impairment. Some hearing aids also have a built-in T-coil (telecoil) which can be used to improve the listening experience for people with single-sided deafness, or when there is a lot of noise present.
Hearing aids make it possible for people with mild to severe hearing loss to hear sounds more clearly. There are different types of hearing aids that can be used in either one or both ears.
A digital hearing aid is an electronic device that amplifies sound. Digital hearing aids convert sound waves into electrical signals that are then amplified. This type of hearing aid is a more modern technology offering greater benefits to users.
If you have trouble hearing, or if people complain that you're turning the TV volume up too high, you may need a hearing aid. A hearing test can confirm whether you have a problem.
Your audiologist will help you choose the type of hearing aid that's best suited for your needs and lifestyle. Factors that will be considered include the severity of your hearing loss, your listening environment, and your budget.
The four main types of hearing aids are:
1. Behind-the-ear (BTE)
This is the most common type of hearing aid. It sits behind the ear and has a clear plastic tube that goes down into the ear canal. BTEs are available in a variety of styles and colors, and are the most durable type of hearing aid.
2. In-the-ear (ITE)
This type of hearing aid is custom made to fit snugly in the outer part of your ear. ITEs are less visible than BTEs, but they may not be as durable.
3. In-the-canal (ITC) and completely-in-the canal (CIC)
These are the smallest and most discreet type of hearing aid. ITCs and CICs sit in the ear canal and are not visible once they are in place. They can be more difficult to adjust than other types of hearing aids.
4. Invisible Hearing Aid (IHA)
An invisible hearing aid is designed to be worn for extended periods of time to minimise the hassle of managing your hearing health. The devices are inserted deep into the canal, by a qualified Audiologist and remain there for their lifecycle.
The different parts of a hearing aid include:
1. The microphone
This is the part of the hearing aid that picks up sound from the environment.
2. The amplifier
This part of the hearing aid increases the volume of sound that is picked up by the microphone.
3. The receiver
This is the part of the hearing aid that sends sound to your ear.
4. The battery
This powers the hearing aid. Hearing aids use either disposable or rechargeable batteries.
5. The processor
This controls how the hearing aid sounds and adjusts to different environments.
6. The casing
This is the outer shell of the hearing Aid.
There are many different features that you can choose from when you buy a hearing aid. Some common features include:
1. Volume control
This lets you adjust how loud or soft the sound is coming through the hearing aid.
2. Tone control
This allows you to adjust the tone of the sound, making it sound more natural.
3. Noise reduction
This feature reduces background noise, making it easier to hear conversation.
4. Directional microphones
This feature allows you to adjust the hearing aid so that it picks up sound from the front, making it easier to hear in noisy environments.
5. Telecoil
This is a special setting that helps you hear better on the telephone and in places where there is a loop system set up (such as a movie theatre or museum).
There are two main types of hearing loss: conductive and sensorineural.
1. Conductive hearing loss
This type of hearing loss occurs when there is a problem with the structure of the ear or the way that sound waves are conducted through the ear. Conductive hearing loss can be caused by things like wax build-up, infection, or damage to the ear.
2. Sensorineural hearing loss
This type of hearing loss occurs when there is a problem with the inner ear or the way that the brain interprets sound. Sensorineural hearing loss can be caused by things like age-related hearing loss, noise exposure, or injury.
There are many benefits to using a hearing aid. Some of the most important benefits include:
1. Improved communication
Hearing aids help you hear better in both quiet and noisy environments, making it easier to communicate with others.
2. Improved quality of life
Hearing aids can help you stay connected to your loved ones and participate in activities that you enjoy.
3. Improved safety
Hearing aids help you hear warning signals and other important sounds, making it easier to stay safe in your environment.
4. Improved mental health
Research has shown that using a hearing aid can improve your mood and overall well-being.
5. Improved self-confidence
Using a hearing aid can help you feel more confident and social, which can lead to a better quality of life.
6. Reduces the risk of developing dementia
Research has shown that using a hearing aid can reduce the risk of developing dementia by up to 50%.
7. Reduces the risk of falling
Hearing aids help you hear better in your environment, which can help you stay safe when walking or climbing stairs.
8. Reduces the risk of social isolation
Hearing loss can often lead to social isolation, but using a hearing aid can help you connect with others and stay involved in your community.
9. Affordable
Many health insurance plans cover the cost of hearing aids, making them more affordable for those who need them.
10. Customizable
Hearing aids come in many different styles and colours, so you can find one that fits your personality and lifestyle.
We all know that hearing loss can cause many problems. It can be a serious issue for those who work in noisy environments, in the office or on the construction site, or an inconvenience for someone wanting to tune into their favourite TV show. If you have any of the following symptoms, it is time to schedule an appointment with your audiologist:
Any noticeable change in your hearing
You have a hearing loss that is severe enough to interfere with your life
You have tinnitus
You have sudden and unexplained hearing loss
You are not able to hear a conversation from across the room or in a quiet room
You are missing conversations on your Phone or in the car
You experience dizziness, vertigo, or ringing in the ears
If you are experiencing any of these symptoms, it is important to schedule an appointment with your audiologist. The sooner you get treatment, the easier it will be to manage your symptoms and the less they will impact your life.
There is no evidence to suggest that properly fitted hearing aids can cause vertigo. However, if you are experiencing vertigo or other dizziness-related symptoms, it is important to speak with your audiologist. There may be another underlying cause for your symptoms that needs to be addressed.
Hearing aids do not need to be replaced on a regular basis. However, over time they may start to lose their effectiveness or become damaged. If you notice that your hearing aids are not working as well as they used to or if they are damaged, it is important to see your audiologist for a replacement.
There is no evidence to suggest that properly fitted hearing aids can cause headaches. However, if you are experiencing headaches, it is important to speak with your audiologist. There may be another underlying cause for your symptoms that needs to be addressed.
Most hearing aids are not completely waterproof, but most models come with a water-resistant coatings that can protect them from light rain or accidental exposure to water. It is important to remove your hearing aids before swimming or showering.
