Overview | The hearing range | What is profound hearing loss? | The causes | Getting diagnosed | Living with profound hearing loss | Conclusion
We all experience the world through our senses, and hearing is a big part of that. It connects us to people, helps us enjoy music, and keeps us aware of our surroundings. But what happens when hearing loss goes beyond just missing the odd word or two? Let's talk about profound hearing loss, a significant challenge, but one that people navigate every day.
Before we dive into the specifics of profound hearing loss, it's helpful to understand the different degrees of hearing loss first. Audiologists, the healthcare professionals who specialise in hearing, measure hearing loss in decibels (db). Think of decibels as a way to measure the loudness of sound.
Here's a general guide to the different types of hearing loss and the symptoms:

So, what does it really mean to have profound hearing loss? In simple terms, it means that you have very little or no functional hearing. Every day sounds that most of us take for granted, such as someone speaking at a normal volume, a phone ringing, or a car horn, are either not heard at all or are only heard as very faint vibrations.
The volume is turned down to almost zero. That's the reality for someone with profound hearing loss. It can make communication incredibly challenging and can affect many aspects of daily life.
Profound hearing loss can be present from birth or can develop later in life. There are several reasons why someone might experience this level of hearing loss:
Diagnosing profound hearing loss involves a thorough assessment by an audiologist. This assessment includes several key tests. Audiometry, the standard hearing test, involves wearing headphones and responding to sounds played at different frequencies and volumes.
In cases of profound hearing loss, the audiologist will be looking for responses to only the loudest sounds. Tympanometry checks the function of the middle ear and eardrum.
The Auditory Brainstem Response (ABR) test measures the electrical activity in the brainstem in response to sound and is often used for infants and young children, or when a more detailed assessment is needed.
Finally, the Otoacoustic Emissions (OAEs) test measures the tiny sounds produced by the inner ear, which are usually absent in cases of profound hearing loss.
Living with profound hearing loss can be challenging, but it's important to remember that people with profound hearing loss can and do lead full lives with the right support and treatment. Communication is key, and several tools and strategies can help:

For those with profound hearing loss, early intervention is so important. Profound hearing loss is a significant disability, but it doesn't have to be a barrier to a fulfilling life.
With the right support, technology, and communication strategies, people with profound hearing loss can connect with others, learn, work, and enjoy everything life has to offer.

If you are looking at this page then it is likely that an audiologist has suggested that you purchase this particular hearing aid, so is this the best model for you?
In general, any audiologist will always recommend to you the model that best suits your needs. Here is a useful checklist to make sure that is the case.

If you have significant hearing loss in both ears, you should be wearing two hearing aids. Here are the audiological reasons why:
Localisation: The brain decodes information from both ears and compares and contrasts them. By analysing the minuscule time delays as well as the difference in the loudness of each sound reaching the ears, the person is able to accurately locate a sound source. Simply put, if you have better hearing on one side than the other, you can't accurately tell what direction sounds are coming from.
Less amplification is required: A phenomenon known as “binaural summation” means that the hearing aids can be set at a lower and more natural volume setting than if you wore only one hearing aid.
Head shadow effect: High frequencies, the part of your hearing that gives clarity and meaning to speech sounds, cannot bend around your head. Only low frequencies can. Therefore if someone is talking on your unaided side you are likely to hear that they are speaking, but be unable to tell what they have said.
Noise reduction: The brain has its own built-in noise reduction which is only really effective when it is receiving information from both ears. If only one ear is aided, even with the best hearing aid in the world, it will be difficult for you to hear in background noise as your brain is trying to retain all of the sounds (including background noise) rather than filtering it out.
Sound quality: We are designed to hear in stereo. Only hearing from one side sounds a lot less natural to us.

For most people, the main benefit of a rechargeable hearing aid is simple convenience. We are used to plugging in our phones and other devices overnight for them to charge up. Here are some other pros and cons:
For anybody with poor dexterity or issues with their fingers, having a rechargeable aid makes a huge difference as normal hearing aid batteries are quite small and some people find them fiddly to change.
One downside is that if you forget to charge your hearing aid, then it is a problem that can't be instantly fixed. For most a 30-minute charge will get you at least two or three hours of hearing, but if you are the type of person who is likely to forget to plug them in regularly then you're probably better off with standard batteries.
Rechargeable aids are also a little bit bigger and are only available in Behind the Ear models.
Finally, just like with a mobile phone, the amount of charge you get on day one is not going to be the same as you get a few years down the line. Be sure to ask what the policy is with the manufacturer warranty when it comes to replacing the battery.

For most people, the answer is yes. But it's never that simple.
The majority of hearing problems affect the high frequencies a lot more than the low ones. Therefore open fitting hearing aids sound a lot more natural and ones that block your ears up can make your own voice sound like you are talking with your head in a bucket. Therefore in-ear aids tend to be less natural.
However the true answer is we can't tell until we have had a look in your ears to assess the size of your ear canal, and until we have tested your hearing to see which frequencies are being affected.
People with wider ear canals tend to have more flexibility, also there are open fitting modular CIC hearing aids now that do not block your ears.
There is also the age old rule to consider, that a hearing aid will not help you if it's sat in the drawer gathering dust. If the only hearing aid you would be happy wearing is one that people can't see, then that's what you should get.
Most people can adapt to any type of hearing aid, as long as they know what to expect. Have an honest conversation with your audiologist as to what your needs are.
Generally speaking, six or more. Unless it's none at all.
The number of channels a hearing aid has is often a simplistic way an audiologist will use to explain why one hearing aid is better than another, but channels are complex and it is really not that straightforward. Here are some reasons why:
Hearing aids amplify sounds of different frequencies by different amounts. Most people have lost more high frequencies than low and therefore need more amplification in the high frequencies. The range of sounds you hear are split into frequency bands or channels and the hearing aids are set to provide the right amount of hearing at each frequency level.
Less than six channels and this cannot be done with much accuracy, so six is the magic number. However, a six channel aid is typically very basic with few other features and is suitable only for hearing a single speaker in a quiet room. The number of channels is not what you should be looking at, it's more the rest of the technology that comes with them.
As a final note, different manufacturers have different approaches. One method is not necessarily better than any other. For example, some manufacturers have as many as 64 channels in their top aids. Most tend to have between 17 and 20. One manufacturer has no channels at all.
