Overview

Hearing aids are incredibly effective at treating hearing loss, yet surprisingly few people who need them actually use them.

According to recent research, approximately 18 million people in the UK are affected by hearing loss, equating to more than a quarter of the population. However, only 2 million people in the UK use hearing aids, despite the significant number of those with hearing loss(Source: RNID).

Perhaps it’s the stigma that’s holding people back, but the reality is this: hearing aids can hugely improve your quality of life. From clearer conversations to reduced cognitive strain, the benefits far outweigh the perceived downsides.

One of the questions we hear most often from our patients is: “When should I get a hearing aid?” If you’re starting to wonder whether you’re one of the 5 million who could benefit from one, this article is for you.

 

Common signs you may need a hearing aid

You hear a ringing in your ears

Persistent ringing (or buzzing) in your ears, known as tinnitus, affects up to 15% of the population. It’s often a sign of underlying hearing damage. When sound-detecting cells in the ear are damaged or die, your brain compensates by generating phantom noise. If this sounds familiar, it might be time to get your hearing checked.

You can hear voices, but the words don’t quite make sense

This is often a subtle and easily missed early indicator of mild hearing loss. You hear sounds, but it feels like people are mumbling, speaking too quickly, or like the conversation’s happening from across the room. If you frequently ask others to repeat themselves, a hearing aid could help restore clarity.

 

You've had a head injury

Injuries to the head, whether from accidents, falls, or contact sports, can disrupt the delicate pathways that carry sound signals from your ears to your brain.

 

You struggle to work out where sounds are coming from

Our brains use tiny differences in how sound reaches each ear to pinpoint direction. If that process is off, it may signal hearing loss. If you often find yourself looking the wrong way when someone calls your name, that’s usually a red flag.

 

But do I really need a hearing aid?

It’s a common misconception that hearing aids are just for the elderly or profoundly deaf. In fact, they can help anyone with even a mild hearing loss.

Yes, they’re more common in older adults, 70% of over-70s have some level of hearing loss, but hearing loss doesn’t take into consideration how old you are. Around 15% of young people aged 6–19 already have measurable hearing loss, often due to things like loud music through headphones.

 

Who can benefit from hearing aids?

You might need a hearing aid if you fall into any of these groups:

Diagnosed with hearing loss: 

  • Ranging from mild to severe. 
  • Any type of hearing loss, such as conductive, sensorineural, or mixed.

 

Hearing loss at any age:

  • Children and teens with congenital or acquired loss.
  • Adults with hearing challenges at work or socially.
  • Older adults with age-related decline.

 

Specific needs:

  • Tinnitus sufferers.
  • Those concerned about memory or cognitive issues.

 

Struggles with everyday conversations:

  • Difficulties following chats at work, in restaurants, or with loved ones.
  • Feeling isolated due to hearing challenges.

 

Unfortunately, there's still a stigma attached to hearing loss and hearing aids.  A hearing aid doesn’t make you “old”; it simply means you’re taking care of your hearing health.  Today's hearing aids are sleeker, more discreet, and more advanced than they used to be. Some are nearly invisible, sitting inside the ear, and adapt to different environments automatically, and some include artificial intelligence (AI) to boost your listening experience when you need it the most.

 

Will hearing aids work for me?

In most cases, yes. About 95% of people with hearing loss see a significant improvement once fitted with the right hearing aid.  But here’s the catch: hearing aids need to be properly fitted and programmed by a professional audiologist. Treating all hearing loss the same just won’t work. Your success depends on an accurate diagnosis and personalised treatment.

That’s why a hearing test is essential. At Hearing Aid UK, we assess your hearing with expert technology to determine the exact nature of your hearing loss and recommend the best solution.

One hearing aid or two?

If your hearing loss is in one ear only (perhaps due to injury or infection), a single hearing aid may be enough.  Using just one hearing aid in this case may improve hearing in one ear, but your brain will still struggle to interpret sound direction and clarity. For more balanced, clearer hearing, two hearing aids are often the best and here's why...

Most people experience bilateral hearing loss, meaning it affects both ears. This is especially common with age-related hearing loss or conditions that impact the auditory system more broadly. In these cases, using just one hearing aid can leave your brain struggling to accurately process sound.

This is because your brain relies on input from both ears to localise sounds, filter out background noise, and maintain natural hearing clarity. Wearing only one hearing aid when both ears are affected can lead to an imbalance that makes it harder to focus on conversations, follow speech in noisy environments, or detect where sounds are coming from.

Wearing two hearing aids helps your ears to work together, providing a more natural, wider hearing experience. You’ll start to notice better clarity, improved spatial awareness, and less strain during conversations.  Think of it like wearing glasses, if both eyes need correction, you wouldn’t just use one lens. Your ears work the same way.

If you’re unsure whether one or two hearing aids are right for you, a hearing test with a qualified audiologist will help determine the best approach based on your own needs.

Why treating hearing loss matters

It’s important to understand the risks of ignoring hearing loss.  Studies now show a strong link between hearing loss and cognitive decline, including dementia. People with even mild hearing loss are said to have double the risk of developing dementia. For severe hearing loss, that risk increases by five times.

Why? One theory is cognitive load. Struggling to hear puts your brain under constant strain. It diverts mental energy from other tasks, which may speed up cognitive fatigue and decline.  Social isolation is another concern. Many people with hearing loss withdraw from social settings out of frustration or embarrassment.

This loneliness is not only damaging to mental health but also contributes to further cognitive decline.  Hearing aids can help prevent this. They make conversations easier, improve focus, and give you back the confidence to connect with others.

Is this the best hearing aid model for me?

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.

  • Audiologist level of knowledge: The audiologist you have seen will hopefully have a wide knowledge of all available hearing aids, however, some will only be familiar with a small number of brands and therefore may not really be in a position to know which model is the best for you. It is OK to challenge their recommendation and ask them to justify why this particular brand is the one for you.
  • Do research: Read about the hearing aid that was recommended. Does it seem like it will suit your lifestyle? Does it have more or fewer features than you need? 
  • Be aware of sales targets: Many high street retailers have specific tie-ins to a particular manufacturer/brand. The hearing aid they have suggested may still be the correct one for you, but do your research so that you know why they might have recommended it.

Do I need one hearing aid or two?

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.

What are the benefits of rechargeable hearing aids?

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.

Are behind the ear aids better than in the ear aids?

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.

What are channels, and how many do I need?

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.
