Overview

One of the most underappreciated features of modern hearing aids is spatial awareness, which is the ability to know where sounds are coming from.

If you've been struggling with hearing loss, you might have noticed it's not just about hearing sounds clearly; it's about knowing where they're actually coming from. This matters far more than most people realise, let's find out why...

 

What is spatial awareness?

When you have normal hearing, your brain is constantly processing subtle differences between what each ear hears to work out where sounds are coming from.

Someone calls your name from behind, and your brain instantly knows. A car approaches from your left, and you're aware of it before you even turn your head.

This is fundamental to how we navigate the world safely and naturally. Hearing loss disrupts this spatial awareness, and traditional hearing aids haven't always been particularly good at restoring it.

 

Why it matters for safety

Being able to locate sounds isn't just about having a pleasant listening experience; it's actually about safety.

Traffic approaching from the side, someone calling out a warning, a bicycle bell ringing behind you, are all situations where knowing the direction of sound could prevent an accident.

If you've been wearing hearing aids that amplify sound but don't preserve spatial cues, you might have experienced this unsettling feeling of hearing something but not quite knowing where it's coming from.

It can make you feel less confident when you're out and about, particularly in busy environments.

 

How spatial awareness works naturally

Your brain is remarkably clever at working out sound location. It uses three main cues: timing differences (sound reaches one ear slightly before the other), volume differences (sound is slightly louder in the ear closest to the source), and frequency differences (your head creates a "sound shadow" that affects higher frequencies more than lower ones).

When both ears work together properly, your brain processes all this information instantly and automatically. You don't think about it, you just know where sounds are coming from.

Hearing loss disrupts these natural cues, and the challenge for hearing aid manufacturers has been to preserve them whilst amplifying sound.

 

Modern hearing aids and spatial processing

Modern hearing aids have become significantly better at maintaining spatial awareness. For example, premium hearing aids now feature sophisticated spatial sound processing that works to preserve the natural cues your brain relies on.

Rather than simply amplifying sound equally in both ears, advanced hearing aids process sound in ways that maintain the subtle differences between ears. This means your brain can still work out where sounds are coming from, even though you're wearing hearing aids.

Some hearing aids feature what's called "spatial awareness technology" or "3D sound processing"; this is because different manufacturers use different names. 

The reality is that they're all working towards the same goal, creating hearing aids that communicate with each other wirelessly to ensure they're processing sound in a coordinated way that preserves directional information.

 

The benefits

Good spatial awareness makes a genuine difference to daily life, as you can follow conversations in group settings more easily because you know who's speaking.

You feel safer crossing roads because you can locate approaching traffic, and you're less startled by unexpected sounds because you know immediately where they've come from.

It also simply reduces listening fatigue. When your brain doesn't have to work as hard to locate sounds, the whole experience of wearing hearing aids becomes less exhausting.

This is particularly noticeable in busy environments where multiple sounds are competing for your attention.

 

The binaural advantage

This is where wearing two hearing aids becomes particularly important, as spatial awareness relies fundamentally on having input from both ears.

If you've got hearing loss in both ears but you're only wearing one hearing aid, you're missing out on the spatial processing benefits entirely.

Two hearing aids working together can create what audiologists call a "binaural advantage", which is when your brain gets the information it needs from both sides to work out sound location properly. It's not just about hearing twice as well; it's about hearing naturally.

What to look for

If spatial awareness is important to you, so try looking for hearing aids that specifically mention spatial sound processing or 360-degree sound awareness in their specifications. Ask your hearing care professional to demonstrate the difference during your consultation.

Premium hearing aids from manufacturers like Oticon, Phonak, and Signia all offer sophisticated spatial processing capabilities. However, the technology varies between manufacturers, but they're all working to preserve the natural spatial cues that help you locate sounds.

 

Would you benefit?

Spatial awareness is particularly valuable for people who lead active lifestyles and regularly find themselves in varied listening environments.

If you're frequently outdoors, in busy public spaces, or in situations where you need to be aware of your surroundings, spatial processing should be a priority.

It's also important for anyone who feels that their hearing loss has affected their confidence or independence. Being able to locate sounds properly can genuinely help you feel more secure and capable in the world.

 

Key takeaways

More than you'd think - Knowing where sounds come from is fundamental to safety and natural hearing

Critical for safety - Locate approaching traffic, warning calls, and potential hazards around you

Requires both ears - Spatial processing only works effectively when wearing two hearing aids (binaural advantage)

Modern technology preserves cues - Premium hearing aids maintain the timing and volume differences your brain needs to locate sounds

Reduces listening fatigue - Less mental effort when your brain doesn't have to work hard to locate sounds

Ideal for active lifestyles - Particularly valuable if you're frequently outdoors or in varied listening environments

Underappreciated feature - Not flashy, but essential for confident, independent, and natural hearing

 

Conclusion

Spatial awareness isn't a flashy feature that hearing aid companies can easily market, but it's one of the most important aspects of natural hearing.

Modern hearing aids that preserve spatial processing don't just help you hear better; they also help you hear more naturally, more safely, and with less effort.

If you're considering hearing aids or thinking about upgrading, spatial awareness deserves to be high on your list of priorities. Ask your audiologist about it, and make sure any hearing aids you trial are programmed to take full advantage of their spatial processing capabilities.

FAQs

What is the best hearing aid model for me?

In general, any audiologist will always recommend to you the hearing aid model that best suits your needs. Here is a useful checklist to make sure that is the case.

  • Audiologist's 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 them 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's warranty when it comes to replacing the battery.

Are Behind-the-Ear hearing aids better than In-the-Ear hearing 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 is 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.

What's covered in a manufacturer's warranty?​

Manufacturer's warranties typically last between 2-5 years, depending on the brand and model, and cover defects in materials and workmanship. This includes repairs for component failures, electronic malfunctions, and manufacturing defects, but excludes damage from misuse, accidents, or normal wear. Most manufacturers also include loss and damage insurance for the first year.

We handle all warranty claims on your behalf, liaising with manufacturers and ensuring you get replacement devices quickly when needed. This comprehensive warranty coverage, combined with our lifetime aftercare, gives you complete peace of mind.

How much does the hearing test cost?

Our hearing tests are completely free, whether at our clinics or in your home. Unlike other providers who charge £30-£100 for home visits, we believe hearing healthcare should be accessible without financial barriers. Our comprehensive assessments include examination by a registered audiologist, audiogram results, and personalised recommendations.

All testing, future adjustments, and ongoing support are included at no extra cost. While NHS tests are also free, typical 6-week waiting periods often lead people to seek immediate private testing. We provide prompt, professional assessments that fit your schedule and budget.

Do you offer home visits, and are they included in the price?

Yes, we offer completely free home visits throughout the UK, and this service is included in our prices with no additional charges. Home visits are particularly valuable for people with mobility issues, busy schedules, or those who simply prefer the comfort and convenience of their own environment.

Our audiologists can conduct full hearing tests, fit hearing aids, and provide ongoing support in your home.  This service sets us apart from many providers who either don't offer home visits or charge extra for them.

Why are your hearing aids cheaper than what I'd pay on the high street?

We can offer prices up to 40% lower than high street retailers because of our business model. As a network of 200+ independent audiologists, we don't have the massive overheads of large retail chains - no expensive high street premises, no sales targets pushing audiologists to sell the most expensive options, and no costly marketing campaigns.

However, we maintain the same buying power as the big chains because we purchase on behalf of our entire nationwide network. This means you get access to the same premium hearing aids with professional service, but at genuinely competitive prices.

How long do I have to try the hearing aids before committing to keep them?

We offer a comprehensive 60-day money-back guarantee, which gives you twice the industry standard time to properly assess whether your hearing aids are right for you. This extended period recognises that adjusting to hearing aids takes time, and your brain needs several weeks to adapt to the amplified sounds.

Unlike many providers who offer just 30 days, we believe 60 days gives you the confidence to test your hearing aids in all the situations that matter to you - from quiet conversations at home to busy restaurants and outdoor activities.
