Last Hearing Aid UK Update: 15
Noticing a change in your hearing can be unsettling, and it is not always easy to know whether it is something that will pass or something more lasting. The answer usually depends on the cause. This article explains the difference between temporary and permanent hearing loss, and helps you understand when it is worth seeking help quickly.
If you think you might have developed sudden hearing loss in one or both ears, you must speak to your GP as soon as possible, ideally the same day. Sudden sensorineural hearing loss (SSNHL) is a recognised medical emergency.
According to NICE guidelines, sudden hearing loss that has developed within the past 30 days requires immediate referral for specialist assessment within 24 hours.
Treatment with corticosteroids is most effective when started quickly. This is a prescription medication given by your GP or an ENT specialist, not something to source independently.
Research from University College London Hospital, the largest study of its kind to date, found that patients who received steroids within seven days of onset were five times more likely to fully recover their hearing compared to those who were not treated in time. Without timely treatment, what begins as sudden hearing loss can become permanent.
If your sudden hearing loss has come on without any obvious explanation, such as a recent illness, stressful period, intense exercise, or exposure to loud noise, sudden sensorineural hearing loss is more likely to be the cause. In that case, getting seen urgently is even more important, not less.
Usually, temporary hearing loss is gradual and becomes more noticeable after a few days or weeks. It may also be due to a blockage in your ear canal or another similar underlying health condition. Common causes can be:
A common cold can often develop into an ear infection, which is known to affect hearing. While it is more common in children, it does happen at any age. Ear infections usually clear up on their own, but it is advised that you see your GP to be examined, in case you need to be treated with antibiotics.
The tiny hairs and glands in your outer ear canal naturally produce cerumen, which is more commonly known as earwax. Even though this wax falls out on its own, it can build up over time, blocking your ear canal. This blockage might make you feel like your ear is "plugged"; you might even experience ringing (tinnitus), or your hearing ability might be affected.
If the wax does not shift on its own, do not be tempted to use cotton swabs or anything else to dig it out. You risk pushing the wax deeper and potentially damaging your eardrum.
A few days of over-the-counter ear drops to soften the wax is a sensible first step, and the NHS recommends this before seeking professional removal. If that does not clear it, your GP can refer you for safe, medical earwax removal.
While cotton swabs are a common cause of ear injury, it's worth knowing that the most frequent cause of a perforated eardrum is actually a middle ear infection, where pressure builds up behind the eardrum until it ruptures.
According to the NHS, other causes include a blow to the ear, a sudden change in pressure, or poking an object into the ear canal. Most perforated eardrums heal on their own within a few weeks, but you should see your GP if you suspect one, particularly if you notice sudden pain, discharge, or a significant drop in hearing.
You can also temporarily lose your hearing or develop tinnitus if you are exposed to loud levels of noise, like live concerts and using noisy gardening equipment. This is commonly called noise-induced hearing loss, which usually resolves after rest, but repeated exposure causes cumulative damage to the hair cells in the inner ear that cannot be reversed.
To prevent this from happening, look into earplugs to protect yourself from the noise. If you continue to expose yourself, you are at risk of more permanent damage.
High levels of stress or intense physical exertion can cause temporary hearing loss or tinnitus. The likely reason is reduced blood flow to the cochlea, the fluid-filled structure in the inner ear responsible for converting sound into signals your brain can process.
When blood flow to the cochlea is reduced, even briefly, your hearing can be affected. This usually resolves with rest, but if it does not clear within a few hours, or if it keeps happening, it is worth speaking to your GP. Recurrent episodes should always be investigated.
There are various known health conditions that can cause permanent hearing loss, such as Meniere's disease, chronic viral infections, head trauma, autoimmune diseases, and genetic disorders. There are also medications that can cause this type of hearing loss, which you can read more about here.
While a short exposure, or even a single sharp blast, may cause temporary hearing loss, a repeat of this over long periods of time can lead to permanent hearing loss. This is one of the main causes of sensorineural hearing loss, which is unfortunately permanent. Meaning your ear's nerves, along with the small sensory cells, are damaged.
The other main type of sensorineural hearing loss is age-related, also known as presbycusis. This is a gradual decline in hearing, and very important to treat and support with hearing aids - not just to simply hear better but to assist in brain health and reduce the risk of dementia.
Whether you think you have temporary or permanent hearing loss, it is important that you speak to your GP, who will assess you, determine if hearing loss is present, what type you have, the severity, and advise on the best treatment for you and your hearing health.
If you have already spoken to your GP and been told your hearing loss is permanent, the next step is a full hearing assessment with a qualified audiologist. Book a free hearing test at a clinic near you or in your own home, with no obligation to buy.

Hearing aid stigma Do not spend hundreds of pounds without getting a second opinion from us.
Not only are the prices great, but the service is fantastic! Many thanks to your team.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.
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.

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.
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 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.
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. Find out more about our warranty cover here
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 an HCPC-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.
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.
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.
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.
