If your hearing loss is long term and congenital/ heriditary in nature, perhaps poor in the low frequencies - and you have worn analogue hearing aids sucessfully before --- then Analogue may be the choice.
Please do not chase the digital Panacea with money. It'll cost you. And you may never rehabilitate. Try the digital aids via the NHS. If they don't help as much as your previous analogue aids - Discuss this matter with your GP, your ENT consultant or contact me on http://www.hearingchecktoday.co.uk/
added 24 4 09: did you know analogue hearing aids are far more expensive to manufacture than digital aids??? This may be part of the reason that they're being removed from sale...

Ear Mould Care
To maintain your hearing aid moulds…
Clean the earmould daily. Wipe it with a soft, dry cloth and always check the opening of the earmould to be sure it is not clogged with earwax. A clogged opening will prevent sound from reaching your ear.
About once per week you should wash the earmould. Remove from the hearing aid, run under lukewarm water, shake off excess water and leave to dry overnight in a warm place.
An alternative method is to use an ULTRASONIC CLEANER. Remove the mould from the hearing aid, half-fill the cleaner chamber with warm water (and, optionally, half a steradent or similar). Close the lid and switch on for 3 minutes. Remove, shake off excess water and leave to dry overnight in a warm place.
Before fixing it back onto the hearing aid, make sure that the mould is completely dry. Preferably, use an EARMOULD PUFFER to blow out any remaining moisture from the tubing.
To reattach the earmould to the hearing instrument: Make sure that the curve of the earmould matches that of the hearing instrument and that the correct mould is fitted to the correct hearing aid. The Red is right, Blue is left.
To prevent moisture build-up in the tubing, remove your hearing aids for a few minutes every four hours or so. Condensation droplets collecting in the tubing are a sign that your ear is perspiring too much. It is advisable to use an Earmould puffer to blow out the tubing regularly.
Consult your hearing care professional if …
• The earmould causes pain or discomfort or is too difficult to insert
• There are sharp or rough edges on your mould
• Earwax cannot be cleared from the earmould
• The tubing becomes yellow or brittle
• The mould becomes yellow / amber or cracked
• The hearing instrument whistles making it impossible to set the correct volume
• The mould seems loose
• The tubing becomes loose
• The tubing is not securely attached to the hearing aid or is too difficult to attach
Earmoulds work better if they fit accurately. Considerable weight loss or gain, facial palsy, certain dental work and the passage of time can make earmould fit less well. It is advisable to consider new moulds every two years or so, in any case.

Things they'd rather you didn't know
In the ear hearing aids break down frequently. The receiver will deteriorate and cause distortion after around 6-12 months.
Hearing aids last about 4 years, on average.
Hearing aid sales are increased when the continuity of service is interrupted. i.e. Companies don’t mind when the original dispenser is replaced. The new dispenser will be more inclined to offer new hearing aids as there is no emotional connection.
The manufacturers operating in the UK market are: Siemens, Starkey, Widex, Oticon, Phonak, GNResound and Puretone. Most other names are subsidiaries of these companies (such as Unitron, part of Phonak: Bernafon, part of Oticon, Hansaton and Rexton, part of Siemens). You should be offered models from ALL manufacturers. If not, why not?
Your hearing and/or cognitive listening skill changes all the time. If you are a hearing aid user, Does your dispenser plug your hearing aids into the computer at every meeting? And when was your hearing last tested?
Avoid dealing with dispensers that do not state up-front prices for specific products. Buying hearing aids can be emotionally challenging and you be in a vulnerable state when you make a commercial decision.

About Me
I have 15 years’ experience in dispensing hearing aids in very high volumes through National Companies’ Exhibitions and Open Days; and in the management and training of commercial hearing aid dispensers.
My conclusion is that the long term one-to-one service that’s needed with this type of product can be more effectively delivered by an independent small business; which is successful in how it cares for it’s clients, but not too commercially motivated that it grows too quickly or too distant from them.
That’s why I now run my own Practice—in Cleckheaton, West Yorkshire and provide Intelligent hearing aids, devices that compliment them and mobility products (such as scooters, rollators and stairlifts).
I believe in good, honest straight-forward advice and in letting my clients understand exactly what they need to do to resolve any hearing or mobility difficulty in their life… I provide traditional levels of service and a commitment to aftercare that is rarely experienced these days.
I’m now able to supply RECHARGEABLE HEARING AID BATTERIES, a product that seemed very difficult to find… Not Anymore!
AND, I’m able to adjust your hearing aids only one week after fitting and again two weeks after that! It’s a method that works and it’s far more likely you’ll end up happy this way!
I hope you feel a little more informed at the end of your visit. That’s my intention.
It appears many of us try to wear hearing aids not really knowing enough about what they’ve bought (or been given) or what to expect.
I’d like to help change any misconceptions or concerns you may have. Have a look through my pages at www.hearingchecktoday.co.uk , and if you’d like to have a chat, just call 0800 6127 812

After sounds leave the cochlea, neural proccessing begins
Electrical impulses travel through the auditory nerve to various positioning processing stations in the brain. The auditory cortex (part of the ‘grey matter’) is where most of the sorting, processing, and filing of information is carried out.
Damage to this area will cause a loss of subtle awareness to sounds but reflexive response will remain.
At the same time, there is also plenty of communication between the right and left temporal lobes so that signals can be compared. The comparisons and analyses made play a role in suppressing background noise and in allowing a person to focus on the sounds he/she wants to hear.
THE PRIMARY (AUDITORY) CORTEX
In the rat, sounds are organised into 2 fields, In the rhesus monkey, sounds are organised into 15 fields (or channels). It is not known how many are available in humans, but it will be higher than 15… It would be useful if we could mimic these fields…
THE SECONDARY CORTEX in combination with other regions, may be involved in the processing of complex social harmonic, melodic and rhythmic patterns.
THE TERTIARY CORTEX seamlessly integrates and combines everything into the overall experience of rich complex sound (music) – linked to pleasure and enjoyment
The right auditory cortex has long been shown to be more sensitive to tonality
(music, tuning an engine, etc), while the left auditory cortex has been shown to
be more sensitive to minute sequential differences in sound, specifically speech.
The Rostromedial prefrontal cortex is tonality sensitive - it is activated by the tones and frequencies of resonant sounds and music. It’s also believed to integrate emotional,
cognitive and visceral information. (The Medial prefrontal cortex) is thought to be the core developmental difference between the naughty child / impulsive teenager and the
calm, mature and reasoned adult. And may aid in the inhibition of negative emotion. It could be hypothesized that this is the mechanism by which music lifts the soul!

“One in Seven”
“35.000 Britons aged between 55 and 74 years took part in the study
carried out by the Medical Research Council for the National Health Service.
12% were found to suffer from moderate to severe hearing loss.
Yet, just 3% used hearing aids.
‘We know that on average people live for 10-15 years with hearing difficulties
before they present to doctor’ said Adrian Davis.
The average age for a first hearing test among Britons is 70 years.
At that point, more than half of them already suffer from significant hearing loss.
Living with untreated hearing loss can make people depressed and withdrawn
and result in social isolation and problems at work.”

tips for NEW HEARING AID USERS
1.Call your home insurance provider. Check that your new hearing system is adequately covered against loss and accidental damage.
2.Check for binaural balance every week using a constant sound source (on each side, listen to a ticking clock or dial tone – it should sound equal. If it doesn’t, call your dispenser straight away).
3.Use a dri-aid kit. A very economical way to protect your system. This slows down moisture ingress onto the receivers. Buy at http://www.hearingchecktoday.co.uk/
4.If you experience acute perspiration in the ear, it is safe to use a hair dryer on your aids once a week, to dry out the receiver. Only attempt this after personal instruction from your Dispenser.
5.If you produce a lot of earwax, consider using a wax-suction tool. Your Dispenser can advise on it’s correct use. Buy at http://www.hearingchecktoday.co.uk/
6.NEVER let problems develop – call your dispenser immediately things don’t seem right. It is so important that problems are dealt with quickly.
7.If you have a chronic wax problem, decide on a regular strategy and stick to it. Over-production of earwax will affect the efficiency of your instruments, but this is normal following a new fitting, as the body tries to reject the ‘foreign body’. Make sure you don’t let your aids get blocked up.
8.It’s a good idea to remove your instruments every 4 hours for a five minute break. Ears get hot and sweaty. The impact on the electronics of this moisture must be minimised.
9.It is quite normal for the amplification to seemingly reduce over time. This just means you’ve got used to that amount of new sound. You need to call your Dispenser who will increase the volume nearer to the full prescription level in stages, allowing you to adapt successfully.
10.Check that your television is set optimally for your hearing, that the speakers are not obscured and that it is functioning correctly. Your hearing aid audiologist can advise on these matters.
11.Check that your telephone is digital (most new ‘phones are), functioning perfectly and suitable for the hard of hearing (it has a volume control, preferably a loudspeaker function and/or a loop compatible with hearing aids). Hold the handset as instructed by your hearing professional. Hearing aid-compatible telephones are available at http://www.hearingchecktoday.co.uk/
12.You will notice you still say ‘pardon?’ and occasionally miss things. This is a habit that has formed over many years and is one that will take time and patience to break. Eventually, your brain will catch up!
13.You will notice it is very noisy outside and in busy places - because it’s all new to you. Your brain will find it near-impossible to work out all the sounds and to place them correctly. This is a skill that is learned gradually. Don’t worry. It’s important to understand that hearing better is a process that takes on average 3-9 months.
14.The adjustments a dispenser can make to sound quality in a modern artificial intelligence system are incredibly precise, so the more specific you can be in describing your experiences over the first few weeks, then the better he/she will be able to help you. Please be patient.
15.Do not tolerate ANY loss of sound quality, at any point – call your Dispenser!
16.Get an audiogram completed every year and keep each one on file.

How to fit and remove IN THE EAR HEARING AIDS
HOW TO INSERT YOUR CUSTOM HEARING AID:
•Look for the coloured serial number mark on the shell.
Red is for Right ear (Blue is left).
•Hold aid with that serial number facing forward, visible to someone looking at you.
•Hold with your thumb on the underside and index finger on top.
•Do not twist your hand or attempt to ‘screw’ the aid into your ear.
•Gently ease the aid into your ear, with the serial number always facing forward.
•Use the tip of your index finger to settle it into position (preferably with
your palm facing forward). You will be able to feel the battery lid and
any buttons/ controls.
•The aid will probably whistle if you touch it or cup your hand over your
ear. The louder the volume, the more likely. This is normal.
HOW TO REMOVE:
Use your thumb only to lever the aid upwards. As it loosens, grab hold
of it. If this is difficult, try pushing your ear up from underneath the
hearing aid – it will pop out.

Elements of sucessful hearing aid use
...READ THIS IF YOU'VE JUST HAD A HEARING TEST, AND PRESCRIBABLE HEARING LOSS HAS BEEN IDENTIFIED
The 1st step is your full REALIZATION of the problem
- a prescribable hearing loss is present ALL the time!
You will need commitment and patience…
It is now confirmed that you have a prescribable hearing loss. It’s very important you take positive action to correct this. Hearing loss usually gets worse over time.
Please note; the ability of your hearing aid audiologist to correctly program your hearing system is critical to the success of the fitting. Incorrect programming can weaken, or even completely invalidate the technology. Skillful and intuitive understanding of your specific needs and listening to your feedback over several visits is a vital component to eventual satisfaction (Think about the difference between being attended to by a dedicated and experienced Nurse or Motor mechanic, and one not so skilled!).
Once fitted, you must wear the instruments as instructed and communicate any programming needs clearly. Unfortunately, hearing aids do not deliver instant results.
SPECIFICATION –You'll need the correct number of channels, the right compression level and processing speed to match your expectations and lifestyle requirements
This is not as complicated as it sounds!
At present, there is widespread consumer misunderstanding about the differences in digital hearing aid technology and performance. It is useful to understand some basic measures of performance.
Speech covers a variety of frequencies - from low pitched loud vowels to high-pitched quiet fricative consonants. Hearing loss usually varies in severity across a range of frequencies. When fitting a loss, the dispenser wants to match the right amount of amplification to the appropriate frequencies. The more channels, the more accurate the matching.
If a hearing loss is relatively flat across the frequency spectrum, is recent and straight-forward in pathology and the user’s lifestyle is very limited then 1 or 2 channels will be sufficient.
Otherwise, multi-channel systems are preferable.
Please also bear in mind that the processing speed of a channel varies considerably from product to product (of current products, the processing speed varies from 1 million bits per second down to 200 bits per second!). Note: There are many single channel aids offered in the market at attractive prices, however they are always technically inferior to the free NHS provision.
Also, Each manufacturer’s product tends to work on a designed principle of compression that gives it it’s own specific sound (or say, taste, like different wines have unique flavours).
Quite often, a client will dislike a make purely on that factor, no matter how expensive the hearing system is. Some hearing aids will always sound ‘too sharp’, ‘too echoey’, too ‘muffled’, ‘not distinct’ etc. So, it’s very important your Dispenser can choose from all products available and that a money back period is provided.
BALANCE - In all cases, BINAURAL BALANCE is crucial. Make sure that is the case!
All new fittings should be double tested for actual balance from side to side.
Subjective differences in sound can occur when hearing aids are not double-checked
at the point of fitting. (If the audiogram and computer are relied on too much, imbalance often results)
After the initial programming is done, a sound should be presented to each ear separately and the wearer asked to confirm the sound is the same. This balance checking is an excellent way to periodically check your own hearing aids.
USEABILITY – Will you be able to operate the aids?
Do you go for manual volume control, a program button, a remote control or ‘Automatic’?
Manual volume controls are tricky to balance on a daily basis. Handling wherever a change in environment occurs is tiring. However, being able to decide on volume level suits some clients. And the recent development of ‘Intelligent Learning volume controls’ is of great interest.
Alternately, an ultrasonic remote control or small push-button on the instrument can be provided. This allows the user to change the listening program, possibly for comparison tests over the first weeks or for specifically challenging environments. This provides greater versatility and for more rigorous testing of any device. It may be rather fatiguing or over-complicated for some users but does offer the greatest level of user-control. Most will prefer the easiest to use Automatic systems and the increased Dispenser contact that these entail.
PRESCRIPTION HABILITATION
Full prescription is rarely acceptable on day 1
The majority of clients will initially prefer a toned-down volume and frequency setting. However, after a short testing period, they will be ready for an increased signal closer to full prescription. Too much, too soon generally leads to rejection. This effective approach greatly increases the likelihood of success and is provided by me over a course of visits.
Understanding the possible consequences of ignoring the problem…
AUDITORY DEPRIVATION v AUDITORY ENHANCEMENT
“Hearing aids stimulate brain activity
A hearing aid does more than help you hear. It also helps your brain remember the sounds you cannot hear without your hearing aid.
Most often, hearing loss sneaks up on you. Suddenly one day, you notice that you no longer hear the humming of the refrigerator or the birds’ singing. On average (in the UK), it takes 10 to 15 years for people with hearing loss to finally do something about it. Many people are simply waiting for the hearing problem to go away. This rarely happens.
Untreated hearing loss affects your quality of life, but it also affects the brain’s ability to remember common everyday sounds because the hearing channels are no longer effectively used. When the hearing nerves lose their function and no longer channel sound signals to the brain, the brain ’forgets’ the sounds over time and becomes unable to understand them.
Memory weakening
The brain centre for hearing stores sounds and noises for up to three years following the onset of a hearing loss. But after about seven years the memory becomes weaker and weaker. Therefore, it is important to have your hearing tested and hearing aids fitted when you find that you are losing some of your hearing. Once you have hearing aids the hearing processing resumes supplying signals to the brain.
Learning to hear again
If the fitting of hearing aids is seriously delayed, however, they will not be able to
transform the incoming sound signals into understandable information. This means that the brain no longer recognizes ordinary everyday sounds and noises, such as the hum of the refrigerator or the computer. The brain must learn to hear all over again.
If you have any doubts about your hearing, you should see your hearing professional and have a hearing test” (Source: Forum Besser Hören, 2002)
Raised Voice
Auditory deprivation can affect your recognition of your own speech sound.
The level of control you have on the amplitude of your voice can be affected by an untreated hearing loss. Those with hearing loss will often raise their voice inappropriately. Often on the ‘phone or in general conversation with family members. This unfortunately will be misread by some, often children, as aggression.
Your conversation style may alter as a result of your hearing loss. It is not unusual for those with hearing loss to talk over others, seemingly intent on finishing what they want to say before allowing an answer. Conversation may become rather stop-start… again possibly being misinterpreted in manner.

Note: There are many single channel aids offered in the market at attractive prices, however they are always technically inferior to the free NHS provision.
Also, Each manufacturer’s product tends to work on a designed principle of compression that gives it it’s own specific sound (or say, taste, like different wines have unique flavours).
Quite often, a client will dislike a make purely on that factor, no matter how expensive the hearing system is. Some hearing aids will always sound ‘too sharp’, ‘too echoey’, too ‘muffled’, ‘not distinct’ etc. So, it’s very important your Dispenser can choose from all products available and that a money back period is provided.
BALANCE - In all cases, BINAURAL BALANCE is crucial. Make sure that is the case!
All new fittings should be double tested for actual balance from side to side.
Subjective differences in sound can occur when hearing aids are not double-checked
at the point of fitting. (If the audiogram and computer are relied on too much, imbalance often results)
After the initial programming is done, a sound should be presented to each ear separately and the wearer asked to confirm the sound is the same. This balance checking is an excellent way to periodically check your own hearing aids.
USEABILITY – Will you be able to operate the aids?
Do you go for manual volume control, a program button, a remote control or ‘Automatic’?
Manual volume controls are tricky to balance on a daily basis. Handling wherever a change in environment occurs is tiring. However, being able to decide on volume level suits some clients. And the recent development of ‘Intelligent Learning volume controls’ is of great interest.
Alternately, an ultrasonic remote control or small push-button on the instrument can be provided. This allows the user to change the listening program, possibly for comparison tests over the first weeks or for specifically challenging environments. This provides greater versatility and for more rigorous testing of any device. It may be rather fatiguing or over-complicated for some users but does offer the greatest level of user-control. Most will prefer the easiest to use Automatic systems and the increased Dispenser contact that these entail.
PRESCRIPTION HABILITATION
Full prescription is rarely acceptable on day 1
The majority of clients will initially prefer a toned-down volume and frequency setting. However, after a short testing period, they will be ready for an increased signal closer to full prescription. Too much, too soon generally leads to rejection. This effective approach greatly increases the likelihood of success and is provided by me over a course of visits.
Understanding the possible consequences of ignoring the problem…
AUDITORY DEPRIVATION v AUDITORY ENHANCEMENT
“Hearing aids stimulate brain activity
A hearing aid does more than help you hear. It also helps your brain remember the sounds you cannot hear without your hearing aid.
Most often, hearing loss sneaks up on you. Suddenly one day, you notice that you no longer hear the humming of the refrigerator or the birds’ singing. On average (in the UK), it takes 10 to 15 years for people with hearing loss to finally do something about it. Many people are simply waiting for the hearing problem to go away. This rarely happens.
Untreated hearing loss affects your quality of life, but it also affects the brain’s ability to remember common everyday sounds because the hearing channels are no longer effectively used. When the hearing nerves lose their function and no longer channel sound signals to the brain, the brain ’forgets’ the sounds over time and becomes unable to understand them.
Memory weakening
The brain centre for hearing stores sounds and noises for up to three years following the onset of a hearing loss. But after about seven years the memory becomes weaker and weaker. Therefore, it is important to have your hearing tested and hearing aids fitted when you find that you are losing some of your hearing. Once you have hearing aids the hearing processing resumes supplying signals to the brain.
Learning to hear again
If the fitting of hearing aids is seriously delayed, however, they will not be able to
transform the incoming sound signals into understandable information. This means that the brain no longer recognizes ordinary everyday sounds and noises, such as the hum of the refrigerator or the computer. The brain must learn to hear all over again.
If you have any doubts about your hearing, you should see your hearing professional and have a hearing test” (Source: Forum Besser Hören, 2002)
Raised Voice
Auditory deprivation can affect your recognition of your own speech sound.
The level of control you have on the amplitude of your voice can be affected by an untreated hearing loss. Those with hearing loss will often raise their voice inappropriately. Often on the ‘phone or in general conversation with family members. This unfortunately will be misread by some, often children, as aggression.
Your conversation style may alter as a result of your hearing loss. It is not unusual for those with hearing loss to talk over others, seemingly intent on finishing what they want to say before allowing an answer. Conversation may become rather stop-start… again possibly being misinterpreted in manner.

The Audiogram explained
A hearing test performed by a hearing healthcare professional (Dispenser) comprises a number of tests which can help to determine whether or not a patient is suffering from hearing loss.
The results from the hearing tests are displayed in the form of an audiogram. The audiogram is a graph which gives a detailed description of your hearing ability and which can be described as a picture of your sense of hearing. Based on the audiogram, among other things, the Dispenser can tell whether or not you are suffering from hearing loss and, if so, determine how serious it is. If you are suffering from hearing loss it is best to have the Dispenser explain the results of the audiogram to you, giving you the best possible understanding of your particular problem.
The audiogram illustrates your hearing ability by showing your hearing threshold at various frequencies. Hearing threshold is an indication of how soft a sound may get before it is inaudible. A hearing threshold of between 0 and 25 dB is considered normal for those aged 60+.The vertical axis of the audiogram represents sound volume or intensity which is measured in decibels (dB). The more one moves down the axis, the louder the sound becomes. This corresponds to turning up the volume on a radio. Zero decibel at the top of the axis represents the softest sound a person is normally able to hear, and is not an indication that you cannot hear any sounds at all.The horizontal axis of the audiogram represents sound frequency or pitch measured in Hertz (Hz). Sound frequency increases gradually the further one moves to the right along the axis.
This movement can be compared to playing on the left side of a piano and gradually moving to the right side where the tone becomes more and more high-pitched. Frequencies between 500 Hz and 3000 Hz are most commonly used during ordinary conversation. During a hearing test the results are recorded on the audiogram by means of red Os for the right ear and blue Xs for the left one. The resulting red and blue lines show your hearing threshold for each ear, and the results may well differ. Generally speaking, the more markings below 25 dB or more, at frequencies which are normally used in conversation, the more difficult it is to hear what is being said. And in situations with a lot of background noise it will often be even more difficult.

Read this before you consider private hearing aids!
some basic buying tips...
· Avoid ‘free gift’ promotions (these are marketing tools to get your name and address)
· Never buy at exhibition-type events: impulse buying of these products is not a good idea
· Never respond to special offers or ‘today only’ prompts, etc
· Avoid adverts that muddy the descriptions of two or more hearing aids on one page… do you really know what offer you are responding to?
· Do not buy £20-or-less amplifiers from adverts. These are sold through loopholes in British law. Please bear in mind that most NHS hearing aids would cost £1500 or more if bought through the private market!
· Avoid non-customised in the ear aids, i.e. where an impression of your ear is not taken. These will generally cause discomfort, at least.
· Always get a FULL money back guarantee for as long a period as possible
· Ask for an immediate refund if there is ANY doubt at all in your Dispenser’s competence or if there is doubt about whether or not you can try a different system
· Do not react emotionally – a logical decision is always best
· If you are not offered a real choice of 3+ technology levels/ price bands, with the specific models named, then walk away
· In West Yorkshire, HSA and Sovereign Health insurance provide financial help towards buying hearing aids
· If a company keeps mailing you, send them a letter asking them to stop!
· Always try to visit a hearing aid practice with a friend or family member and avoid visits to your home. If you do see a hearing aid dispenser at home, never buy on the first meeting and have someone there with you
· If you think you are buying the best possible for your hearing loss, Ask is the hearing aid offered is the ‘latest generation’
· Did you know… Directional microphones are seldom fitted on any ‘completely in canal’ aids
· Unfortunately, big companies have high staff turnover. Ask how long your Dispenser has worked for their employer
· Ask how far away your Dispenser lives from you
· Ask for RECENT personal recommendations from your Dispenser
· Do not ignore a hearing loss OR turn it in to a commercial-only decision...
In short, deal with the problem PROPERLY and EFFICIENTLY. A problem ignored will not go away…

some basic tips on buying hearing aids
TECHNOLOGY EXPLAINED
Don’t let yourself be bamboozled by science and technology; or buy blindly. If you needed to wear hearing aids, wouldn’t you want to know exactly what to look for before you even started?
At ‘hearing check today’, we will instruct you on the few simple measures you can use to determine how good a particular hearing aid is and what you should expect to pay. It’s not complicated and you can become an expert consumer in a few minutes!
ARE YOU READY?
You could waste time and money on buying private hearing aids – or on waiting too long for NHS hearing aids. Why? You may not be ready to accept wearing them. They are notoriously difficult to get used to.
Unfortunately, many new users give up too quickly. It’s so important to know whether or not you are motivated enough to succeed. We can help… again; a little of you time is all that’s needed…
BE A SMART CONSUMER
Do you want to know how to get a truly objective recommendation based solely on what’s best for YOU?
Just as in any other field, your choice of product may be limited by the particular retailer and the recommendation given may be biased, not necessarily in your completely best interests.
Learn about the full choice and an objective ‘whole of market’ opinion!
KNOW MORE
Wouldn’t you like to know exactly how your hearing loss is clinically described and quantified? And by how much your hearing has changed? Wouldn’t it be useful to have your own Audiogram at hand? AND also the other measurement factors particular to you that are used to prescribe your hearing aids?
We will provide you with a diagnostic audiogram to ‘British Society of Audiology’ standards and highlight the significant deciding factors that would definitely be used to prescribe your hearing aids.
UNDERSTAND WHAT YOU ARE BUYING
Did you know that HM Revenue and Customs accept that around two-thirds of the cost of hearing aids is for the professional services provided (or yet to be provided)? These services do not, at present attract VAT.
Hearing aid results are rarely predictable and most instruments are designed to be reprogrammed a few times in the first 3 months — so you need to feel comfortable enough with the original Dispenser to see him/ her repeatedly over the entire period of use. Remember— your hearing aids will also need to be recalibrated at least yearly to keep up with your changing prescription.
