There are all kinds of BTE and ITE aids for sale on Aliexpress, from about US$5 and up.

 

I'm pretty sure that the expensive aids from an audiologist will have programmable frequency equalisation but also the aids are very high tech with DSP to suppress background noise and make speech more clear, some have different switchable programmed modes, one for say listening to music, another for hearing speech in crowds etc etc. 

 

This is all very jolly, but for example some aids that my FIL had - at a cost of about $8,000 / pair - a non tech-savvy retired farmer in his late 70s then - had not the faintest practical clue how to use the modes the audiologist had set up, he had difficulty changing the batteries (and the tiny batteries needed to be changed very frequently) with his fat fingers, the aids had a tiny orifice that would block up with an invisible to him blob of earwax, and if he dropped them they were hard to see and not resistant to being stomped on when he was dancing around in hobnail boots waving his arms in the air saying that he'd dropped a $4,000 hearing aid on the floor.  Couldn't hear the crunch.

 

To cap it off - the DSP modes that had been set up used frequency shift - presumably to adjust voice frequency in to the range where his hearing was best.  This produced truly remarkable effects when he was playing his ukulele and trying to sing in tune, he'd hear himself singing through conductive hearing, the ukulele sound frequency shifted through the aids, it possibly sounded spot on to him - but to anybody else within range it was a horrific discordant cacophony.  The audiologist may have set up a "music" mode which turns DSP off - but he had no idea how to switch modes.

 

Those aids are gone - he's got normal and relatively inexpensive BTE aids - which are much better for his needs.

@eracode:....

 

Would welcome informed comment and advice. Thanks.

 

 

1. hearing loss is a risk factor for dementia. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5527366/

 

2. audiologist are medical provider - therefore this notion of 'selling' stuff for no reason is absurd.

 

3. the cost of hearing aid - you pay what you get. the newest one does not require you to change battery - some has wireless/touch charging

 

4. the reason why they cost so much it is because it is a medical device, personalized to each patient. you can get from aliexpress, but they are almost as useless or even worse than not having anything.

 

5. government does fund up to certain amount (i think $2k - every few years). if it has to do with work related, ACC will fund it rather than govt. https://www.health.govt.nz/publication/guide-getting-hearing-aids-hearing-aid-funding-scheme

 

 

 

good luck

im not sure what the complaints over batteries are, i pay $5 for a months supply of 6 batteries as each battery lasts 6 days and you do get a warning when they are about to run out which gives you 10 or so minutes to replace the battery. You cant go cheap on the batteries as you do get what you pay for . I have tried the Aliexpress type ones but they only last a day or so so you dont save money.





Common sense is not as common as you think.

You've misquoted the title of that paper - that is not what the study claims.

 

It is:  Hearing loss as a risk factor for dementia: A systematic review

 

From the conclusion:

 

Although cross‐sectional studies provide valuable insight into the correlation of hearing loss and dementia, they cannot provide causality, making it difficult to observe the etiology behind the connection. More prospective studies should be done on this subject in order to identify causation rather than just correlation.

 

There's only one (of the 17 studies cited) that suggests hearing aids may attenuate cognitive decline.  I can think of one obvious confounding factor to that - bias in self-selection of hearing aids by the study group.  People with early stage dementia tend to get stubborn - in fact those personality changes usually appear long before any formal diagnosis of dementia. (typically reported retrospectively by family etc - along the lines of "we knew something wasn't quite right for years - never thought it was dementia")

Thanks for your reply. Sorry to say I find it a bit hard to accept your view that audiologists are not there to promote sales of hearing aids. Some audiologists are employed in the public health system but others are businesses that exist to make a profit - which is probably why some of the big chains advertise quite heavily. I don't see them as being any different to Specsavers.

Well, this thread has been the impetuous for me to push my mother to go for a proper test and hopefully determine what aids are suitable (not if she needs them!). In my mother’s case we are also talking early-mid stages of dementia, so there’s that other complexity to deal with (that includes denial of anything that may be seen as related to aging!).

Valuable points made earlier, re the latest and greatest and tiniest hearing aid may not be suitable for some people, and given my mother’s state this could be a key consideration in this case. One likely option, though, is she’ll concede to buying the aids and then just refuse to wear them - just like her personal alarm!

I’ve also elected to book her in with a local, independently owned audiology company and pay for the tests, as I too remain sceptical of the methods employed by some of the firms out there. Also helped to sell it to her that the audiologist is the son of a close friend of my mother’s!

Thanks for the useful information.

that is disingenous. you quote discussion not conclusion part. systematic review means they are looking at MULTIPLE studies related to the subject.

 

boy - the conclusion is this:-

 

While each of the studies included in this study utilized slightly different methods for evaluating participants, each of them demonstrated that hearing loss is associated with higher incidence of dementia in older adults.

It's not disingenuous - it was a mistake in a copy paste - that was from discussion - it was close to the final conclusion (below) and I grabbed the wrong text.

 

My points were that the mistake you made in the title is suggestive that there is a known causative link.

 

The conclusion you quote above shows a correlation.

 

The final conclusion states:

 

 

Multiple epidemiological studies have shown that hearing loss is an independent risk factor for the development of dementia. Future studies controlling for potentially confounding variables and mechanistic studies will be necessary to further elucidate this association.​

 

And it's still a stretch from there to "prove" that hearing aids reduce (progression of) dementia.

I recall no too long ago that you can approach the aged concern orgaisation for impartial hearing tests.

 

It was an article in a recent Consumer mag about hearing aids, and did mention about the so called free hearing tests are not really free, and that the hearing aid market in NZ is controlled by 2 multinational companies.

 

I'll have to check my email when I get home, as I emailed myself the info ...

audiologists are bounded by Health & Disability Act, work closely with ORL & GP - if you truly think they are trying to sell something that is not needed, file a complaint at HDC.

the truth is, most people don't like spending money for their health because they just don't see or understand the long term benefits.

I guess you miss this sentence?

"Multiple epidemiological studies have shown that hearing loss is an independent risk factor for the development of dementia."

What you highlighted is merely a recommendation of the author(s) reviewing the papers....

No I didn't miss that - nor the comment that more research is needed to validate the suggestion that more research is needed (allowing for potentially compounding variables) - and then there would be further studies needed to find out if hearing aids could be useful to ward off dementia.

 

Lots of things might be useful to ward off dementia.  It kind of doesn't matter with hearing aids - as if you need them you need them to ward off all kinds of other issues anyway.

 

I really do think that something needs to be done about the price of hearing aids - they are way way too expensive for many people, that's a huge barrier if you don't qualify for ACC.

Just to round-off my OP: The family member concerned has determined that she doesn’t need aids at this stage and has returned them to the probably profit-seeking audiology chain half-way through the two-week ‘free trial’.

If/when necessary later, she will take the excellent approach suggested above by @SepticSceptic.

Appreciate the replies.
