dad has them, refuses to use them.
when ive asked him or suggested it, he walks of and sulks...

Help me understand.
The technology is there, yet a lot seem to have a pathological fear of it..
Hello,
If Dad was not so deaf you would not be so blind!
How do I do this, it is a complex mix of topics.
First hearing aids do not cure anything, to many they are a huge disappointment. If you with your intact hearing go to a holiday party you hear many things and you can focus on any one of many conversations within ear shot. Hearing aids just make things louder like the rumble of the refrigerator compressor in the kitchen and you cannot make intelligence of any of the conversations.
Now add the psychology of an old cranky fart. You are old depressed and you cannot hear.
It is not about the technology.

I guess if you use a hearing aid it's an admission that you're going deaf. Other people can see you wearing it, so they know you've got a problem. In days gone by deaf people sometimes got treated with a lot of prejudice. Put these things together and I can see why someone might shy away from wearing a hearing aid, illogical as it may be in terms of getting to hear better.

I remember getting a certain amount of stick about wearing glasses. Once I got contact lenses I wouldn't go out in glasses. It wasn't vanity. I used to get in a lot more fights previous to that. I believe that was because a certain kind of person looks at somebody wearing spectacles and sees a victim.

I guess it might require the utmost in tact and understanding and patience to be able help some people.

What ?!?!?! Hearing aids don't cure cancer ?!?!?!?
No one ever told me that.. *rollseyes with much sarcasm* Insert big cheesy grin here ....

HOW are they a disappointment ?
Are those that need/use them expecting to be able to hear like an 18 year old again ?
Even I know thats not going to happen.
Aids, are called aids for a reason.
I wear glasses, they are an aid, I certainly don't expect them to 'cure' my failing eyesight.

Ok, so they amplify the weak frequencies, i understand that.
your argument about focusing on one area of whats being heard.
Don't 'normal' people hear all sounds etc at a *uniform level ?
*(not going into full psychoacoustic properties here)

If so, then aren't the 'normals' just using the brains ability to 'filter' what they want to hear anyway ?
So, hearing aids or not, shouldn't it just be a matter of being able to concentrate on what is important to you at that time ?

Isn't using headphones, or turning the volume up on a tv/radio/etc, doing basically a similar thing as using an amplified 'personal' speaker (hearing aid) ?

To recap, I'm not hard of hearing, and as such, I don't understand the reluctance of people to use whats available.

Old'n'Cranky, me too
Hello,
I am not trying to pick on you nor am I making this stuff up.
You cannot fix it and it is not about the technology. Look up the Kübler-Ross model for the 5 stages of grief. Denial and Anger are good start.
BTW it is not just paying attention and will power that lets you sort out the intelligence in sound. The refrigerator and chairs sliding on the floor drown out the conversation, really, hearing aids and all.
Hearing aids can help in a quiet one on one conversation with minimal interference. Look Dad in the eye when you talk with him.
You did say “help me to understand”.

I do realise your not "picking on me".

think of me as someone thats never seen or heard of a car, and you have to explain what it is and why its needed...

i understand about the grief etc cycle.

its just the logical side of me that has issues understanding the finer (real ?) details of this issue in particular..
For what its worth, and closer to the op.

dad also has a s'sung tv (6 series led)
has hphone, optical, hdmi outputs, using the hphone socket does disable the built in speakers.
it has a graphic eq built in, but sadly it only works on the built in speakers...
so i've come to the conclusion the only way i can help him is to use the hphone output, through an old car equalizer then to his 'phones...

Hello,
Speaking of technology and hearing loss. Louder may not be better. Hearing loss varies with the individual. Also hearing loss is not linear across the frequency bands. It is possible that the high frequencies even in the 300 to 3000 Hz (voice) range are so far gone that no amount of amplification/equalization will help.
Some hearing aids use digital signal processing technology and the higher voice range tones are converted to lower frequencies where they are audible to the impaired ear-brain. This is both good and bad. You can hear stuff you could not hear before including the chair dragging across the floor.
Perhaps we audiophiles can take some of that DSP technology put it in a box connect it to the optical/HDMI outputs at the TV. It is hardly the basic high frequency equalization Tom Edison used for his hearing loss or the cut / boost equalization we think of.
If I have sold you I also have a used dodge pickup to sell.

Her hearing loss came on pretty suddenly. She's 76. Seems like in the course of about three months last year it went from excellent to having to ask everyone to repeat what was said... louder. That suddenness can be a factor in a few ways. Made her testier about it and that irritation was reciprocated, unfortunately, too often. And the suddenness so suggested something temporary, wax buildup, infection, etc, that she spent a lot of effort trying to 'cure' it... but to no avail.

She too insists that she doesn't need/want a hearing aid. It's frustrating. She openly appreciates the "aid" I've set up on the television. But she'd prefer to have it seen as a temporary thing.

My great aunt finally reliquished her driver's license this summer. 93yrs old. About five years too late as far as all around her were concerned. It was a wonder that she never killed or was killed in that time. She didn't even seem to like driving, and we'd chauffeur her anywhere, anytime she needed like a queen. But she so identified losing the privilege as a marker of decline that she fought it like an illness. Mom probably sees the hearing aid similarly.

Guess I won't really know how it feels till I get there. I'm on my way. I was pretty unkind to my eardrums through the years and tinnitus is a part of life now.

Sorry I've gotten so off topic in this part of the board. But thanks again for the input, kind advice, and sharing stories.

I built my dad a headphone amp for a similar problem.

The essentials though were based on an idea in Electronics and Wireless World many years ago. It uses a tuned circuit, a coil and cap and resistor to generate a massively peaked response, something that a simple opamp/equaliser can not do.

I'll try and dig out that part of the circuit if your interested. The rest I made "on the fly" so haven't got a circuit diagram. It detects audio on the phone lead inputs and power up by means of an optically isolated Triac to switch the mains supply. The detection part is ultra low power design with a nicad cell to power it.

The peaked response is the vital bit... right where it's needed at around 2khz although component choice can alter this if needed.

Thank you mooly

I'll give the graphic EQ a try first since it's straightforward enough. I may pm you at some point in the future if I decide to give that a try.

I'd like to see that circuit if you can find it.
Thanks Mooly..
