Trying to learn about hearing aids and "gain"

Nope your not making much sense I’m afraid, it seems your looking at this wrong,your HAs are fit by your audiologist to your audiogram, the software will determine the appropriate level of gain, hearing aids cannot restore your hearing, they are an aid to help your hear, looking at your audiogram show’s a severe to profound loss in those higher frequencies, you’d be a ideal candidate for frequency compression, ideally work with your audiologist.
You could also check out the manufacturer’s software, this would give you a much better understanding of how things work, what HAs are you using at the moment?

Do some reading in the DIY forum.
Lots to learn.

Fitting hearing aids is challenging.

We have some members who are flat smart about it and others who are not. You have to figure that out.

Good luck

Yes I believe it is similar to Quattro. I asked on a previous topic for more info on the hearing aid brand I am wearing and got helpful responses. I know I mentioned already next week I am seeing an audiologist for an hearing aid upgrade according to the letter I got so fingers crossed. Ambio 77 I have is BTE with earhook. I did have power domes but changed to earmoulds which is much, much better and more comfortable… I would not dare do any DIY on any hearing aids, I have no clue haha.

@Zebras is very knowledgeable about NHS aids, and many other things. She may be able to help.

So if somebody has a severe hearing loss, are hearing aids able to bring it back up to normal to mild on the audiogram?

You only get a 1/3 of the gain needed for your loss, so 20 dB gain for a 60 dB loss.

Otherwise it’ll be super painful.

It’s literally searchable on this site:

If someone has 70db HL and gets 70db HA gain, does he hear 0db?

From a previous thread: OK, it comes down to the application of gain. First you have to understand that these numbers we throw around on here 80-90-100 dB aren’t a linear scale. To put it simply, if one speaker puts out 80dB and you put another speaker right next to it you produce a whopping 83dB. So a doubling of ‘power’ equates to a 3dB rise in measured output. The next thing to take into the equation is that there’s a reasonability test applied to gain which forms the basis of all gain cal…

Thank you will read through.

Unfortunately, especially with search algorithms guessing, many times you need to know what search terms give the desired information.

Let us know on here what it comes out at. It is interesting, for me any way!

What Zebras says was true back when linear hearing aids (which will give the same amount of gain to almost any input) were used, nowadays almost all hearing aids use compression so that no longer applies in general.

Hearing aids give maximum gain (basically as much as dictated by your audiogram at a given frequency) to barely audible sounds (for a normal hearing person) so you can also barely hear them, less gain to medium volume sound, and no gain to high volume sounds.

Watch this couple of videos to get a more detailed explanation:

@maac

The most powerful Ultra Power Hearing Aid is either max of 84 dB or 86 dB so how can that fit a 110 dB loss? (If they would offer 110 dB worth of gain?)

What I said, was only said to me around 15 months ago.

and no gain to high volume sounds.

But someone will need to hear high volume sounds if their hearing loss is severe enough?
