I noticed just few points on EQ (6 or so?). Having better granularity throughout the whole spectrum I think would help to all variety of hearing losses.
HAs most commonly focus on 1-2k and then they toot their horn about how much up they go, but it’s in big steps after 2k up to cca 8-9kHz and then cut. Starting at around 150Hz.
So far I’ve seen only max 20 adjustment points but with a big caveat - you cannot really change them, because they’re all connected to so called prescription formulas, be it from manufacturer, or NAL-NL2 or or DSL 5 as most commonly used ones.
Btw compensation for our loss isn’t reverse of the audiogram, but prescription that’s given by those formulas (they take into account various things, including audiogram).
However, all these formulas are focused on people wth high frequency hearing loss.
Regular headphones with more gain work for people with more horizontally looking loss. That’s why you’re going to hear them saying how regular headphones work fine for them, better than HAs for music, because they have bigger speaker and are made for music, after all.
However, there’s zero things for cookie bite losses and reverse slope losses and any other exotic ones, since they’re rare. We don’t even have formula, and are considered really hard to fit.
Rare means that there’s some numbers about ‘one in several thousand’. Or ‘I saw this 6 times in my life as a fitter’. Or from currently active members here I’m the only active one here with RSHL and I think I saw one cookie bite.
But even if they/we are rare, since no one is thinking about us, having gadget we could adjust to our loss, and I mean really adjust, would be a game changer.
So, give 200Hz steps or so from 400Hz up to 5-6k (speech is I think 1-4k, I guess singing goes higher, check), and cover from 20Hz to 16kHz (lower end 50hz steps, higher maybe 400-500), and add portable microphone and you’ll have better HA than bunch on the market
Music is definitely more dynamic than ordinary speech, and they differ a lot between genres.
No HA works with that afaik.
Of course, you could have normal (with 6 handles) and advanced (with all of them) view for EQ.
Only reason why I didn’t bought your gadget as a solution I was looking for as a person with unilateral hearing loss is because expected release is mid next year, and I want/need to hear now, and I’m buying two HAs instead of one because I couldn’t find other (convenient) solution. Plus they should work better together, but that I didn’t manage to test throughly yet.
And I saw that people say that tcoil sound quality is inferior to BT (not because of buzz but also in ideal conditions).
However, if you think about offering BT (one ear) + wire option (second ear), think about latency. It’s horrible
There’s a ‘solution’ of roger select iN for marvels plugged in a mic+audio splitter and additional mic works the best. Buy you need bunch of wires, very specific HA and roger tech is proprietary. It can be modded with custom made splitter (since there’s available on the market) to work for unilateral loss, but your gadget is definitely more elegant solution that works for wide range of HAs.
I really like the idea!
So, I’d say, focus on improving tcoil as much as is possible. BT on both ears should be ok. But warn people with unilateral loss what to expect, so that they don’t get angry
Plus, think about longer battery life or making option with swappable battery (just give us doors, battery pack and charger would be insanely better solution to bunch of others with built in batteries). 6h isn’t a lot for someone working on video conference calls for example. And if they want to play music after work, no juice anymore. And let’s not forget, those 6h won’t be 6h after a few years of usage. HAs are made to last 4-6 years, with good care even longer. Most of people don’t change HAs like many people change phones - every 1-3 year (ok, people here mostly don’t change phone on yearly base either).
And let’s not forget, if you have to pay for them yourself, it’s several thousand dollars.
So I think we here are thinking about longevity much more than regular gadget lovers.
I guess also buying two-three and make them work with the same app wasn’t planned by design. I see people often go buying several battery-based things (like microphones) if they need to cover longer periods of time. But it’s built in HA apps or HA themselves that we can use several mics.
This is from top of my head, based on reading or experiencing frustrations with the current technologies.
Hope it helps somehow.
But definitely, start reading whole forum. People won’t notice this thread and come to report, you need to find them.
