This can be adjusted to your preference.
Hm, ‘quick’ means a bunch of seconds (I didn’t measure, but think more like 5, not in an instant), I’m not sure that customers will want to wait or understand that they have to wait.
It depends what’s your QuickSIN score, or similar - how much signal to noise ratio you need.
Aids are limited to give a bost of around 9db in ideal conditions, and mics go up to 15.
And low tier aids usually are restricted in how much help they give (in order to have reason to sell the top tier models)
Select definitely catches better, on greater distance than pen.
But leaving select on some desk, I mean, it’s expensive piece of equipment and without a way to chain it down so that it could not be taken away. I wouldn’t dare to use it in such environments.
Definitely find a practice which does proper testing.
Tonal audiogram is useless after a point ‘yeah, you do have frequency loss’.
You then have speech audiogram, which tests how well your brain works with loud and clear inputs. I assume that results would be fine in your case. It can be used also in combination with white noise in te background to see how that goes.
And then you have SNR/SIN tests which clearly measure how well you cope in background noise, when that noise is of complex type, speech babble.
Find a practice that is able to give you all those 4 tests. Then they’ll be able to give you proper advice based on those results.
From a distance, I’d guess, if your SNR isn’t THAT bad, you might get with mid/top tier aids alone, to use them as a noise filtering device, and not as a hearing aid.
Like, phonak marvel/paradise 90 have this stereozoom where two aids work together to focus on sounds in front of you (automatically in model 90, and as a custom program in model 70), when the noise is above given threshold. But for such environment, unchained mics doesn’t seem like a good idea.
Lower marvel/paradise, so 30 and 50 don’t have that stereozoom feature.
Also, if you’re in USA or UK, go to costco and try KS9, that’s basically marvel 90, for price of 1500 usd for a pair.
Select or pen + 2 roger focuses would probably cost more.
But, choosing the device should come AFTER proper testing. Good fitter who knows that all of those tests are useful and for what is worth their price in gold.
And you need someone who really gets it.
Not someone who will tell you that you can’t have a problem because tonal audiogram looks fine, or who isn’t able to tell you your SNR values, because how they can tell you what could help you, if anything?
Yeah, my strongest advice would be to find a new job, but maybe you got ‘lucky’ and your SNR isn’t that bad and some aids can help it. I ain’t lucky, and even mics cannot really help me (but are better than without them).
Since I can’t see how mics could be used in such environment to keep you responsive and keep the device safe.
Also, just wearing aids with not open domes, ideally powerdomes if you can cope with them (or just vented ones), can really help, since you utilize aids for noise removal and you have passive noise cancelling from the fact that your ear canal is closed by the dome.
MAYBE those apple earbuds could help in a same way in their transparency mode?
I’d look into that as well.
There were some other headphones, I think bose hearphones or something called like that? Check through topics in #assistive-listening-devices there might be some useful info for you.
