It also applied the same profile to both ears, which matters for some. My hearing loss is highly asymmetric.

Does it still do that? I understand it had problems with asymetric hearing loss earlier.

Still did it on 18.0. It just averaged the two ears into a single profile.

I still mourn the long scale. A billion is obviously a million millions.

It is less intuitive for me as an outsider that a trillion would be a million million millions instead of a billion billions

Maybe, but either way is relatively quickly to learn by rote for the few orders of magnitude that come up in 'daily life'.

For anything bigger, you'd use 'scientific' notation anyway.

Whatever the theoretical analysis tells you, I've been able to reproduce a microwave interfering with a wifi signal with at least one microwave and router. I've had other times where it didn't have a noticeable effect though.

Fun story: I’ve had a speaker which would connect to a Bluetooth device as soon as it was turned on, and only enter pairing mode if a paired device wasn’t in range. I couldn’t figure out what device it was connecting to, so I put it in the microwave (while it was off!) briefly to trigger the pairing timeout.

You can make an argument for that, but neither system does that so it's not very relevant to the choice.

I think an exponential system would do better to have a different naming scheme.

It's all too early to tell, but we'll know after a week or so. The battery life thing is not seeming like a big problem, since the existing device needs batteries changed every few days or charged every night. As for the sound quality, a few of our grandparents have tried it, and while they say it sounds 'different', it's not necessarily bad. Grandma was actually quite content even with just the old EQ settings that…

The hearing test on one of the images shows a ‘profound loss’. Does the hearing aid feature work for such a significant loss, or does it disable for any result beyond moderate loss?

The feature only works when hearing loss is mild (26–40 dBHL) or moderate (41–60 dBHL). We had to repeat the test a few times to get it in the range and enable it.

Thanks. Any tips on how to do this while keeping the hearing profile as close to reality as possible?

Thanks! In germany we use the long scale, and this is the first time it clicks. "Eine Billion" is Million² bi -> 2 "Eine Billiarde" is 1000 * Million² "Eine Trillion" is million³ tri -> 3 "Eine Trilliarde" is 1000 * Million³ And so on Yes I knew what a million, milliard, billion, billiarde and so on are, but it never made click that the long scale makes so much sense.

I feel like at that point, I would rather just use scientific notation (10^x). I also like the easy suffix for thousand (k), million (M), billion (B), trillion (T), quadrillion (Q) for written conversation. $10B revenue, 5k liters, 300M people, etc.

Your 'suffixes' are a hodge-podge. Might as well stick with SI prefixes (like you are doing with the 'k' already?)

Hey! I'm Rithwik, one of the authors of the article, happy to answer questions etc!

Thank you for your work. In the substack write-up, you said: "There was more work to be done: we needed a reliable reproduction, and a concrete process." Could you elaborate on the process for unlocking?

It isn’t consistent, but a lot more people can fluently read “B” for billion rather than “G” giga and understand 10^9. The SI prefix “k” is sufficiently used that it is understood.
