Hearing aids that don’t auto connect to whatever my neighbors are playing on Bluetooth. Also hearing aids with a Bluetooth block list
Seriously I’m fucking losing my mind over this. 3 times in under 10 minutes last night my hearing aids stopped playing the tv I was listening to to play the Bluetooth that my neighbors or their kids were listening to. Suddenly mid conversation with my wife about it, bam, music.
If you live in the US that sounds like something the FDA should be notified about. It's probably not legal to sell a hearing aid that can so easily be hijacked by another party, or if it is, it really shouldn't be. Either way, FDA regulates hearing aids so they are the ones to complain to.
The problem is inherent to Bluetooth, The only way to make it not be like this would be to make things dramatically more difficult to connect to things over Bluetooth.
??
I'm no expert on the technical side of the protocol, but my BT devices only ever connect to sources they've been paired with.
Why would this be more difficult for hearing aids than for headphones?
Not at all, those ones are permanently in pairing mode with no interaction required and instead it should require manual pairing
That's horrible!
Do you have a tv connector for your hearing aides to connect to or is it connecting straight to the television?
Work in retirement home where lots of people use hearing aides with their televisions. Have not come across this issue.
Most connect via an external device paired to their hearing aide specifically.
I have a tv beam device
You don't mean the "As Seen on TV" device do you?
No, my audiologist gave it to me. And it’s not like my neighbors are using one. It switches to Bluetooth streaming for their stuff according to my hearing aid app
It's just weird that it switches to someone's Bluetooth. Usually there is some sort of combination of basic authentication required and confirmation. Have you tried something like a "factory reset" on the device?
Yes. I would expect the Bluetooth receiving device to have to be paired with the transmitter
As someone who works in live entertainment, Bluetooth is the bane of my existence. Every single show, I get multiple people asking if they can connect their hearing aids to my system via Bluetooth. The issue is that this question comes from a fundamental misunderstanding of how Bluetooth works.
Hearing Assist Systems have a variety of methods. All have their benefits and drawbacks. But notably, the requirement for HAS is that they provide an identical experience to the user as someone who isn’t hard of hearing. And that’s one of the big drawbacks of Bluetooth. Bluetooth introduces lag. HAS typically works either via radio, infrared light, EM loop, or wifi. And only the first three are acceptable for live events, while wifi is more popular for gyms.
The first three HAS all send an audio signal to the user without lag. Radio is a good example because most people understand how they work. The venue has a low power radio broadcaster (because FCC limits how powerful your radio broadcasts can be without an extremely expensive license) in the room, then each user can dial a receiver to that specific band. Then they’re able to plug headphones or a neck loop into the receiver. And boom, you have a distributed HAS with very little effort. Infrared does the same basic thing, with a light transponder instead of a radio antenna. The receivers watch for that light, and send the signal to the headphones. Lastly, EM coil. Many hearing aids have the ability to listen for EM broadcasts. The venue can install a loop around the room, which acts as a giant electromagnet. The hearing aid user switches to that EM mode, and they can pick up that magnetic signal. This is particularly popular in schools, where radio would have a lot of interference from rooms being so close together; The hearing aid user only hears the signal when they’re inside of the loop.
But all three of these have one thing in common: They have zero latency. The hardware to take an analog audio signal, convert it to radio/infrared/EM, and broadcast it, is faster than the time it takes for the audio signal to move from a singer’s mouth to the microphone. It’s nearly instant, because it’s all analog. There is no digitization that needs to take place; Ir’s just converting one type of energy (electrical energy from the audio signal) into other types of energy. And that is easy and cheap to do.
WiFi is popular for gyms, because it introduces a delay in the audio signal. WiFi requires packets, which requires a digital conversion. And that packetization takes time. It’s a processor calculating 1’s and 0’s. But it’s acceptable for gyms, where you’re only listening to a TV mounted on the wall. They can delay the video signal by the same amount, and you’re golden. Now the delayed video signal and the delayed wifi audio are arriving at the same time, so the experience is identical regardless of how you’re listening. But you can’t delay a live event. Shit on stage happens in real time. So WiFi isn’t an acceptable medium for live events.
And Bluetooth is even worse than wifi, because it requires pairing. The Bluetooth protocol requires a handshake between the broadcaster and the receiver, which means it can’t be scaled to larger crowds. Even with the issues of wifi, you can at least broadcast it to an entire room. But for Bluetooth, you would need an individual broadcaster for every single person who wants to connect. It doesn’t scale. It would be like needing to install a new radio antenna for every single person who wants to listen to the radio broadcast. It simply isn’t scalable.
Plus there’s the fact that Bluetooth is a digital system that requires packets just like wifi, which introduces that latency. Even the best Bluetooth systems designed for specific brands (like AirPods being designed specifically for iPhones) have latency. And that’s under ideal conditions. A potential bluetooth system meant for hearing aids wouldn’t be operating under ideal conditions; It would be designed to be compatible with as many different devices as possible, which means you can’t use bespoke programming to reduce latency. And in a venue where you’re hearing both the room noise and the hearing aid, any amount of latency will cause an “echo” effect that makes it completely unusable.
But none of that matters, because I still get annoyed Karens going “but I can connect to my phone, so why can’t I connect to your system?” And even if I bothered explaining all of this, the most I’d get is an entitled scoff.
Yeah that’s terrible. I mentioned elsewhere that my tv uses a different system and it’s actually what they should be hoping you have available. My audiologist said it’s an evolution of the old inductive loops (ah back in the day I almost got one of those designed for personal headphone use). I can’t confirm it is because I’m not taking it apart while trying to remember how the fuck electromagnetic communication works.
Also depending on the performance I’m amazed that people can hook it up. I still turn mine off for concerts, though that may be more the music I like is the sort to make me go deafer than my genes.
Why are medical devices operating on the same band as consumer devices??
Because hearing impaired people want to connect it to their normal devices, like TVs and Phones?
Bluetooth is Bluetooth, no matter the usage. They're only allowed to operate on a specific frequency range.
Bluetooth connectivity is a feature. And tbh I love it, it’s headphones specifically set to compensate for my hearing loss, that I can connect to my phone and theoretically my computer. I can listen to audiobooks without taking out my hearing aids (though switching to dome molds means earbuds fit in without taking them out) and I can make phone calls beam into my ears. Even beyond that, it connects to my phone via Bluetooth and gives me the ability to control settings on them. These settings include different sound settings for situations like meetings as well as muting which I need sometimes because of things like loud coworkers and the stress of always hearing.
Until this inconvenience it managed to take an assistive device from “ugh I have to wear these even though they’re uncomfortable (the discomfort isn’t just the fit, it’s also being able to hear everything) to having enough convenient features that I sometimes wear them at home.
And yeah these nice features do matter because one of the most difficult things about hearing aids is getting people to power through the initial discomfort when they first get them. Also there’s just the nice to have factor. Why shouldn’t medical devices have nice features that can be easily implemented. Like transition lenses or putting a cup holder on a wheelchair.
They have Bluetooth for convenience to help you listen to regular audio sources, but they should definitely have better controls available. Sounds like theirs are permanently in pairing mode
Are these OTC hearing aids? Or prescription ones from a reputable audiologist and brand? Every brand I have worked with require the devices to be in pairing mode to do that (the first 30 to 60 seconds of when the devices turn on)
They’re unitron, and expensive enough they better not be otc, Especially since I got them with a hearing test and everything. And maybe my neighbor accidentally turned their device on as I turned my hearing aids on. I do give them and myself a little break when I get home from work many days
I have a Bluetooth speaker that I use for both my phone and wired via an aux/3.5mm cable to my PC. When hard wired the PC's sound takes preference, which is what I want but it still connects via Bluetooth to my phone every damn time and mutes all the audio coming from my phone!
