With my previous hearing aid I noticed that visiting a wide variety of web sites would cause a change in the amplification of environmental noise. I always assumed it was doing something with Bluetooth, and probably not for a good reason. This is with an iPhone 13 and one Kirkland/phonak hearing aid.

I haven’t noticed this recently, but I also now have two newer Phonak hearing aids and a few iOS updates have happened. Maybe the silent Bluetooth shenanigans are less disruptive to my new aids or the programming is different. Surely shenanigans continue.

I wear Phonak CI processors. It's not just you. I've also experienced the volume drop on a few sites and apps. The Amazon iOS app does this. Each time I leave the app, ambient audio returns to normal.

		They’re kindly turning down the background noise so you can focus on shopping and buying more stuff.

It seems far more likely that your cheap hearing aids are sensitive to certain RF frequencies and the background javascript is causing different patterns of load on the phone's CPU.

I would suspect that this only happens when you're charging and it is likely the charger or cable not being properly shielded.

		The cheap hearing aid cost $750 for one and is substantially the same as the same thing sold from standalone audiologists for much more. These are not cheap over the counter devices. Charging only happens while in the cradle, not while worn.
