To my shock, this syndrome just started happening to me. No fun.

Part of the problem is the semiconductors used in making the devices. They typically run on 1.5 volt cells. That doesn’t leave a lot of overhead for a high signal to noise ratio.

There is an old technology from back in the 80’s and 90’s that was called ‘COMPANDING’ which was a way to increase the signal to noise ratios in solid state electronic devices.

I don’t know if these new modern hearing aids use this circuitry or not but it might prove useful again.............
