Batteries are the New Black

Just a quick post, about something that Lindsay experienced the other night while we were out and about with friends. Another enormous difference between hearing aids and her CI processor: what happens when the batteries die.

I didn’t know this, but hearing aid batteries die slowly, with a very gradual loss of sound. A typical aid battery can last for a week or two. But not so for the power-hungry processor: like a typical smartphone, you have to recharge those batteries every night, and they last for about a day, if she’s lucky. When she isn’t lucky, there is nothing gradual about the sound loss – she can go from hearing to hearing nothing mid-sentence. The processor warns her that the battery level is low, by giving her a few beeps in her ears beforehand, but that’s all she gets. It always surprises her.
