Sometimes people forget to turn their hearing aid off. This can be fixed by putting a small reed switch inside the hearing aid, and magnets inside the hearing aid case.
When you put your hearing aid into storage, it will trigger the magnetic reed switch, and turn off the power for the hearing aid.-- mofosyne, Oct 27 2010 Suggest move to science:health:ear or product:audio:personal.

It's got an induction pad in it, that they rest upon. They're some fancy German things... practically invisible and about $12,000.-- infidel, Oct 28 2010 TEN PAST FOUR. AND THERE'S NO NEED TO SHOUT.-- 8th of 7, Oct 28 2010 Sounds doable for cheaper hearing aids.-- nomocrow, Oct 28 2010 + sensible is OK (sometimes)!!-- xandram, Oct 28 2010 random, halfbakery
