No, I've been following this group for a long time, and haven't seen this
BUT - I am so *GLAD* to hear someone else report this!! I am an aided
audiologist, and last November, I was shopping with my cousin at a local
outlet mall. We walked into a music store and I actually ducked from the
sound that came into my hearing aid as we walked through the theft sensors!
My first suspicion, was that my hearing aid had accidentally been switched to
the "T" switch, and I was picking up the electromagnetic field from the
sensors that way.
But I checked my HA, and it was indeed in the correct position, so I (being
the researcher and curious person I am) walked out the door and back in again.
I was "test-driving" a programmable hearing aid at the time, and had a meeting
with the hearing aid representative the next week. I asked him about it and
the answer was somewhere between "impossible" and "highly unlikely", and "must
be something wrong with the hearing aid".
So, tell your son, he's not alone, and now you've got me curious about this
