Hearing aids can be very useful because they allow the user to stare blankly at a person and say "sorry what did you say" repeatedly.
However sometimes the user wants to actually have a conversation with a person.
This set of discreet lapel mics connects to the hearing aid. The user can hand out
lapel mics to the people they wish to have a conversation with. Each of these persons clips a lapel mic onto their lapel and then they can talk normally to the hearing aid user. Other people can be pointedly not offered a mic so that they can be rudely excluded from the conversation.
If the mic is carried out of range of the hearing aid it starts to beep, thus annoying the wearer enough to make them give the thing back to the hearing aid user.

[a1], those Roger units look pretty neat. Next step would be a directional system, so you can have multiple people wearing a mic, but only the one you're looking at is louder in your hearing aids. |
