Wireless tour guide
Ever been annoyed by the tour guide with the megaphone (or just loud voice) lecturing to the group in a foreign language? | |
No? Actually, neither have I, but it probably happens.
I'd like to see the tour guide using a small FM transmitter, with a range of only a few dozen metres. Each of the tour group has an FM radio; one of the various tiny ones that come in the shape of headphones or earpiece or whatever.
They can
hear the guide clearly, and nobody else is discombobulated by any overloud commentary.
There shouldn't be any problem with using the standard FM band, given the ultra-low power of the transmitter, but a custom solution would make it less likely for patrons to walk off with the radio as they'd be useless for any other purpose.

Not part of the idea, but I like the idea of the tour guide collecting up the headsets, then pressing a button on the transmitter. It sends out a terrifying scream and a shout of "THE ROOF'S FALLING!!" over the radio link (only) and anybody who ducks and looks up is politely reminded to return their earpiece! |

Baked, although probably using different frequencies. You can see it in various places of interest (historic sites, museums etc.), at least here in Europe. |

A variant are prerecorded tours. |
