Scenario: a group of people are gathered around a table in a noisy pub or bar. Unfortuantely the ambient sound level is so high as to make conversation extremely difficult.
Hence the Bluetooth private chat box. It's a simple bluetooth audio switch. On the basis that all the people round the table
have a bluetooth earpiece and a bluetooth enabled phone, they all bond their phones with the chat box.
A PAN is then created which links the earpieces on a voice-keyed basis; the box also contains a microphone which performs noise cancellation on the signal, improving audibility.
Nobody neeeds to shout, everyone can hear, and even someone who's gone to the bar for more drinks is still part of the conversation.

Very useful inside a helicopter, even if it's still on the ground, waiting for a middle-aged, aviorotophobic to pluck up the courage to board. |

I could use this. After three or four drinks I lose the ability to tune out background noise, making conversation in a noisy pub almost impossible. That and the fact that I talk quietly anyway. |

I've wondered why this doesn't exist already. Here's another idea for you:
Hearing aids with the same capability. |

I think this might make a very challenging project for a final year undergrad or Masters student. |

It's not a completely simple concept - you'd have to work out a contention mechanism (maybe push-to-talk). However, having a central controller makes it easier than an ad-hoc approach (which would require a fully connected mesh or multi-hop topology). |

Wow, which Bluetooth (initials removed to lesson indeciphrable offence) headset do you use? I've tried a bunch and none of them can hear as well as I can. There are some bone conduction sets and a new one that uses something similar that might work and if they did, this is a great idea. Bun(+) I guess bars would be good too, but this would sell big at lots noisy places that presently use radios like motorcycling, skiing, cycling, warehouses and other noisy workplaces. |

Motorola H350; and be so good as to remove the spawn-of-satan glyph [letter after A, letter before U] from your annotation, lest we be compelled by good taste to delete the entire thing, and cleanse the land with fire and the sword and sowing the ground with salt. |

"Bluetooth" is fine; sadly the actual rune is not yet widely available in character sets. But what you have put is positively offensive .... |

Argh, I went right through that anno looking for an A and a U with something weird between. |

You're looking for a smack, aren't you ? |

You're not tall enough, pal. |

If the background noise which makes these necessary is some sort of objectionble music, and everyone's wearing blueteeth headsets (note the plural form), then get rid of the music, and just play it at a reduced volume through the headsets, when someone in your network isn't talking. |
