If I understand correctly, noise cancelling headphones isolate a certain frequency or perhaps a sample of a frequency along an given timeframe. If this is true, then the isolated frequency can be amplified as well as dupilcated. I also assume that these devices have to have some sort of microphones for
audio input. Headphones take the frequencies that they would normally cancel and amplify them so you could hear your friend ask you a question at twice the normal volume so you would end up answering them in a more reduced volume. You could also tune into other conversations when others think you are oblivious. A button would be included to revert their operation to noise cancelling cancelling cancelling headphones with twice the cancelling power.

Prior Art on the HB (with a small difference).
You haven't really described how these devices will work.

There are headphones for gun shooters that work like this; they were linked to from a halfbakery idea. |

I think this is adequately described. Since the microphones and speakers are in place, it's pretty much a software problem. |

Isn't this a hearing aid? |

I would cancel my neighbors barking dog. |

An ignore-a-person setting would be cool. While
hearing everyone else at a normal or amplified
setting, just completely block sound whatsoever
from whomever has a undesired mouth. |
