Ever since the beginning of time, people have hated crying
babies.
This has been magnified a billion times when stuck in an
airplane.
Noise cancellation headphones work extremely well on
airplanes to reduce fatigue, by emitting sound waves *exactly
opposite* the waves emitted by jet,
etc on an airplane.
Circuitry and technology has advanced to the point where it
can easily (at least over the period of 3 minutes) analyze the
sound pattern coming from a screaming little crumb-cruncher
(Waaaah... Hic....Waaah....blaaaHHH HAAA HAAA.. Hic..
Waaaaa...) and negate the soundwaves accordingly.
Sure, It'll use more batteries, but it's worth it.
Side of the headphones can have a little compartment for
storing xanax and apple-juice powder, just in case batteries
run out.

Headphones which relay the sounds of a microphone placed inside the engine would easily drown out the noise of even the most vocal unhappy tyke. |
|
| |
Also, 3 minutes of analysis would give you the inverted soundwave about 2.999 minutes too late. |

Perhaps not 100%.. but I disagree.
Hearing aid technology is tremendously better now than
in the past 10 years. Remove the need for compactness,
put circuitry in between the mic and amplification, and
simply "negate" the signal.. that's it.. |
|
| |
Only thing is.. it would provide PERFECT SILENCE and
drown out the two foreigners from different countries
fighting for luggage rack space in front of you as well. |
|
| |
So you lose some entertainment, but it's a trade-off.. |

//put circuitry in between the mic and amplification, and simply "negate" the signal//
Or simply use a 50 cent pair of earplugs. |

Ow, [Krelnik].
Your occams razor is stabbing me in the back... |

'wax, there's something to be said for that. But given the choice, I think I'll stick with my 'always on' hearing. |
