In a specially-engineered "silent room", there are literally
no vibrations of the air that are perceptible as sound, with the
notable exceptions of the sounds made by your respiratory
and circulatory systems. A fascinating experiment would be to
place microscopic microphones in one's inner ears to
determine
what vibrations actually reach it when you are in such a room,
and then place microscopic speaker elements (piezo?) inside
the ears, computer-driven to actively cancel these sounds. What
is it like, for a hearing person, not to hear anything at all? This
experience (in a non-traumatic setting) may actually be very
pleasant - the effects of a sensory-deprivation chamber come
to mind.

They don't work perfectly, but they do help a lot. [rmutt, Jan 16 2001, last modified Oct 17 2004]

These earbuds are very close to what you describe. The 23db of sonic isolation isn't quite complete silence, but it's amazingly close. [egnor, Jan 16 2001, last modified Oct 17 2004]

I would like this set to neutralize all sounds except the music I'm listening to... I like to concentrate fully on the music. |

Public transit application--a person wearing those headphones could enjoy the looks of disgust on every face in sight while smiling back. |

<b&m>ok, fine, but why can't they manufacture such wonderful headphones with more substantial wires than these woefully frail little copper-and-rubber strands? if a set of headphones is *designed* to be used in a non-stationary manner, no doubt somebody is going to inadvertently get caught and yank vigorously on the wire, likely making your new phones useless (get out the soldering iron ;) ) The wiring to the 1/8" jack *always* seems to crap out early and your left to jiggle it in the jack and get spotty sound, at least until you get fed up and go buy a new set of headphones... >( </b&m> |

If you buy better headphones, they'll have a proper strain relief and that won't happen. |

What we really need is a set of headphones that dont
hurt and mishape your ear when you try to listen to your
music, cuz thats REALLY annoying!!! |

I miss the big old cans with the padded rings, for both of the above reasons. They took more power to run, so weren't really much good for walkman type things, but they were comfortable and I never had the wire go bad on them... |

you know, the drug DXM does something very similar to that... |
|

You can certainly still get "big
old cans with the padded rings".
I have a pair myself. You all
need to go read more audiophile
magazines or something. |
