Cone of Silence

Distortion field that limits the carrying power of voice or other vibration; it accomplishes noise reduction with an image-vibration 180 degrees out of phase. (Read the full article)

"In my freshman dorm room at the University of Dayton, there was a spot where the sound of the fire alarm (which was constantly going off for no reason) was greatly diminished. Not exactly a cone of silence, though."

"The "cone of silence" has been produced. Noise Cancellation Technologies and other newer companies have taken their active-cancellation systems and put them on windows or plates to create-literally-a silent area nearby. Usually used to kill AMBIENT noise to allow conversation, I'm not sure it does much to prevent eavesdropping. How effective? Around a running diesel generator, where talking is nearly impossible, in the silenced-area, it's pretty tolerable. Bad side effect of all active cancellation technology, though: It is iffectively DOUBLING the acoustic energy in the environment, so standing wherever the benefit is lost is now TWICE as noisy. (One reason it was never seriously considered for a Museum exhibit I was working on some years ago.) Maxwell Smart (and Mel Brooks) probably deserve royalties..."

"In Arthur C. Clark's short story collection, "Tales from the White Heart". There is a tale told of a device called the Fenton Silencer which silenced an entire Opra. The other stories in the collection are very good and quite funny. Highly recomended."

"Forgot to mention the date. 1957 is when the book "Tales from the White Heart" was first published. "

"there used to be an aircraft electronic landing approach device refered to as the cone of silence, on approach the pilot heard ...... if he was to far left and ----- if to far to the right if on correct approach he heard nothing through his headphones, hence in the 'cone of silence'"

"I don't think it was so much that the Get Smart version didn't work, as that they were being used wrong - each bubble created a silent area around the user, but since each user had their own bubble, they could not hear each other. (I remember a conference room scene, possibly from one of the movies, that had multiple bubbles around a table, which had the same working-but-useless effect.)"
