...principle behind all antinoise devices is the same. Noise is basically a pressure wave traveling through the air. Antinoise is the mirror image of that wave, an equal and opposite vibration exactly 180 degrees out of phase with the noise to be blocked. When noise and antinoise collide, they interact with what is called destructive interference, canceling each other out. The idea is not new; generations of high-school physics students have seen destructive interference demonstrated with undulating Slinkies or jump ropes. But it is only recently -- with the advent of small, high-speed signal processors -- that scientists have...
...when incoming sound waves rise and pulls it back when the sound waves fall. Alternatively, antinoise waves can be created digitally, using a signal processor to convert incoming sound waves into a stream of numbers. Given those numbers, computers can quickly calculate the frequency and amplitude of the mirror-image waves. Those specifications are then fed to a conventional speaker and broadcast into the air. Sounds that the system wants to preserve, like human voices, can be subtracted out in the beginning of the process and added back...
...hold as 'twere the mirror up to nature," is written in heavily ornamented lettering above the stage in the Boston University Theatre. The Huntington Theatre Company seems to have taken this phrase to heart...
...pages mirror my unsettled feeling. On one hand, we can read warnings from academics, hard-line Cold Warriors and eternal pessimists about how the demise of polarity could take us back to a Bismarckian Europe. But much more common, at least until the dust settles, are the jubilations over the domino theory in reverse. Every-where we're reminded what an exciting time it is to be alive...
...should one suppose that these are dreaming connoisseurs who have just relinquished the ink block and the brush to dabble in the art of the namban, or round-eyed barbarian. Shigeki Kameyama, representing the Mountain Tortoise Gallery in Tokyo, last week bought, among other things, Picasso's The Mirror at $26.4 million. The week before, he had also purchased De Kooning's Interchange at $20.68 million and a Brice Marden drawing at $500,000 at Sotheby's. Kameyama is known to other dealers as "Oddjob," after Goldfinger's hat-flinging chauffeur...
