Apart from its remarkable electrical properties (and also, thermal and acoustical properties), it is the thinnest and lightest substance known, as well as being the strongest (more than 100 times stronger than high-strength steel).
Enthusiasts swear the higher acoustical "resolution" of a mono recording allows individual instruments to be discerned more clearly, despite the paucity of location cues in the sound picture.
More recent acoustical measurements and architectural drawings of the Colón do exist and are consistent with our understanding of what makes good acoustics for opera.
Aerial reconnaissance missions are too costly to be part of their storm surveillance, and estimates made from satellite photographs are unreliable.Nicholas Makris, an acoustical oceanographer at the Massachusetts Institute of Technology, may have an answer.
It is certainly true that even dusty old mono records can deliver greater acoustical punch, while being significantly quieter in silent passages, than a stereo recording.
The original plans had probably no specific acoustical insight (they date from less than ten years after the inauguration of Symphony Hall in Boston, the first auditorium built using principles of modern acoustics).
Henceforth, it would be the record producers, not the performers, who determined the acoustical outcome.
Although the classic espionage agent will never be completely obsolete, some observers have suggested that the role largely has been taken over by machines, including orbiting reconnaissance satellites, long-range cameras, and a variety of sensing, detecting, and acoustical instruments.
It was vacant for six years, and the new owners wisely chose to retain the original signage (a gorgeous neon beacon), handsome Art Deco bar and red-and-cream booths, original terrazzo floors, and acoustical-tile ceiling.
An acoustical-research group of the Hungarian Academy of Sciences has recently reported that the average person talks an hour a day-or if he lives to be 70, nearly 3 years.
In addition there is a large public library, a centre for industrial design, a film museum, and an important musical centre associated with the French conductor and composer Pierre Boulez, known as the Centre for Musical and Acoustical Research (Ircam).
