...some $10 million from a pioneer manufacturer of hi-fi equipment, the structure will be closed for five months starting in May 1976. Its entire inner auditorium will be demolished and rebuilt. The cost is put, optimistically perhaps, at $3 million. In charge of the renovations will be Acoustician Cyril M. Harris of Columbia University. He was responsible for the excellent sound in the Metropolitan Opera, and tuned the various halls at Washington's Kennedy Center and, most spectacularly, the new Orchestra Hall in Minneapolis (TIME, Nov. 4). "They've never heard good bass in Fisher Hall," says...
Last week Steinberg led the orchestra through a program of Shostakovich and Mozart that, besides being musically rewarding, demonstrated that the auditorium is an acoustical gem. Heinz Hall has what is called a good throw. Its sound reaches the audience in smooth, vibrant, evenly distributed waves. German Acoustician Heinrich Keilholz removed a lot of old velvet, surrounded the stage with reflector panels (removable for opera and ballet), then hung a larger, fan-shaped reflector out over the main floor. "In the old days," says Steinberg, "Pittsburghers had no way of telling what their orchestra really sounded like. To find...
...Environmental officers are working to correct-rather than penalize-most other routine offenders. Confronted with a case involving a clattering air conditioner, Cosimo Caccavari, the city's top acoustician, asked the owner to draw a floor plan of his house. Then Caccavari suggested moving the air conditioner to another location where it would not face any near neighbor. Similarly, he showed a paint-store owner, whose rooftop ventilators had brought complaints, how to build a noise shield that would stifle the racket. He also proved to officials of an excavating company that the vibrant rat-tat-tat of their...
...would be hard-pressed to find a competent acoustician, heart specialist or surgeon who would find the startle of the sonic boom acceptable to society. Air routes that avoid populated areas and economists who agree with the FAA are equally rare...
...German Acoustician Heinrich Keilholz takes over. Clouds are raised and further patched up. Their function is now described as "decorative." Undulating, floor-to-ceiling panels of plywood constructed around stage. Auditorium walls reshaped. Two-foot-deep "reflector box" constructed around stage apron. Air-conditioning units are muffled. Total cost: $335,000. Critics say echoes persist and bass has developed thudding sound. Consensus is that sound is warmer, but still nothing approaching that of Vienna's Grosser Musikvereinssaal, Amsterdam's Concertgebouw or Boston's Symphony Hall-all built before acoustics became a science...
