The new acoustics of New York’s famed Carnegie Hall--for decades considered the country’s best concert facility before its 1986 renovation--are being fine-tuned, according to violinist Isaac Stern, president of the hall’s parent corporation. Stern said the stage will now be surrounded by mobile wooden acoustical panels which will help absorb some of the new Carnegie’s over-abundant midrange reproduction. Stern also said the acoustics of the hall have been examined and re-examined frequently since the hall reopened in 1987.
