Philharmonic Hall’s acoustics resisted all fixes and remain imperfect decades later.
Evidence
Many small and some moderate-scale improvements were tried on the original Philharmonic Hall. Nothing really worked. Then, Avery Fisher donated funds toward the gutting and rebuilding of Philharmonic Hall in the early 1970s. Avery Fisher Hall was an improvement, but new issues surfaced, and the acoustics remain less than perfect. Modest renovations are planned again. The checkered history of Philharmonic Hall is still being written. — Eric J. Heller, Why You Hear What You Hear- An…, 2582
