10 USES Home to New York Philharmonic, as well as host to a number of visiting orchestras. Leonard Bernstein s Young People s Concerts among the first televised performance from the hall. NOT JUST A SYMPHONY HALL Miles Davis 1964; Simon & Garfunkel 1967; Queen Hall is frequent location for graduation ceremonies and other events. Plans for major renovation of the auditorium in 2019 to make it a more adaptable performance space.

11 AN AURAL HISTORY The New York Philharmonic BUILT Architect Max Abromovitz designed a new International style home for New York s symphony orchestra. Leo Beranek was acoustical consultant. He recommended a shoebox design with narrowlyspaced parallel sides to seat 2,400. The plans called for placing the farthest seats an intimate 138 feet from the stage, with low balconies putting the highest seat only 45 feet above the stage Critics clamored for the seating equivalent of Carnegie Hall (then scheduled for demolition ), and capacity was increased to 2,738 seats late in the design stage, necessitating changes to the building s volume and shape that invalidated much of the acoustical planning. The hall got scathing reviews: The orchestra sounded dry and lifeless. Rather than being immersed in the sound, audience members felt it emanate from the stage. There was no sense of being in a room filled with music. There were dead spots, and too little bass compared to treble. Some seat locations heard echoes, others barely heard anything. If it was bad for the audience, it was worse for the musicians who could not hear what they or others were playing. Bruce Bliven, A Better Sound in The New Yorker 2M of adjustments made to try and improve hall acoustics None of the attempts to tune the hall worked Avery Fisher Hall Renamed after a prominent benefactor involved in making hi-fi sound equipment who donated $10M to support a major redesign RENAMED The seating capacity is too large and the sidewalls are too far apart to provide early reflections to the center seats. The ceiling is high, increasing reverberation time, but the clouds are too high to adequately reinforce early reflections. The bass is weak because the very large stage does not adequately reinforce the low string instruments. R.C. Ehle, Music Teacher International Magazine article

12 Major Redesign GUTTED Cyril Harris, an acoustics expert, worked with project architect Philip Johnson and a major renovation that included demolishing the inside of the hall and rebuilding a new hall within the outside framework and façade. This redesign achieved a warmer, more encompassing sound But the brasses remained bright, and the bass was weak. Musicians also reported problems hearing each other. Addressing the Stage Acoustics Solid maple concave surfaces were installed on the stage s side walls and ceiling to help focus sound from different parts of the stage evenly toward the audience and the performers themselves. 3 fiberglass pillows were added to the sides to deaden vibrations. Retractable glass shelves were placed above the pillows to allow tuning. A stepped oval glass reflector was added above the stage to direct sound toward the audience, and a small platform was placed at the rear of the stage to provide adjustable sound control for performers. RESURFACED The reconstruction of Philharmonic Hall is said to have changed the acoustics of the space tremendously. The resulting sound was hailed as by critics as sumptuous, warm, full, voluptuous, and lively. These were ways of describing an effect that Harris had been aiming for all along: the ability to feel the music in the floor and around oneself, the feeling of being engulfed in sound. New York Philharmonic pursued returning to Carnegie Hall. Talks abandoned. Hall Renamed. $500 Million Overhaul Initiated. REVAMP PLANNED Josh Hudelson, A Musical Miscarriage The hall was rechristened The David Geffen Hall in September, 2015, when the donor gave $100 million toward a planned $500 million interior overhaul to commence in The goal is to modify the space to serve as a multi-purpose performance hall, with a reconfigurable performance area (thrust stage, proscenium, theater in the round), enhanced acoustics, better aesthetics, a socially-inviting foyer, more rehearsal space, and possibly more seating.

13 NEW YORK PHILHARMONIC IN MUSIC, TERRACED DYNAMICS ARE A Sudden or Dramatic Shift AS DESIGNED AS BUILT Abramovitz changed the design of the balconies, having them dramatically sweep down toward the stage rather than gradually step-down as Beranek had recommended and the building committee had approved. To address the steeper slope of the balconies, Beranek added more individually adjustable reflective ceiling clouds, extending over most of the audience (a change that had disastrous acoustical effects). By bulging the side walls of the hall out into a barrel shape, the architect managed to fit 258 more seats onto the main floor. But these concave walls created major acoustical problems. To compensate for the concave walls, Beranek specified wooden diffusers on the walls to minimize the focusing effect. For budgetary reasons, these were omitted.

14 DISCORDANT NOTES Michael Barron. Auditorium Acoustics in Architectural Design. Taylor & Francis, 1993, p. 95. Barron s analysis of the 1962 acoustical problems LOOK OUT FOR THE CLOUDS Examination of the plan and section reveals several anomalies. The main floor rake was shallow, the balcony overhangs excessive, and the rear wall is concave in both plan and section, which encouraged echoes back to the stage. The curvature on the side walls meant that there some focusing at the rear of the stalls, and that many stall seats received no lateral reflections. Finally, a peculiarity of the stage design is its remarkable size, enough for about 170 musicians, which probably left orchestras too widely dispersed. But many of these features were found elsewhere, and... even in combination they do not seem sufficient to produce such disappointing acoustics. The major fault, which was soon isolated, related to the behavior of the suspended reflectors ("clouds"). Owing to the small size and regularity of the double layer of reflector panels, the array did not reflect bass sound. In addition, the low percentage of open area (less than 50% in the Philharmonic Hall vs. the recommended minimum open of 70%) created a poorly coupled acoustic space above the array, inhibiting reverberation. The problematic clouds were removed in 1969 and replaced with a stepped ceiling. In 1992, solid maple concave surfaces were installed on the side walls and suspended from the stage ceiling.

15 BEST PRACTICES Adapted from Momin Zaki, Auditorium Acoustics. REQUIREMENTS VARIABLES Low ambient noise Reasonable acoustic gain Reverberation time of 2 seconds Avoid artifacts such as echo Shape Size (dimensions, volume, capacity) Surface layout Materials (textured vs. flat; absorbent vs. reflective) DEFECTS Echo Delayed reflection Sound shadow Sound concentration SHAPE BALCONY Shoebox is best for music to avoid flutter echoes. Splayed side walls reflect sound to the rear of the hall. Splays should be avoided in concert halls, but if must splay, Ideally, depth = height (2x height is max. to avoid acoustical shadows). Add reflecting surfaces to underside of balcony. Place absorptive panels on the front of balcony parapets.

16 BEST PRACTICES (continued) Adapted from Momin Zaki, Auditorium Acoustics. DIMENSIONS The maximum recommended distance from back seat to stage is 130 feet. Volume CEILING Ceiling reflectors ( clouds ) direct sound to the audience. Length and width of cloud panels should be at least 5x wavelength of lowest frequency to be reflected. Ideal height = ⅓ to ½ of room width. Avoid concave ceiling surfaces to prevent sound foci. Impacts reverberation and loudness. Aim for 275 cubic feet per seat ( range). WALLS Concave shapes focus sound. Avoid concave rear walls. Side walls should avoid parallelism. Tilt or splay wall surfaces to direct and diffuse reflected. Stage and front of hall should be reflective; rear should be absorptive. ABSORPTION Audiences provide most of the absorption, so room surfaces can be relatively reflective. REFLECTION Audiences provide most of the absorption, so room surfaces can be relatively reflective. Reflective front stage area provides strong early reflections that enhance sound. Conversely, late reflections and reverberations from rear walls produce echoes. FLOORS A sloping (raked) floor allows less absorption, and improves sight lines. Generally, slope of performance hall should be at least 8, but not more than 35.

17 CONCLUSIONS The acoustical failings of the initial1962 New York Philharmonic hall can be attributed to: The curvature of the side walls which focused sound to the rear and inhibited lateral reflections. The wooden diffusers which were specified to address this issue were omitted for budgetary reasons. The small regular clouds in the ceiling did not reflect bass. Additionally, the lack of open space above the cloud array inhibited reverberation. Adding more seats reduced the volume to 230 cu. ft. per audience member, which is at the low end for concert hall and may have impacted loudness and reverberation time adversely. Sharply angled overhanging balconies trapped sound and created dead spots. The stage s sound issues after the1976 redesign were caused by: Lack of variety in shape and material of stage ceiling diffusers. Need for additional diffusers on the side of the stage.

18 SUMMARY The New York Philharmonic was the among the first concert halls designed with modern acoustical principles. The operative word being designed. The architect and sound engineer fell victim to public pressure to expand the seating within the initial footprint and budget constraints. The late changes in the form and layout destroyed the hall s acoustics. As an object lesson in what not to do, the sad tale of the 9 different attempts to right the initial wrong is illuminating. Architecturally, the hall is a paragon of mid-century modern design, and from that perspective, it was successful from the outset. The modern design era was premised on openness, adaptability, and democratization. The transparency of the design of the Avery Fisher hall helped join the music experience on the interior with the outside life of the city. Younger crowds gathered in the plaza it became a scene. But the way orchestral music should be experienced is deeply rooted in a tradition that historically dictated a fixed set of design requirements. Says Edward Rothstein of the New York Times, Other musics visit the concert hall; they are not at home in it.. Although it may be a chimera, for the next phase of its existence, the New York Philharmonic Hall, a.k.a Avery Fisher Hall, a.k.a David Geffen Hall will attempt to become a chameleon expanding its remit to serve as a multi-use performing arts center, perhaps with a larger capacity, certainly with a more flexible stage configuration, and definitely with a better acoustical experience than it has delivered for much of its storied 50-year history. Whether it is possible to serve all of those purposes in an envelope that has never fully succeeded as a symphony hall is a challenging puzzle for the next set of architects.
