Oh, patents! Gehry tubular acoustics

Copyright © Françoise Herrmann

One more utility patent for this phenomenal architect of the turn of the 21st century.
US3672463 titled Acoustic system employing tubular resonators discloses an improved sound dispersion system, towards the audience, for an orchestra, using a tubular structure all around and above the orchestra. The invention effectively eliminates sound dead spots from an orchestra and reinforces low frequencies which are otherwise lost or reduced without means of amplification.
Below appears the patent abstract for US3672463 titled Acoustic system employing tubular resonators and one of the patent drawings as well as an image of a spectacular embodiment of this sound system invention, arising in the Walt Disney Concert Hall in Los Angeles designed by Gehry. The organ appearing like a bouquet of 6134 curved pipes at the center of the concert hall was also designed by Gehry in collaboration with Manuel J. Rosales, a Los Angeles based organ designer.

Improved dispersion of the sound from an orchestra toward an audience and reinforcement of the lower frequencies in said sound are achieved through the use of tubular resonators positioned around and above the orchestra. Resonating chambers are formed in the ends of the tubes by means of transverse partitions. Electrically-driven speakers may be positioned in said tubes. [US3672463]
