ACOUSTICAL SYSTEM EMPLOYING TUBULAR RESONATORS |
摘要 |
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.
