Sunset Center, Carmel, California

Renovated Hall Layout A

Case A. Single source (#3) located at the center of the stage; Listener #1 on the right side of the hall half-way back; Listener #2 near the left rear corner. Listener #3 is at the center of the hall.

Figure 1. Parametric view of hall and stage; red “3” is the sound source. Listeners #1, “2”, and #3 are shown in blue.

Figure 2. Plan view of hall and stage; red “3” is the sound. Listeners #1, “2”, and #3 are shown in blue.

Figure 3. Early Decay Time (EDT)throughout the hall for source “3” at the center of the stage. Typical Decay times of 1.5 to 2.25 seconds are considered very good.

Figure 4. . Reverberation Time (T30) of 2.0 to 2.75 seconds is longer that EDT which is desireable. The times for both T30 and EDT are considered very good.

Listener #1 (Left Side of Hall)

Figure 5a. Reflectogram Figure 5b. Sound Rose

This result is worse than a similar seat in the hall in its Oct 2000 configuration. This seat is too close to a 90% transparent arch spanning the width of the hall.

Listener #2 (Left Side, Rear of the Hall)

This results is similar to the same case run for the hall in its October 2000 configuration.
Listener #3 (Center of Hall)
