Sunset Center, Carmel, California

Current Hall Layout (October 2000)

Case 1. Single source (#3) located at the center of the stage. Listener #1 on the left side of the hall half-way back; Listener #2 near the left rear corner; Listener #3 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 source. Listeners #1, #2, and #3 are shown in blue.

Figure 3. Early Decay Time (EDT) throughout the hall for source “3” at stage center. Typical Decay times between 0.75 and 1.25 seconds are significantly shorter than desired indicating the hall is “dry”. This corresponds with reports from performers and audience.

Figure 4. Reverberation Time (T30) of 1.5 to 2.25 seconds is longer that EDT which is desirable. T30 is longer than EDT due to sound captured in a small reverberation chamber above the performers (above the shell and behind the proscenium).
