Sunset Center, Carmel, California

Current Hall Layout (Wood Ceiling replaced with Plaster)

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 of 2 to 3 seconds are somewhat longer than desired.

Figure 4. Reverberation Time (T30) of over 3 seconds is longer that EDT which is desireable. But both T30 and EDT are longer than desired.
