Location: The Green Bowl, Pitzer College, Claremont, CA
Description of the space: The Green Bowl is located between East and West Dorms of Phase II at Pitzer College. The circular depression is covered in thick grass with a secant cement wall to one side.
Recording setup: The balloon was popped down in the grassy depression. The recorder was held 2 feet away from the balloon.
Max intensity: 82.81 dB
30 dB drop: 53.01 @ 0.128 seconds
50 dB drop: 32.10 dB @ 0.448 seconds
Minimum intensity: 31.7 dB @ .458 seconds
Back to ambient: ~30 dB @ .5 second
This space absorbed the sound of the popping balloon quickly as a result of the grassy enclosure and the outdoor environment. I hypothesized that the secant cement wall might result in an interesting reverberation however we did not encounter any statistically significant fluctuations in the sound decay.
