Space Description: The atrium outside of the Lyon Court laundry room has low ceilings. The entire area in made of hard concrete, so every sound in “boomy”. The atrium has walkways that lead to the courtyard in between Harwood Court and Lyon Court, and to the open space between Harwood and Mudd-Blaisdell, a neighboring dorm. The recording took place at 9:15 PM on February 28, 2017.

Recording Setup: The TASCAM DR-40 Linear PCM was placed on a bench attached to the wall, and was facing towards the walkways leading away. The balloon (approx 18″) was tossed into the air, then popped when it was about 4′ off the ground, and about 3′ away from the recording device.

Reverberation Times:

Max Intensity: 87.5 dB

-30 dB: .796 Seconds

-50dB: 1.737 Seconds

Minimum Intensity: 32.3 dB after 2.6 Seconds

Acoustic Description: Although the atrium itself is fairly closed off, the area around it is very open, so once the sound escapes, there is nothing for it to echo off of. The graph shows that there were not many bumps in the decay. This is because of the lack of echo that the space produces – the sound is amplified due to the enclosure, but the sound is able to escape to where it does not echo.
