Acoustic Space: Edmunds Breezeway


Loading map...



Space Description: This balloon pop took place in the breezeway of Edmunds, between the entrances of the two different buildings of Edmunds. The left, right, top, and bottom of where I was standing was made of the same smooth concrete material, and the recording took place in the middle of the breezeway. The recording was taken around 5:00 P.M.

Recording Setup: The recorder used was the TASCAM DR-40, and it was placed about 4 feet from the ground and about 5 feet away from the balloon.

Reverberation Time:

Max Intensity: 86.14 dB

30 dB drop: 0.896 seconds

50 dB drop: 2.325 seconds

60 dB drop: the recording never drops 60 dB.

Minimum intensity: 28.342 dB after 4.32 seconds

Back to ambient levels: 32.803 dB after 2.43 seconds

Acoustic Description: The breezeway was not a very open space and resembled a tunnel, so there was quite a bit of reverberation because sound would bounce back after it hit one of the many walls that it would encounter. It is visible form the spectrogram that the echo of the pop was sustained for longer than usual, but eventually returned back to its ambient levels after a couple of seconds. The sound was able to finally escape through the entrances and the exits of the breezeway, but only after bouncing on the ceiling, ground, and walls, which were characteristic of this acoustic space.
