Reverberation time at Treasury of Atreus
A sound recording has been made (May 1998) of a foot stomp using a Grundig
S-VHS camcorder (LC 550 SC, Hi-Fi audio). The internal microphones were
used and it seems that the AGC (Automatic Gain Control) has not really
effected the measurement of the reverberation times. The below Schroeder
plots give an average of some RT60 of ~ 3.6 sec, which places
it as a building (some 1800 m3) that has an above optimal reverberation
time (Everest [2001], page 151).
Schroeder plots from which reverberation times were computed, are below.
The plots were produced by David Lubman using Cool
Edit Pro v 2.0 for 6-pole octave filters and Spectra
Pro 3.32.16 for Schroeder Integration. I would like to thank David
for his help!
RT60 = ~ 2.5 sec
-
125 Hz-250 Hz
RT60 = ~ 4.5 sec
-
250-500 Hz
RT60 = ~ 3.5 sec
-
500-1000 Hz
RT60 = ~ 3.7 sec
-
1000-2000 Hz
RT60 = ~ 4.0 sec
-
2000-4000 Hz
RT60 = ~ 3.2 sec
