| The same day that recordings were made of the concert, the team also made detailed measurements of the cathedral's specific acoustics. These measurements helped to quantify the acoustic conditions in the cathedral, in 2015. As an example, the [[https://en.wikipedia.org/wiki/Reverberation|reverberation time]], or the time is takes for a sound to decay by 60 dB (to inaudibility) was found to be as follows: | The evening after a small performance in 2015, the team made detailed measurements of the cathedral's specific acoustics.
