 Venice's Church of the Most Holy Redeemer has held a musical celebration every year since its construction in 1592. And recently, the church has inspired debate among historians: How could its echoing chambers2 clearly portray3 the complicated music performed during the festival?

 
A New York University doctoral student named Braxton Boren decided4 to find out. He recorded a choir5 within a non-echoing chamber1
 
Next, he fed that audio into a computer simulation that he built based on the dimensions and materials of the church. The muddled6 reverberations matched actual acoustic7 measurements taken within the empty church, demonstrating that the simulation was accurate. 
 
Finally, Boren recreated what the music sounded like when the church was filled with sound-absorbing tapestries8 and people. The new simulation reduced reverberations from seven seconds long to three and a half, making the music much clearer.
 
And so Boren settled the argument. Although to some historians he was preaching to the choir.
 
Thanks for the minute. For Scientific American's 60-Second Science, I'm Sarah Fecht.
