When the iconic Notre Dame cathedral in Paris caught fire last month, people found some hope in the news that scientist Andrew Tallon had used laser scanning to create precisely detailed maps of the interior and exterior of the cathedral—an invaluable aid as Paris rebuilds this landmark structure.
The acoustics of the cathedral—how it sounds—are also part of its cultural heritage, and given the ephemeral nature of sound, acoustical characteristics can be far trickier to preserve or reproduce. Fortunately, a group of French acousticians made detailed measurements of Notre Dame’s “soundscape” over the last few years, along with two other cathedrals. That data will now be instrumental in helping architects factor acoustics into their reconstruction plans.
