Does Notre Dame Still Sound the Same? | What the Physics?!
Repairing Notre Dame involved more than just stained glass and stone.
When a 2019 fire in Notre Dame cathedral caused devastating destruction, the damage affected more than just the physical: the space’s legendary acoustics were at risk. Discover how a team of dedicated experts raced to save the ancient cathedral’s lost sound.

It is understandable how the audio reverberation of Notre Dame was changed, the central transept vaulted arch was destroyed so sound that nominally would be reflected, went straight up instead. The ambient reverberance now would not be a reflection of how it sounded when the cathedral was finally finished, as it took over. A century for that to occur, which changed the conditions of the first constructed portion of the choir and the apse. The building was given consideration for public vocal consumption as the organ had not yet been invented. The sound initially had monophonic qualities of multiple voices singing the same note, to the polyphonic registers of a full coir.

So there's no comparison points between the pre-fire and after repair acoustics?
Where's the "science" in that?
I know a lot of the human experience of hearing is subjective.
Let us know what the instruments detected.

Spend $1 billion fixing a church instead of $1 billion feeding hungry people seems about right.
Keep up the good work, humans.

Shows us just how weak the current humans are.
Can't create anything worthy

I'm glad they didn't try to make it stay exactly the same. Just make it sound good, we are part of history.

The fire in Notre Dame was seen around the world, and the loss felt widely. Across an ocean, its restoration brings tears to my eyes. So lovely that the sound quality has been restored to its amazing glory!

And….what is the reverb time? What a colossal omission.

Sounds the day it was built mot after inches of sut, spider webs and rotting wood.

Why didn't you include what Katz's latest measurements found?!? You led us up to the brink, and then left us hanging! WHY?
If we have all that science, why say that we might never achieve the sound that Notre Dame once had? That is a glass half-empty. I prefer to think of it as a glass half-full.

I was in Notre Dame in 1968. It was very dark and subdued. I would love to go back to experience the difference. Btw, your earrings are atomic.

I thought we would get to hear some sounds in the video. But still, the science of sound is exciting, just look at how car manufacturers adapt doors and signals etc to sound…pleasurable, or informative!
