On 15th April, 2019 a catastrophic fire broke out in Notre Dame Cathedral. Parisians watched in horror as the spire fell and most of the roof was destroyed. In the aftermath it became clear that a large area was contaminated with toxic dust and lead.

The iconic building, which has dominated the Île de la Cité island in Paris since the Middle Ages, is a national symbol not only for the French but for people all over the world. 

President Macron pledged to build back the cathedral as it was before, and as the planned reopening in December 2024 looms, a huge office structure has mushroomed around it and 500 workers are on site daily as the team race to rebuild it.

The eyes of the world are watching, but Materially Speaking has a story for our ears - the story of its sound.

As a sound specialist himself, Mike Axinn was fascinated when he discovered there is a group exploring the restoration of the acoustics at Notre Dame. He approached Brian F.G. Katz and David Poirier-Quinot at the Sorbonne, and their colleague, sound archeologist Mylène Pardoen, who is co-coordinator with Brian of the scientific acoustics team assisting the reconstruction of Notre Dame, and soon we were off to Paris to hear their stories. We first met Brian and David at a restaurant and then visited their simulator inside the Sorbonne to discover more.

Notre Dame has a special role in western European music’s history and is generally thought of as the cradle of polyphony. Sarah was attracted to this angle as her father, Christopher Monk, was part of the Early Music movement which restored the use of the Renaissance cornett, a woodwind instrument well known in Monteverdi’s music. He also made and played serpents, long snake-shaped instruments that had a central role in music that was performed in Notre Dame many centuries ago. So she approached Volny Hostiou, one of France’s leading serpent players, and we were delighted when he and singer Thomas Van Essen agreed to join us in Paris for some experiments with Brian and David.

We then jumped on a train to Lyon to meet with Mylène Pardoen and learn more about her work as one of the world’s foremost sound archaeologists, tasked with recording the sounds made by stone masons and other artisans in their work, and re-imagining the church’s soundscape at various points in its history.

A key person driving the physical restoration is Pascal Prunet, Chief architect of historic monuments in France and part of the team in charge of restoring Notre-Dame. Prunet explains that their work in restoring the church has revealed many secrets about its construction and the work done by artisans. We were fortunate to hear how his team was able to discover things they never would have learned had it not been for the fire.

As we obviously could not go inside Notre-Dame, Volny and Thomas then kindly arranged for us to hear them play in the Abbey of Rouen, built on a similar scale to nearby Rouen Cathedral, the abbey is famous for both its architecture and its large, unaltered Cavaillé-Coll organ. Here they talked to us about the serpent and their group Les Meslanges, showed us a serpent fresco on the ceiling of the Abbey and played in three different locations.

Finally Mike takes us back to Brian and David’s simulator to compare and contrast the sound of the musicians live in the Abbey of Rouen, and their simulated version of how the music would sound at different historical periods of Notre-Dame’s history.

Thanks also to Frédéric Ménissier who made a great video recording of our visit to the Abbaye of Rouen. You will be able to watch the result on YouTube @materiallyspeakingpodcast nearer the scheduled reopening of Notre Dame, in December 2024.


Thanks and links

We are very grateful to Brian, David, Mylène, Pascal, Volny and Thomas for giving so generously of their time and sharing their expertise and passion. You can learn more about their projects in the following links.

Brian F.G. Katz & David Poirier-Quinot
Brian Katz, originally from the U.S., is an acoustics specialist and leads the Sound Spaces research team. David Poirier-Quinot works with Brian and is a researcher, presently focused on sound spatialisation, perception, and room acoustics simulation for virtual and augmented realities.


Beginning mid April 2024, The Past Has Ears project is launching Whispers of Notre Dame, ‘Ekko of Notre-Dame de Paris’, an immersive audio guide that transports listeners through time and space to the heart of Paris's most treasured landmark. Free on Google Play, Android and iOS. It can be listened to anywhere, but is best with GPS onsite at Notre Dame.
