One of the cooler things I've been getting up to is measurements of materials that were present or would have been present inside the cathedral throughout its history. This photo is from a trip I took recently to the LNE - Trappes, who were kind enough to loan us their reverberation chamber for Sabine measurements of some unusual materials.

Old format, but an accurate depiction of my morning's attempt at deciphering the comments in my python script.
