Interesting topic, and ran into this in search of noise levels:
https://www.faa.gov/regulations_poli...cumentID/22945
Worth noting that these are estimated noise levels instead of measured noise levels, but the document is for take off noise with presented flap settings.
You'll find the list on document
AC 36-3H Including Change1
On top of the list is Concorde with 112dBA, and eg aforementioned DC-3 has 85dBA.
Cessna 185 goes with 66dBA (no mention of the prop). 150/152 is at 59dBA, and on the bottom of the list is AA-5B TIGER wtih 52dBA.
And out of sheer interest a few picks: twin comanche 70,6dBA. Navajo up to 74dBA.
The Paris is rated at 80,9dBA.
