After listening to this many times, I decided to include them to be tested with some commercial products at Riverbank Acoustical Laboratories.   I recently discovered these in my "attic" files and have reproduced them here.

Egg Cartons do, indeed, have acoustical value.  They measure NRC - 0.40.

However, the graph tells the rest of the story.   While commercial products exhibit a smooth curve, there is a "pothole" in the acoustical road with egg cartons.

Another thing to consider is flammability.  Take an egg carton outside and put a match to it!  Then ask yourself, "Do I still want this on my studio walls?"
