I visited the booth of SoundEx products...the fellow there offered a demo of a loud speaker in an Igloo box closed and open showing his material absorbed sound...how that noise relates to an airplane engine I don't know...but anyway I took a sample home.
I placed it in a dish with water and the foam really loaded up pretty quickly, plus it held the water pretty well while I hung it up...seems the cells are pretty available to water and sound absorption...I think I'd be a little concerned using this material in an aircraft...plus looking at it, it looks like something I could cobble together for a whole lot less than he was charging.
The aluminium material bubble cells peeled off of the white celled material when it became wet. Don't know if the piece I receive, while a very small sample, was a good sample of the work or whether the cells glue was not applied on this small sample. But holding a lot of water would concern me more than noise.
